Abstract
We are applying image reconstruction methods to produce a systematically reprocessed historical time series NASA MEaSUREs Earth System Data Record (ESDR), at higher spatial resolutions than have previously been available, for the 36-year satellite passive microwave record from SMMR, SSM/I-SSMIS and AMSR-E. We compare and contrast two candidate image reconstruction techniques: Backus-Gilbert interpolation (BGI) and a radiometer version of Scatterometer Image Reconstruction (SIR)
