A C-Band Scatterometer Simultaneous Wind/Rain Retrieval Method

Backscatter Variability Observed in C-Band and Ku-Band Scatterometer Data

The backscatter from ocean waves measured by scatterometers is primarily determined by the speed and direction of near-surface wind, while other influences (temperature, salinity, swell, etc.) appear to be secondary effects. A complete theoretical geophysical model, incorporating all influences on the backscatter, appears beyond the current state of science; empirical estimates of the wind-back...

Quality Control of Ku-band scatterometer winds

Support Vector Regression for Retrieval of Soil Moisture Using Bistatic Scatterometer Data at X-Band

An approach was evaluated for the retrieval of soil moisture of bare soil surface using bistatic scatterometer data in the angular range of 200 to 700 at VVand HHpolarization. The microwave data was acquired by specially designed X-band (10 GHz) bistatic scatterometer. The linear regression analysis was done between scattering coefficients and soil moisture content to select the suitable incide...

Azimuthal modulation of C-band scatterometer σ0 over Southern Ocean sea ice

In a continuing evaluation of the ERS-1 C-band scatterometer as a tool for studying polar sea ice, we evaluate the azimuthal modulation characteristics of Antarctic sea ice. ERS-1 AMI scatterometer mode data sets from several study regions dispersed in the Antarctic seasonal sea ice pack are evaluated for azimuthal modulation. When appropriate, the incidence angle dependence is estimated and re...

Probabilistic Fusion of Ku - and C-band Scatterometer Data for Determining the Freeze/Thaw State

A novel sensor fusion algorithm for retrieving the freeze/thaw state from scatterometer data is presented: it is based on a probabilistic model, a variant of the Hidden Markov model, and it computes the probability that the landscape is frozen, thawed, or thawing for each day. By combining Ku and C band scatterometer data, the distinct backscattering properties of snow, soil and vegetation at t...
