May 2024’s average mean temperature of 13.1°C for the UK beat 2008’s previous record figure of 12.1°C in a series which dates back to 1884. The month’s mean temperature has been influenced particularly by above average temperatures in the northern half of the UK, with Scotland’s May mean

the solar wind in-situ The Parker spiral Image credit: I. Mueller-Wodarg There are different types of solar wind • Fast solar wind (v≈750km/s) comes from coronal holes • At solar minimum, polar coronal holes dominate flow – fast wind over the Sun’s poles • Slower (v≈400 km/s), denser (≈2x) and more

and chloroform emissions, together with ozone and hydrogen deposition have been characterised, leading to the estimation of methane emission rates for each event. The mean methane emission flux was found to be 400 ± 90 ng m - 2 s -1 . A strong seasonal cycle was found in the methane emission fluxes

Over the past 10 years, meteorologists around the world have been increasingly tapping into data that is routinely communicated between aircraft and air-traffic control called Mode-S EHS.

with others to collect and share these data with our partners across Europe. Through a new intiative, this work will be expanded to capture much more weather data from aircraft flying in other parts of the world. We are working with Flightradar24, who already have a global network of MODE-S receivers
