During the intensive field campaigns of the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE) in May-October of 1987, several nearly simultaneous measurements were made with low-altitude flights of the L-band radiometer and C- and X-band scatterometers over two transects in the Konza Prairie Natural Res...
Radar-backscatter measurements were made to estimate soil moisture. The helicopter-mounted radar was flown along selected transects that coincided with soil-moisture measurements. The radar operated at microwave frequencies of 5.3 and 9.6 GHz and at selected incidence angles between 0 and 60 degrees. Vertical polarization was used for two days and...

... FMC is difficult to obtain over large scales. Limited success has been reported to estimate FMC by means of remote sensing using shortwave (SW) reflective, thermal and microwave data (Bowman, 1989;Carter, 1991;Gogineni et al., 1991;Chuvieco et al., 2004). The basic information content for optical remote sensing of MFC comes from the SW infrared (SWIR) reflectance around 1.6 m (Tucker, 1980;Hunt and Rock, 1989), that is available from many common sensors such as MODIS, AVHRR and VGT (Fraser and Li, 2002). ...
... To deal with the problem of measuring ET fluxes in a composite terrain, large-scale field experiments in the African continent (e.g., Sahel: Goutorbe et al., 1997;southern Africa: Otter et al., 2002), the European continent (e.g., France: Andre et al., 1986;Spain: Bolle et al., 2006), the American continent (e.g., Kansas: Smith et al., 1992;Arizona and Oklahoma: Jackson et al., 1993) and the Asian continent (e.g., China: Wang et al., 1992: Korea: Moon et al., 2003 were set up to measure fluxes simultaneously within a certain geographic region at a number of sites with different land use classes. Several remotely sensed ET algorithms were developed and validated using these data sets. ...
