L-band Radiometer Calibration Consistency Assessment for the SMOS, SMAP and Aquarius Instruments
[10-Jul-2016] Dinnat, E. and Le Vine, D.
Presented at the 2016 International Geoscience and Remote Sensing Symposium
Three L-band radiometers have been observing the Earth in order to retrieve soil moisture and ocean salinity. They use different instrument configurations and calibration and retrieval algorithms. In any case, the brightness temperature retrieved at the Earth surface should be consistent between all instruments. One reason for inconsistency would be the use of different approaches for the instrument calibration or the use of different models to retrieve surface brightness temperature. We report on the different approaches used for the SMOS, SMAP and Aquarius instruments and their impact on the observations consistency.
