Analysis of Data from INTEX-A and B in Support of Aura and Aqua Validation

A Research Project for the National Aeronautics and Space Administration

Task 1 - Mission Meteorologist

Prof. Fuelberg is Mission Meteorologist during INTEX-B. He was assisted by several graduate students. Their duties are listed below.

Weather Forecasting -- The mission meteorologist prepares surface and flight level weather forecasts and provides briefings to the Science Team. Forecasting areas of clear skies was especially important during INTEX-B since the DC-8's underpasses of the Aura satellite require virtually cloud free conditions.

Meteorological Products -- Meteorological forecast products were prepared for flight planning using gridded NWS numerical model output from the NWS Global Forecast System (GFS). These included streamline and tropopause height analyses, cross sections along flight tracks, and analyses of humidity and clouds.

Trajectories -- We prepared backward trajectories that arrive along the proposed INTEX-B flight tracks. We also prepared forward trajectories from Mexico City and major population/industrial regions in Asia.

Boundary Layer Exposure Product -- We developed a procedure to isolate air that previously was within the boundary layer-the source of most pollution. The procedure rigorously defines the boundary layer using established PBL criteria. During INTEX-B we ran the procedure in real time using data from the GFS model.

Prepare Post-Mission Meteorological Products -- Now that the field phase of INTEX-B is completed, we have prepared final meteorological products (e.g., trajectories, etc.) using only observed (not forecast) data. These products are based on the actual flight tracks.

Task 2 - Integrate TES CO Data with Meteorology and with AIRS CO

TES provides CO data at very high vertical resolution. By using numerically-derived meteorological data at correspondingly fine resolution, we will seek to understand the processes that produce horizontal patterns in TES-derived CO and the temporal evolutions of those patterns. Similar research will be performed on nearly co-incident AIRS-derived CO, with comparisons made between the two versions of CO. This in-depth understanding of the two versions of CO retrievals will provide important verification of Aura and Aqua CO products. Finally, research on the trans-Pacific transport of pollution will address one of the major science issues of INTEX-B-to quantify and characterize the inflow of pollution over North America. Detailed research plans are listed below.

Methodology - Our methodology will be similar to that during INTEX-A.
