Basis: results from winds derived from the Meteosat Satellite


Arctic Zone winds derived from the Terra Satellite

Comparison of first image targeting with middle image targeting both using the NOGAPS model


Arctic Zone winds derived from the Terra Satellite

Comparison of first image targeting and NOGAPS model with middle image targeting and GFS model.



Comparison of NESDIS and CIMSS Arctic Winds

Both use middle image targeting from the Terra Satellite along with the GFS model

From June 3rd, 2004


Comparison of NESDIS and CIMSS Antarctic Winds

Both use middle image targeting from the Aqua Satellite along with the GFS model

From June 3rd, 2004


Arctic Zone winds derived from the Terra Satellite

Verification that the changes made to the Test winds program in an effort to cross the day boundary do not cause them to deviate significantly from the previously running CIMSS wind program. Both Programs use Middle image targeting and the GFS model.



Arctic Zone winds derived from the Terra Satellite

Verification that the changes made to the Test winds program in an effort to cross the day boundary do not cause them to deviate significantly from the previously running NESDIS wind program. Both Programs use Middle image targeting and the GFS model. Comparisons only made for the wind sets not previously compaired. These are the Windsets within aproximatly 100 minutes of the day boundary.

Arctic Zone winds derived from the Terra Satellite

Comparison of the CIMSS winds program with a Test winds program that corrects for diferences in the parallax of the different satellite passes. Both Programs use Middle image targeting and the GFS model.

Arctic Zone winds derived from the Terra Satellite

Comparison of the IR with the WV winds from two differnt programs. Both Programs use Middle image targeting and the GFS model.




Arctic Zone winds derived from the Terra and Aqua Satelites

Comparison of the winds from two different satelites. Both Programs use Middle image targeting and the GFS model.
