• Evidence for RFI in SMOS data — by Niels Bormann — last modified Oct 15, 2010 10:40 AM Standard deviations of brightness temperature first guess departures [K] for 1-7 March 2010 for the SMOS channel 2, taken from the ECMWF system (courtesy of Joaquin Munoz Sabater, ECMWF).
• Spot beams of DirecTV satellite transmissions — by Niels Bormann — last modified Oct 15, 2010 10:38 AM Example footprints of DirecTV-12 spot beams. Each solid contour line corresponds to a -8 dB antenna gain (relative to the maximum gain in the center of the footprint). Courtesy of Blazej Krzeminski, ECMWF.
• RFI in AMSR-E data — by Niels Bormann — last modified Oct 15, 2010 10:40 AM Geographical distribution of average AMSR-E 18.7 GHz all-sky background departures for glint angles lower than 20 degrees (a,b) and larger than 20 degrees (c,d). Statistics were calculated over the period 7 August - 30 September 2008 from the ECMWF assimilation system. Courtesy of Blazej Krzeminski, ECMWF.
