This technical report presents recent effort to compute variograms using a spectral method. Variograms are used to compute the sampliing uncertainty of the 1°/1 day rainfall amount of the TAPEER product. The document is available here: Megha-Tropiques Technical Memorandum n°7.
Layer-averaged Relative Humidity profiles are now available on the ICARE data center since the launch of the Megha-Tropiques satellite. This product decomposes the troposphere into 6 layers: 100-200hPa, 250-350hPa, 400-600hPa, 650-700hPa, 750-800hPa and 850-950hPa. The retrieval scheme named ARPIA for « Atmospheric Relative…
