Atmospheric Composition REmote Sensing and Prediction

ACRESP logo

The Atmospheric Composition Remote Sensing & Prediction (ACRESP) group connects satellite observations and chemistry modeling to improve air quality forecasting. 

The ACRESP group is currently working on several projects:

  • Analysis of retrievals from MOPITT and IASI carbon monoxide (CO)
  • Development of data assimilation of satellite retrievals of chemical composition (MOPITT CO, IASI CO and O3, MODIS AOD)
  • Development of geostationary satellites (GEO-CAPE, CHRONOS)
The CHRONOS mission
  • Real-time chemical forecasts and customized forecasts in support of field campaigns

Quantifying fire emissions and associated aerosol species using assimilation of satellite carbon monoxide retrievals

Observations from a Grim Indonesian Fire Season

In September and October 2015, tens of thousands of fires sent clouds of toxic gas and particulate matter into the air over Indonesia. “The 2015 Indonesian fires produced some of the highest concentrations of carbon monoxide that we have ever seen with MOPITT,” said Helen Worden, a scientist in the ACRESP group. Average carbon monoxide concentrations over Indonesia are usually about 100 parts per billion. In some parts of Borneo in 2015, MOPITT measured carbon monoxide concentrations at the surface up to nearly 1,300 parts per billion.
