University of Wisconsin Direct Broadcast CRAS Page  

This page shows animations of the most recent run of the International MODIS/AIRS Processing Package (IMAPP) Direct Broadcast CIMSS Regional Assimilation System Forecast Model centered on Madison, Wisconsin. CRAS is a numerical weather prediction model that is unique in its ability to assimilate satellite products in order to improve the initial conditions used in the model forecast physics. This version of the CRAS has been modified to use Aqua and Terra IMAPP MODIS mod07.hdf (atmospheric profiles) and mod06ct.hdf (cloud top properties) products to improve the depiction of clouds and moisture in the Global Forecast System (GFS) grid fields.
