Abstract : An existing Fourier Transform Spectrometer (FTS) data base of slant path atmospheric transmission spectra using the sun as a source is described. Recent improvements to the FTS measurements system are discussed and results of pyroelectric radiometer measurements of slant path solar transmission are reviewed. Techniques for atmospheric absorbing gas vertical density profile extraction are presented and results of model comparisons with FTS data are reviewed. Recent measurements of H2O, N2O, THC, CH4, O3, and CO2 atmospheric concentrations at the ARKY and NOP sites at WSMR are presented and discussed. Results of aerosol particulate distribution and mass loading measurements at the WSMR-NOP sites are presented and described.
