ALBDF
Absorption Line Blackbody Distribution Function
Welcome to BYU's website for our research regarding the absorption line blackbody distribution function (ALBDF). This function is used in the SLW model and other global gas radiation models.

Subroutines

The computer code (written in C++) listed below demonstrates calculating the ALBDF at sample conditions using both the correlation and the tabulated data.
