My project is about looking at column HCHO observed from OMI, and comparing this data to what the CMAQ model believes to be present in the HCHO column. I will do calculations to determine how well CMAQ is predicting the HCHO column from OMI. For starters, I am going to look at the first few weeks in August 2007, and I may be able to expand this to other periods, or even a full summer as the project progresses
