WebThe bias between the different satellites from the GRC that were relative to the IAACs, had a mean bias of about −0.4 to 0.5 ns in 2008, while the bias varied between −0.3 and 0.3 ns … The purpose of this paper is to assess the problem of TEC bias of altimeters. Two approaches have been followed. The first one relied on the TEC data series of the four altimeters to determine inter-mission systematic biases using the last available data versions for each mission.
