Development of Software Analysis Tools Based on Spectrocopic Data Bases such as HITRAN for Atmospheric Trace Gas Detection Lidars from Space Based Platforms
Opportunity Restricted to U.S. Citizens Only
There is a need to develop effective software analysis tools based on HITRAN and other spectroscopic data bases to predict lidar performance for atmospheric trace gas detection from space based platforms. The variation of line parameters with pressure, temperature and lineshape functions have to be accurately known for calculation of mixing ratios of a given trace gas species. The ongoing ASCENDS program at NASA Langley will benefit from these tools for accurate prediction of CO2 and oxygen mixing ratios. Practical lidar instrumentaion models can be developed by incorporating these tools to aid in refining lidar system parameters for achieving less than 0.3% accuracies in CO2 mixing ratio under various atmospheric conditions.
