Atmospheric Composition Research using Observations from SATellites

About the project

 Within ACROSAT satellite measurements (by GOME-2 and current ESA’s Third Party Missions) will be used in synergy with ground-based data and atmospheric models in order to investigate issues in the chemistry and composition of the atmosphere.

 

 

ACROSAT aims in particular to quantify and possibly explain the spatial distributions and long-term changes in the abundance of key compounds participating in stratospheric ozone depletion (e.g. HCl), tropospheric ozone formation (NOx, hydrocarbons) and aerosol formation in the stratosphere (OCS) and in the troposphere (SO2, hydrocarbons).

Another goal of this project is to better characterize the diurnal cycle of short-lived compounds (NO2, HCHO, glyoxal) and its impact on the accuracy of satellite Level-2 retrievals. It will provide inputs to Protocol monitoring and it will support the ESA Climate Change Initiative.

The project runs through 2014-2015.
