       <tr id="col-sun"><td><strong>Sun °</strong></td><td>The angle of the sun above the horizon in degrees. Below 0° the sun has set. The higher the elevation, the more intense the radiation reaching the ground.</td></tr>
       <tr id="col-direct"><td><strong>Direct W/m²</strong></td><td>Shortwave solar radiation arriving as a direct beam from the sun. The primary driver of skin heating on sunny days.</td></tr>
       <tr id="col-diffuse"><td><strong>Diffuse W/m²</strong></td><td>Solar radiation scattered from all directions across the sky. Present even under cloud cover; contributes to the overall solar heat load.</td></tr>
-      <tr id="col-tmrt"><td><strong>Tmrt °C</strong></td><td>Mean Radiant Temperature — the combined heat from direct sun, scattered sky light, and ground reflection expressed as a temperature. Can exceed air temperature by 20–30 °C on a sunny day; this is why shade feels so much cooler, and it is one of the inputs to UTCI.</td></tr>
-      <tr id="col-delta"><td><strong>UTCI−Air Δ</strong></td><td>The gap between the UTCI felt temperature and the plain air temperature. A large positive value means solar radiation is adding significant heat stress beyond what the thermometer shows.</td></tr>
       <tr id="col-utci"><td><strong>UTCI °C</strong></td><td>Universal Thermal Climate Index — the peer-reviewed standard felt temperature, combining air temp, humidity, wind, and solar radiation. Always computed from the raw open-ground reading: it does not move when you change the Solar Model, and it excludes precipitation. That is deliberate — it is the fixed benchmark to read SunSoak against, so the gap between the two shows exactly what your surroundings and the weather are adding.</td></tr>
       <tr id="col-uvA"><td><strong>UV-A</strong></td><td>Estimated UV-A radiation index. UV-A penetrates deeper into the skin and contributes to long-term ageing and some skin cancers, even through glass. Present throughout daylight hours.</td></tr>
       <tr id="col-uvB"><td><strong>UV-B</strong></td><td>Estimated UV-B radiation index. Causes sunburn and drives vitamin D production. Intensity depends strongly on solar elevation and cloud cover, falling sharply at low sun angles.</td></tr>

       <tr id="col-utciP"><td><strong>SunSoak °C</strong></td><td>SunScope's signature felt-temperature index. Starts from UTCI then adds three layers: a rain and snow penalty (wet clothing can drop felt temperature by up to 8 °C), a Solar Model for where you actually are (forest, alpine, beach, river, open water, desert), and full mean radiant temperature from surrounding surfaces. The most honest single answer to: what will it actually feel like out there?</td></tr>
       <tr id="col-shadeT"><td><strong>Shade °C felt</strong></td><td>SunSoak with the sun taken away — the felt temperature standing in the typical shade of the selected Solar Model (building shadow, beach umbrella, tree canopy, boat panels, and so on). You are still outdoors, so wind, humidity and rain affect you exactly as they do in the open; only the direct beam and part of the sky are blocked. Expect several degrees below SunSoak in daytime sun, and near-identical readings after dark, when there is no sun to stand out of.</td></tr>
       <tr id="col-precip"><td><strong>Precip mm</strong></td><td>Expected rainfall in mm per hour; snowfall is shown in cm. Even light drizzle meaningfully reduces felt temperature when combined with wind.</td></tr>
-      <tr id="col-precipProb"><td><strong>Rain %</strong></td><td>Probability of precipitation for this hour (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 the deterministic forecast may miss.</td></tr>
-      <tr id="col-lightning"><td><strong>Lightning</strong></td><td>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.</td></tr>

A high value means rain is likely even if the expected rate is low — useful for spotting showers the deterministic forecast may miss. A ⚡ beside the percentage marks a thundery hour, driven by the Lightning Potential Index (LPI) from Open-Meteo: it appears above 5 J/kg (moderate risk) and turns bold above 25 (high risk), with the cell tinted amber either way.</td></tr>
       <tr id="col-soilT"><td><strong>Soil °C surface</strong></td><td>Temperature of the soil at the surface (0 cm depth). Most seeds germinate above 7–10 °C. Useful for sowing decisions and frost assessment.</td></tr>
       <tr id="col-soilT6"><td><strong>Soil °C 6 cm</strong></td><td>Soil temperature at 6 cm depth — the root zone for many crops and seedlings. Lags behind the surface by several hours.</td></tr>
       <tr id="col-soilM"><td><strong>Soil moisture</strong></td><td>Water saturation of the top 1 cm of soil as a percentage. Above 40% indicates saturated ground; below 20% is dry. Useful for assessing whether ground is workable, and for motorhome or caravan pitch suitability.</td></tr>
