New data, based on observations from the Copernicus Sentinel-5P satellite, are showing strong reductions in nitrogen dioxide concentrations over several major cities across Europe – including Paris, Madrid and Rome.

On March 17th, the lead PIs of ACCLIP (Asian summer monsoon Chemical and Climate Impact Project) made the decision to postpone the ACCLIP airborne field campaign from summer 2020 to 2021. The airborne field campaign was jointly funded by the NSF and NASA, and involves both the NCAR research aircraft Gulfstream V and the NASA research aircraft WB-57. This decision was forced by the global COVID-19 outbreaks.

In February, we showed a drop in nitrogen dioxide (NO2) levels over China as a result of the coronavirus quarantine. New data from the European Space Agency (ESA) now show drops in NO2 concentrations over Italy due to that country’s nationwide lockdown. The change is particularly evident in the Pro Valley of northern Italy.
