Replace em-dashes in user-facing copy across the server-rendered pages, static frontend views, and the strings the app injects at runtime, using colons, commas, parentheses or full stops as the context wants. Data placeholder glyphs (a lone "—" for a missing reading) are left alone, since a hyphen there reads as a minus sign in temperature columns. Also tighten the high-visibility surfaces (home hero and meta, about, privacy, city and records ledes, glossary blurbs) toward a plainer, more direct voice while keeping every factual claim intact.

<h1>About Thermograph</h1>
|
||
<p class="lede">Thermograph answers one question for any point on Earth: <b>how unusual is this
|
||
weather?</b> Instead of an absolute temperature, it shows where a day falls in that exact
|
||
location's own climate history.</p>
|
||
|
||
<h2>Where the data comes from</h2>
|
||
<p>The ~45-year daily record (high, low, feels-like, humidity, wind, gust and precipitation)
|
||
comes from the <b>ERA5 reanalysis</b> (ECMWF), served via <a href="https://open-meteo.com/" rel="nofollow">Open-Meteo</a>.
|
||
Because reanalysis is a gridded, model-consistent record, Thermograph works even where there's
|
||
no weather station, anywhere on the ~4 sq mi grid.</p>
|
||
|
||
<h2>How a day is graded</h2>
|
||
<p>For each metric and date, Thermograph builds a reference distribution from every historical day
|
||
within <b>±7 days of that day-of-year</b>, a 15-day seasonal window across all years. The
|
||
observed value is placed on that distribution as an <a href="{{ base }}/glossary/percentile">empirical
|
||
percentile</a>, then mapped to a grade from “Below Normal” through “High” to “Near Record”.</p>
|
||
<p>Everything is <b>relative to the location</b>: a {{ temp(60) }} day can be “Above Normal” in one place and
|
||
“Below Normal” in another. Precipitation is graded only among days that actually rained, so “Heavy”
|
||
means heavy for a rainy day <i>here</i>. See the <a href="{{ base }}/legend">grade guide</a> for the full scale.</p>
|
||
|
||
<h2>Freshness</h2>
|
||
<p>The historical archive updates as new days are added; recent and forecast conditions refresh hourly.
|
||
City climate pages show the latest recorded day graded against the local normal.</p>
