One-Parameter Scaling and Exponential-Sum Fitting for Water Vapor and CO2 Infrared Transmission Functions
Publisher: American Meteorological Society
Abstract: A medium-sized band model for water vapor and CO2 absorption is developed using the one-parameter scaling approximation. The infrared spectrum is divided into 10 bands. The Planck-weighted diffuse transmittance is reduced ...
Parameterizations for Water Vapor IR Radiative Transfer in Both the Middle and Lower Atmospheres
Publisher: American Meteorological Society
Abstract: Water vapor contributes a maximum of 1°C/day to the middle atmospheric thermal infrared (IR) cooling. This magnitude is small but not negligible. Because of the small amount of mass involved and the extremely narrow molecular ...
Spectral Absorption of Solar Radiation in Cloudy Atmospheres: A 20 cm−1 Model
Publisher: American Meteorological Society
Abstract: The spectral of solar radiation in typical water clouds is determined using a radiative transfer model based on LOWTRAN transmission functions at a 20 cm?1 resolution and Monte Carlo simulations of photon pathlength ...
