Intensity depends strongly on solar elevation and cloud cover.' }, burn: { title: 'Burn Time', desc: 'Estimated time to reach one Minimal Erythemal Dose (MED) — the threshold for sunburn — based on the UV index and your selected skin type. This is a guide, not a medical measurement.' }, utciP: { title: 'SunSoak', desc: 'SunScope\'s felt-temperature index. Based on UTCI — the standard combining air temp, humidity, wind, and solar radiation — with added adjustments for rain/snow and your chosen surroundings.' }, precip: { title: 'Precipitation', desc: 'Expected rainfall or snowfall in mm per hour. Snow is shown in cm. Even light drizzle meaningfully reduces felt temperature when combined with wind.' }, precipProb: { title: 'Rain Probability', desc: 'Probability of precipitation for this hour as a percentage (0-100%). Derived from Open-Meteo ensemble model runs. A high value means rain is likely even if the expected rate is low - useful for spotting showers that the deterministic forecast may miss.' }, lightning: { title: 'Lightning Potential', desc: 'Lightning Potential Index (LPI) from Open-Meteo in J/kg. A convective energy index — values above 5 suggest moderate lightning risk, above 25 suggest high risk.' }, soilT: { title: 'Soil Temperature', desc: 'Temperature of the soil at the surface (0 cm depth). Useful for planting decisions — most seeds germinate above 7–10 °C.' }, soilT6: { title: 'Soil Temp 6 cm', desc: 'Temperature of the soil at 6 cm depth, the root zone for many crops and seedlings. Lags behind surface temperature by several hours.' }, soilM: { title: 'Soil Moisture', desc: 'Water saturation of the top 1 cm of soil as a percentage. Above 40% suggests saturated ground; below 20% indicates dry conditions.' }, concreteT: { title: 'Concrete Surface', desc: 'Estimated temperature of sun-exposed urban concrete or paving. Concrete absorbs more solar energy than grass and cannot cool itself through evaporation — surface temps can run 15–25 °C above air temperature on sunny days.' }, vehicleT: { title: 'Vehicle Interior', desc: 'Estimated ambient cabin temperature inside a parked vehicle. Cars heat rapidly through thin body panels and glass; motorhomes and caravans are modelled as insulated occupied living spaces with retained warmth, lower glass gain, and slower heat response. Dangerous for children and pets above 35 °C; potentially fatal above 45 °C.' }, indoorT: { title: 'Indoors', desc: 'Estimated ambient temperature inside a selected building type with windows closed and no air conditioning. Accounts for retained warmth, window solar gain, internal gains, and thermal lag without repeatedly accumulating solar heat hour after hour.' }, managedT: { title: 'Managed Indoors', desc: 'Estimated indoor temperature with curtains closed and windows opened when outdoor air is cooler than inside — the standard UK heatwave advice. Curtains block most direct solar gain; smart ventilation pulls the temperature down during cooler periods.' }, vis: { title: 'Visibility', desc: 'Horizontal visibility in kilometres, sourced from the CAMS air quality model. Values below 1 km indicate fog or very thick haze; below 10 km suggests mist, smoke, or significant pollution.
