—In support of the European Space Agency Soil Moisture and Ocean Salinity (SMOS) mission, a number of soil moisture and sea salinity campaigns, including airborne L-band radiometer measurements, have been carried out. The radiome-ter used in this context is fully polarimetric and has built-in radio-frequency-interference (RFI)-detection capabilities. Thus,… (More)
investigate open questions including the sun-glint effect over land, the application of polarimetric measurements over land, and to clarify the importance of dew and interception for soil moisture retrievals. This paper summarises the campaign activities, and presents progress on the analysis of the CoSMOS data set.
A number of experimental campaigns, including airborne L-band radiometer measurements, have been carried out in support of ESA's Soil Moisture and Ocean Salinity (SMOS) mission. The radiometer used in this context is fully polarimetric and has built-in Radio Frequency Interference (RFI) detection capabilities. Thus the instrument, in addition to providing… (More)
soil moisture data obtained from SMOS. However, comparisons with SMOS observations for the campaign period indicate severe differences between simulated and observed SMOS data.
ESA has assigned the Technical University of Denmark to develop an airborne P-band ice sounding radar demonstrator. 1 The intention is to obtain a better understanding of the electromagnetic properties of the Antarctic ice sheet at P-band and to test novel ice sounding techniques in preparation for a potential spaceborne ice sounding radar. The airborne… (More)
RFI (radio frequency interference) is a possible threat to coming spaceborne L-band radiometer missions. Ground based and airborne campaigns report some level of interference that must be detected and possibly mitigated. Methods to do so are discussed and demonstrated.
