    <summary class="faq-q">Why does SunScope sometimes show a lower temperature than my regular weather app?</summary>
    <p class="faq-a">Wind chill and precipitation both reduce felt temperature. If it's raining or blustery, the SunSoak value will be noticeably lower than the thermometer reading — which is exactly what your body experiences.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">What is UTCI and why is it better than a standard feels-like temperature?</summary>
    <p class="faq-a">The Universal Thermal Climate Index (UTCI) is a peer-reviewed biometeorological standard developed by Bröde et al. (2012) and used in public health systems worldwide. Unlike simple "feels like" values — which typically only apply a basic wind-chill or heat-index formula — UTCI combines air temperature, humidity, wind speed, and the full solar radiation load using a physiological model of the human body. It accounts for the mean radiant temperature your skin "sees" from all surrounding surfaces, not just the air around you. This makes it a much more accurate predictor of actual thermal comfort and heat stress.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">How hot does a car get in the sun?</summary>
    <p class="faq-a">A sealed car in direct sunlight can reach cabin temperatures 20–30 °C above outside air temperature within 30–45 minutes. On a 25 °C day with strong sun, cabin air can hit 50–55 °C. SunScope models this hour by hour using the actual solar radiation forecast for your location, accounting for body panel conduction and window solar gain. Select the Vehicle profile and choose your vehicle type to see the estimate. Motorhomes and caravans use a separate insulated occupied-space model, so they warm much less aggressively than cars in heat, but can also stay several degrees warmer than outside air on cool sunny days. Values above 35 °C are dangerous for children and pets; above 45 °C can be fatal within minutes.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">Does opening car windows reduce the temperature inside?</summary>
    <p class="faq-a">Yes, significantly. Open windows allow convective airflow to flush hot cabin air out continuously, reducing the heat build-up by roughly 60–80% compared to a sealed vehicle. SunScope's Vehicle column has a Ventilation toggle that switches the physics model to a ventilated state, showing you the estimated cabin temperature with windows open compared to fully sealed.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">Is it safe to leave a dog in a parked car?</summary>
    <p class="faq-a">No — on any warm or sunny day, even with cloud cover, a sealed vehicle heats up rapidly to temperatures that can cause heatstroke and death in animals within minutes. Dogs cannot cool themselves as efficiently as humans and are at risk at cabin temperatures above 32 °C. SunScope's Vehicle interior column gives an hour-by-hour estimate of cabin temperature: if the forecast shows values in amber (above 35 °C) or red (above 45 °C), the vehicle is not safe for a dog, cat, or young child, even for a few minutes.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">How do I keep my house cool in a heatwave without air conditioning?</summary>
    <p class="faq-a">The standard approach is to keep curtains and blinds closed during the day to block direct solar gain through windows, then open windows once the outdoor air temperature drops below the indoor temperature — usually in the evening or early morning. SunScope's Home profile lets you select your building type (brick, modern, Victorian terrace, stone cottage, timber frame, flat, or conservatory) so the model reflects how your building actually heats up. Ticking Managed shows what you could achieve by following this advice, hour by hour — so you can see exactly when to open up for maximum benefit and how much difference it actually makes.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">Why is my house hotter in the evening than during the day?</summary>
    <p class="faq-a">Building materials absorb heat slowly throughout the day and release it gradually over several hours — a property called thermal mass. How pronounced the effect is depends heavily on construction: a solid stone cottage or Victorian terrace has very high thermal mass and can stay warm well into the night, while a timber frame new build or conservatory responds almost immediately to outdoor temperature changes. SunScope's building type dropdown lets you match the model to your actual home, so the indoor temperature lag it shows reflects your building rather than an average.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">How hot does pavement or concrete get in summer?</summary>
    <p class="faq-a">Exposed concrete and tarmac can be 15–25 °C hotter than the surrounding air on a sunny day. Unlike grass, they have no evaporative cooling mechanism and their dark colour means they absorb a large fraction of incoming solar radiation. This is a real hazard for dogs walking on pavements, barefoot children, and cyclists — and it also radiates heat back upward, making urban areas feel significantly warmer than open countryside. SunScope's Concrete surface column estimates this temperature using an energy-balance model driven by the real solar radiation forecast.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">What is UV-A and UV-B and what is the difference?</summary>
    <p class="faq-a">UV-A has a longer wavelength and penetrates deeper into the skin. It is present throughout all daylight hours, passes through glass, and is the primary cause of long-term skin ageing and contributes to some skin cancers. UV-B has a shorter wavelength, causes sunburn directly, and drives vitamin D production. UV-B intensity is much more angle-dependent: it is strongest when the sun is high and falls sharply in the early morning and late afternoon due to the longer atmospheric path the radiation has to travel. SunScope shows both indices separately so you can make informed decisions about both immediate burn risk and long-term UV exposure.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">How long can I spend in the sun before I get sunburned?</summary>
    <p class="faq-a">It depends on your skin type and the current UV index. SunScope's Burn time column estimates the minutes to one Minimal Erythemal Dose (MED) — the clinical threshold for the onset of sunburn — based on the UV forecast and your Fitzpatrick skin type, selectable from the column bar. Fair skin (type I–II) may burn in under 10 minutes at UV index 8+; darker skin (type V–VI) can tolerate significantly longer exposure. These figures assume no sunscreen and direct, unshaded exposure.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">When is it safe to spray crops or apply pesticides?</summary>
    <p class="faq-a">Safe spraying requires low wind speeds (typically below 3 m/s), low temperatures to minimise evaporation and drift, and ideally no rain forecast within several hours. SunScope's Farming profile shows wind speed and direction, air temperature, relative humidity, dew point (to assess inversion risk and overnight settling conditions), and precipitation — giving you all the variables you need in one view without switching between apps.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">What soil temperature do seeds need to germinate?</summary>
    <p class="faq-a">Most vegetable seeds need soil temperatures above 7–10 °C to germinate reliably, with warm-season crops like courgettes, beans, and sweetcorn requiring 12–15 °C or more. SunScope shows both surface soil temperature and 6 cm depth temperature — the root zone where germination actually happens. The 6 cm figure lags behind the surface by several hours and gives a more realistic picture of what seeds in the ground are actually experiencing.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">How can I tell if the ground is too wet for a motorhome or caravan?</summary>
    <p class="faq-a">SunScope's soil moisture column shows the water saturation of the top centimetre of soil as a percentage. A reading above 40% indicates saturated ground where a heavy vehicle is likely to sink or churn the surface. Below 20% is dry and firm. The Vehicle profile includes soil moisture by default precisely for motorhome and caravan users who need to assess pitch suitability before arriving on site.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">Does SunScope show air quality or pollen forecasts?</summary>
    <p class="faq-a">Yes. Three air environment columns sit together after Cloud cover in the table: <strong>Visibility</strong> (horizontal visibility in km — useful for fog, haze, and driving conditions), <strong>AQI</strong> (the European Air Quality Index combining PM2.5, PM10, ozone, NO₂, and SO₂ in a 0–100+ scale), and <strong>Pollen</strong> (concentration in grains per cubic metre with a type picker — grass, birch, alder, mugwort, olive, ragweed, or total). All three are sourced from the Copernicus CAMS forecast. Toggle them on or off using the column buttons above the table.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">What does the weather icon and temperature on each day tab mean?</summary>
    <p class="faq-a">Each day tab in the date strip shows a small weather icon representing the dominant daytime sky conditions — a sun disc for clear days, cloud variants (wispy cirrus, scattered cumulus, overcast) for cloudy days, or a precipitation icon for rainy or snowy days. Below the icon are the day's high and low SunSoak felt temperatures in warm and cool colours. The icon is derived from actual daytime solar elevation and cloud data, so it reflects the real character of the day rather than a generic symbol.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">What are the weather event banners above the forecast table?</summary>
    <p class="faq-a">When notable weather conditions are forecast — such as a ground frost, strong wind warning, fog, or a heat event — a banner with a brief alert appears above the table. Tapping or clicking the event icon opens a description popup with more detail about what the condition means and what to watch out for. Multiple events can appear at once if conditions warrant.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">How far ahead does the forecast go?</summary>
    <p class="faq-a">The free tier shows 3 days of hourly data. SunScope Extra unlocks all 14 days. The forecast auto-refreshes every 5 minutes while the page is open, so the current hour always reflects the latest available data from Open-Meteo.</p>
  </details>
  <details class="faq-block">
    <summary class="faq-q">How accurate is SunScope?</summary>
    <p class="faq-a">SunScope uses Open-Meteo forecast data sourced from ECMWF and national meteorological services — the same underlying models used by professional forecasters. The UTCI calculation follows the peer-reviewed Bröde 2012 polynomial exactly. The derived columns (vehicle temperature, indoor temperature, concrete surface, UV) are physics-based estimates rather than measured values, and should be treated as informed approximations. Real-world values will vary based on local factors like building construction, shading, surface colour, and vegetation.</p>

    <summary class="faq-q">Is SunScope free?</summary>
    <p class="faq-a">The core forecast — Basic, Home, Vehicle, Farming, and the Places (Urban, Beach, Events) variants — is free for any location worldwide. SunScope Extra (£2/month) unlocks 14-day forecasts, the specialist Places variants (Festival, Winter Sports, Naturist, Sailing), the Temps comparison profile, and Custom column control.</p>

    <summary class="faq-q">Does SunScope work outside the UK?</summary>
    <p class="faq-a">Yes — SunScope works for any location worldwide. Search for any city, town, or village using the search bar. The indoor temperature model offers seven building types — brick, modern insulated, Victorian terrace, stone cottage, timber frame, top-floor flat, and conservatory — so you can pick the one that best matches your building wherever you are. All other columns (UTCI, vehicle, UV, soil, concrete) are fully location-agnostic.</p>

    <summary class="faq-q">What is the difference between UTCI and heat index?</summary>
    <p class="faq-a">Heat index is a simple table-based formula that adjusts air temperature for humidity only — it was designed for shade conditions and ignores wind and solar radiation entirely. UTCI is a full physiological model that accounts for all four factors simultaneously: air temperature, humidity, wind speed, and the mean radiant temperature from solar radiation and surrounding surfaces. In sunny, windy, or mixed conditions, the two values can differ by 10–20 °C. UTCI is the standard used in European heat-health warning systems and urban heat research.</p>

    <summary class="faq-q">Why does the sky display show the wrong time of day?</summary>
    <p class="faq-a">The sky scope always shows current conditions — it reflects the actual time right now, not the hour you are browsing in the table. The sun position, sky colour, and glow intensity are all calculated from the real solar elevation and radiation data for the current moment. If you are looking at a future or past hour in the forecast table, the sky display will not follow — it stays locked to now.</p>

PM10 covers particles up to 10 micrometres including dust, pollen, and mould spores. PM2.5 covers finer particles up to 2.5 micrometres from vehicle exhausts and wood burning. PM2.5 is more dangerous because particles penetrate deep into the lungs and enter the bloodstream. Both are included in the AQI shown in SunScope."}},

Below 10 is Low - most people notice nothing. 10-30 is Moderate - mild symptoms for sensitive sufferers. 30-80 is High - most hay fever sufferers will have symptoms. Above 80 is Very High - symptoms likely even with antihistamines. Select your specific pollen type: grass, birch, alder, mugwort, olive, ragweed, or total. In the UK grass peaks June-August; birch and alder peak in spring. Pollen is often lower after rain and in the evenings."}},

A ground frost is when the temperature at the surface falls below 0 degrees - which can happen even when air temperature is 2 or 3 degrees, because the ground radiates heat upward on clear still nights and chills faster than the air. Ground frosts damage tender plants, ice windscreens, and make paths slippery. SunScope flags frost events in the weather event banners above the table."}},

Warm-season crops like courgettes and beans need 12-15 degrees or more. Cool-season crops like lettuce can germinate at 4-5 degrees. Sowing too early into cold soil leads to seeds rotting. SunScope shows surface soil temperature and 6 cm depth temperature - the root zone where germination happens.
