The Havemann-Taylor Fast Radiative Transfer Code (HT-FRTC): A multipurpose code based on principal components

Autor: Jonathan P. Taylor, Jean-Claude Thelen, R. Chawn Harlow, Stephan Havemann

Publikováno v: Journal of Quantitative Spectroscopy and Radiative Transfer. 220:180-192

The HT-FRTC can be used across the electromagnetic spectrum from the microwave through to the ultraviolet to calculate transmittance, radiance and flux spectra, which are represented by their principal components. The code uses monochromatic calculat
