Abstract:

The propagation of microwaves and millimeterwaves through the disturbed atmosphere is affected by molecular absorption that can be significantly different than the absorption in the ambient atmosphere. This is due to two factors. First, the constituents of the ambient atmosphere will exhibit significantly different electromagnetic properties at elevated temperatures. Second, many additional species that are strong absorbers of microwaves, such as HNO3, HNO2, O3, NO2, H202, OH, and N20, are present in the disturbed atmosphere. This work addressed both of these issues. A preliminary version of a code that utilized the previously available molecular data base was written in a form that would be compatible with NORSE. This code was turned over to PRi the keeper of the NORSE code and is currently being integrated into it. In addition, measurements to 1000K were made on one transition of H20 as a check on the extrapolation to higher temperature that was used in this code.
