THE SCATTEROMETER AS A PRESSURE SENSOR
The UW Planetary Boundary Layer (PBL) model is used to derive surface pressure fields from scatterometer surface measurements. After a decade of comparison with NMC wind products, it is clear that the combination of the scatterometer and the PBL model yield superior information about the global pres...
