BRAMS RAMSIN:

Model Input Namelist Parameters

 

This document will describe the input namelist parameters for the RAMS v.504 atmospheric model with developments for BRAMS project, including CATT - Coupled Aerosol and Tracer Transport and TEB - SPM – Town Energy Budget – Simple Photochemical Module - emission models (developed in CPTEC/INPE and IAG/USP – Brazil), and the RAMS ISAN (ISentropic ANalysis) package.

Specifying values for each of the variables in the atmospheric model namelists is the principal way that a user sets up the desired model configuration and selects the many options available for a particular model run. The namelists have the appearance of a standard FORTRAN namelist, and indeed they were patterned after the FORTRAN format. However, there have been several deficiencies in the FORTRAN standard, even in FORTRAN 90, concerning namelists. The biggest deficiency is a complete lack of, or different formats for, comments. Therefore, early in RAMS development, a replacement for the standard FORTRAN namelist reading capability was developed.
