The High Accuracy Atmospheric Correction for Hyperspectral Data (HATCH) model
TL;DR: An innovative technique, a "smoothness test" for water vapor amount retrieval and for automatic spectral calibration, is developed for HATCH, which includes an original fast radiative transfer equation solver and a correlated-k gaseous absorption model based on HITRAN 2000 database.

Models overestimate diffuse clear‐sky surface irradiance: A case for excess atmospheric absorption
Rangasayi N. Halthore,Seth Nemesure,Stephen E. Schwartz,Dan Imre,Alexander Berk,Ellsworth G. Dutton,Michael H. Bergin +6 more
TL;DR: In this paper, the authors show that radiative transfer models consistently overestimate surface diffuse downward irradiance in cloud-free atmospheres by 9 to 40% at two low altitude sites while correctly calculating direct-normal Solar irradiance.

Simplified atmospheric radiative transfer modelling for estimating incident PAR using MODIS atmosphere products
TL;DR: In this paper, a simplification of the general radiative transfer equations, whereby the atmosphere is modelled in a few layers depending on the opacity of the atmosphere due to clouds and aerosol load, is presented with which instantaneous photosynthetically active radiation (PAR) can be calculated with high accuracy from MODIS imagery.

TL;DR: The HITRAN molecular absorption database as mentioned in this paper contains line parameters for 31 species and their isotopomers that are significant for terrestrial atmospheric studies, including chlorofluorocarbons and other molecular species that are not amenable to line-by-line representation.

A description of the correlated k distribution method for modeling nongray gaseous absorption, thermal emission, and multiple scattering in vertically inhomogeneous atmospheres
Andrew A. Lacis,Valdar Oinas +1 more
TL;DR: A radiative transfer method for treating nongray gaseous absorption and thermal emission in vertically inhomogeneous multiple scattering atmospheres is described in this paper, where probability density distributions of absorption coefficient strength are derived from line-by-line calculations to construct line-By-line and band model based k distributions.
