Traffic density, wind and air stratification influence concentrations of air pollutant NO2
Traffic density is the most important factor for much the air pollutant nitrogen dioxide (NO2). However, weather also has an influence, according to a new study, which evaluated the influence of weather conditions on nitrogen dioxide concentrations in Saxony 2015 to 2018. It was shown that wind speed and the height of the lowest air layer are the most important factors that determine how much pollutants can accumulate locally.

New 'sun clock' quantifies extreme space weather switch on-off
Extreme space weather events can significantly impact systems such as satellites, communications systems, power distribution and aviation. They are driven by solar activity which is known to have an irregular but roughly 11 year cycle. By devising a new, regular 'sun clock', researchers have found that the switch on and off of periods of high solar activity is quite sharp, and are able to determine the switch on-off times.
