SSM/I Surface Winds Statistics Archive


Here statistics which compare NCEP Operational1 SSM/I Neural Network Algorithm (OMBNN3)
and Shared Processing Project Operational Algorithm (SPP) are accumulated.

Global Statistics (Bias & RMSE); +/- 1 hour temporal window and +/- 50 km spatial window
were used to create buoy SSM/I collocation.
All statistics are calculated using real time buoy data which are not quality controlled!!!


 Images in This Table Show Wind Speed Bias and RMSE (in m/sec).
