Summaries added — every column in COL_DESCRIPTIONS got a short (1–2 sentences) and a link to its reference row. Full desc text kept intact for the day-tab metric labels. Popup rewired — renders the summary plus a "More about this column →" link, opening in a new tab. Link styling — .col-info-more pinned below the summary so it stays visible if the text scrolls; centred on mobile with the rest. Anchors on the reference page — 35 row ids in columns.html, one per column key. New "Rows" row — the hour/interval header had a popup but no matching row on the reference page; added. Landing highlight — tr:target gets a gold bar and tint, with scroll offset so the nav doesn't cover it.

<h1>About SunScope</h1>
|
|
<p class="tagline">See the sun the way your skin does.</p>
|
|
|
|
<h2>What is SunScope?</h2>
|
|
<p>
|
|
SunScope is a free outdoor thermal comfort forecast that goes well beyond standard air
|
|
temperature. Most weather apps tell you it's 12 °C and leave you to guess whether that means
|
|
a t-shirt or a heavy coat. SunScope combines air temperature, humidity, wind speed, and solar
|
|
radiation into a single <strong>felt temperature</strong> — so you know what to actually expect
|
|
when you step outside.
|
|
</p>
|
|
<p>
|
|
The core calculation is the <strong>Universal Thermal Climate Index (UTCI)</strong>, a
|
|
peer-reviewed biometeorological standard developed by
|
|
<a href="https://utci.org/" target="_blank" rel="noopener noreferrer">Bröde et al. (2012)</a>
|
|
and used globally in heat-health warning systems. On top of that, SunScope builds its own
|
|
<strong>SunSoak</strong> index — layering a rain and snow penalty, a <strong>Solar Model</strong>
|
|
that adjusts the solar and thermal load for your surroundings, 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>
|
|
Forecast data is sourced in real time from <strong>Open-Meteo</strong>, a free and open-source
|
|
weather API drawing on ECMWF and national meteorological services, with air quality, visibility,
|
|
and pollen from the Copernicus CAMS forecast. The forecast refreshes automatically every five
|
|
minutes and is available for any location worldwide.

forecast.

What SunSoak is and how it's built on top of UTCI — the precipitation penalty, the Solar Model

<h2>Frequently asked questions</h2>
|
|
<p>
|
|
Got a specific question — about UTCI, the SunSoak index, UV and sunburn times, how hot a
|
|
parked car or pavement really gets, keeping your home cool without air conditioning, air
|
|
quality, pollen, or soil and farming data? Our dedicated
|
|
<a href="./faq.html">FAQ page</a> answers the most common questions in plain language, grouped
|
|
by topic.
