Color contour plots of deepp layer mean steering products, available for 700-850 mb, 500-850 mb, 400-850 mb, 300-850 mb, 250-850 mb, and 200-700 mb layers. A detailed description of the CIMSS atmospheric motion vector based deep layer mean steering product can be found here.

 

 
McIDAS Format MD Files These files contain our atmospheric motion vector products stored in McIDAS MD file format.
 
Text Files These files contain our atmospheric motion vector products in digital text format. The "all winds" files include all atmospheric motion vectors regardless of location. The "ocean only" files include only those motion vectors over water. We have basic text files and text files that include some quality control information, CIMSS RFF with EUMETSAT QI and CIMSS RFF, EUMETSAT QI, and Expected Error.
