Meteorological effects and impacts of the 10 June 2021 solar eclipse over the British Isles, Iceland and Greenland.

The beginning, peak and end of the eclipse are marked as in Figure 4. gl Surface air temperature averaged from 254 MMS sites shows a marked reduction in the rate of increase of temperature around the time of peak eclipse (Figure 6a). In addition, the maximum and minimum temperatures recorded every 10min were also available for many of these sites, so we were alternatively able to quantify the temperature decrease based on the highest temperature between 0830 and 0930 utc (near the start of the eclipse) and the lowest temperature between 1000 and 1100 utc (around the eclipse peak). Iceland Conditions here too were generally cloudy during the eclipse (Table S3), but the eclipse magnitude was much larger than over the British Isles, being typically ~70% magnitude or ~60% coverage of the solar disk at peak eclipse (Figure 1). Also, all of the nine sites with relatively less cloud cover had significant changes in cloud cover during the eclipse, so were not a suitable subset to use for studying the eclipse influence on surface air temperature.
