Arctic Research of the Composition of the Troposphere from Aircraft and Satellites
Chemical Forecasts for ARCTAS using MOPITT and MODIS measurements and the Community Atmosphere Model with Chemistry (CAM-Chem)
We will be supporting the NASA Arctic Research of the Composition of the Troposphere from Aircraft and Satellites ( ARCTAS ) campaign with a combination of model simulations and satellite observations. The Spring Phase of ARCTAS will be April 1-21, based in Fairbanks, AK. The Summer Phase includes DC8 flights from Palmdale, CA, June 18-25, and from Cold Lake, Alberta, June 26-July 14, 2008.
Retrievals of carbon monoxide (CO) from observations by Terra/ MOPITT will be produced in near-real-time. Chemical forecasts will also be produced using Ensemble Kalman Filter Data Assimilation of meteorological observations, MOPITT CO, and MODIS aerosol optical depth (AOD) with the NCAR Community Atmosphere Model with Chemistry (CAM-Chem). CAM-Chem is a component of the NCAR CCSM . The data assimilation will be performed in the Data Assimilation Research Testbed ( DART ) framework. Forecasts will also be run with MOZART-4 driven by NCEP/GFS meteorology.
