We present a new method to estimate sea ice concentration in the Arctic Ocean using brightness temperature observations from the Soil Moisture Ocean Salinity (SMOS) interferometric satellite. ...
We therefore argue that SMOS estimates can be a compelling complement to estimates of ice concentration of both thick and thin sea ice from other satellite sensors such as the Advanced Microwave Scanning ...

Two approaches to the alerting of windshear have been studied, namely, the calculation of Brunt-Vaisala frequency and the standard deviation of the brightness temperature measured by a microwave radiometer ...
The former tries to represent the stability of the boundary layer of the atmosphere (terrain-induced windshear tends to occur in stable boundary layer) and the latter tries to correlate the wind fluctuations ...
