utciP: { title: 'SunSoak', desc: 'SunScope\'s signature felt-temperature index. Starts from UTCI - the biometeorological standard combining air temp, humidity, wind and solar radiation - then layers in three extra dimensions: a rain and snow penalty (wet clothing can drop felt temp by up to 8 °C), an environment modifier that adjusts solar load for where you actually are (forest canopy, alpine altitude, lakeside reflection, shaded riverbank, desert ground heat), and the full radiant heat from your surroundings. One number that honestly answers: what will my body actually feel out there?' },

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.' },

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. Relevant for driving, flying, and photography.' },

aqi: { title: 'Air Quality Index', desc: 'European Air Quality Index (0–100+), combining PM2.5, PM10, ozone, nitrogen dioxide, and sulphur dioxide. 0–20 = Good; 20–40 = Fair; 40–60 = Moderate; 60–80 = Poor; 80–100 = Very Poor; 100+ = Extremely Poor. Sourced from Copernicus CAMS.' },

pollen: { title: 'Pollen', desc: 'Pollen concentration in grains per cubic metre for the selected pollen type, sourced from the Copernicus CAMS pollen forecast. Low = <10; Moderate = 10–50; High = 50–200; Very High = 200+. Values vary by species and season.' },
