Dot-dash lines connect retrievals interrupted by cloudy sky scenes while solid lines connect continuous data points. AERI spectra were supplied by the ARM program. Temperature and water vapor profiles from AERI spectra were supplied by Bob Knuteson and Wayne Feltz, U. of Wisconsin. The CO column amounts retrieved from measurements by the 3 different instruments are compared. Further improvements in algorithms and intercomparison approaches may lead to even better agreements.
Preliminary results are very encouraging.
The main objective is to further improve correlative measurement data quality and the data processing algorithm. Initial test flights of that instrument are expected in the fall of 1999 on the ER-2 aircraft. We want to thank the DOE ARM program, especially Ted Cress, Doug Sisterson, and Donald Slater, for their help in the planning and execution of Pre-MOVE at the CART site in Lamont, Oklahoma.
