            <p class="utci-about-text">
              SunScope is a free hourly weather forecast built around <strong>felt temperature</strong>,
              not just air temperature. It uses the <strong>Universal Thermal Climate Index (UTCI)</strong>
              — the biometeorological standard used in heat-health warning systems worldwide — as its
              foundation, combining air temperature, humidity, wind, and solar radiation into a single
              honest number. Then it goes further. Our <strong>SunSoak</strong> index layers three extra
              dimensions on top: a rain and snow penalty so wet, windy days read as cold as they feel;
              an <strong>environment modifier</strong> that adjusts the solar load for where you actually
              are — forest canopy, alpine altitude, lakeside glare, shaded riverbank, desert ground heat;
              and the full radiant heat absorbed from surrounding surfaces. One number that honestly
              answers: <em>what will my body actually feel out there?</em>
            </p>
            <p class="utci-about-text">
              Beyond SunSoak, SunScope calculates <strong>vehicle cabin heat</strong> (choose your
              vehicle type; toggle windows open), <strong>indoor temperature</strong> (seven building
              types including office blocks; managed heatwave mode), <strong>urban concrete surface
              temperature</strong>, <strong>UV index and sunburn time</strong> by skin type, and
              <strong>soil temperature and moisture</strong> for farming and motorhome use. Switch
              profiles — Places, Activities, Work — to see the data that matters for your situation,
              or go Custom and build your own view.

            <p class="utci-about-text">
              SunSoak is the number to watch — it reflects everything your body
              actually experiences, not just what the thermometer says. A large gap between SunSoak and Air
              temperature means solar radiation is doing significant work on your body. On clear sunny days
              that gap can exceed 10 °C even at modest air temperatures. The environment modifier in the
              SunSoak dropdown adjusts the solar load for your surroundings — switch it to match where you are
              for the most accurate reading.
