Abstract:

New laboratory measurements have been made of the H2O continuum absorption at several wavenumbers within the 700-1200 cm-1 and 2400-2800 cm-1 regions. Samples of both pure H2O and H2O N2 have been studied in a multiple-pass absorption cell at path lengths up to more than 800 meters. Data for samples of pure H2O at reduced temperatures 284 K indicate that the self-broadening coefficients increase with decreasing temperature at about the rate predicted by extrapolating from previous data on samples at elevated temperatures. Coefficients for N2 broadening have been measured in both windows, and the results compared with previous work. The results have been compared with the data base for the well-known transmission computer code LOWTRAN 6. Author
