Taberner, M, Pinty, B, Govaerts, Y, Liang, S, Verstraete, MM, Gobron, N, Widlowski, JL (2010). Comparison of MISR and MODIS land surface albedos: Methodology. JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES, 115, D05101.

The broadband white sky surface albedo (bihemispherical reflectance) products available from the Moderate Resolution Imaging Spectroradiometer (MODIS) are compared at regional and continental scales with similar products generated from the Multiangle Imaging Spectroradiometer (MISR) land surface bidirectional reflectance factor (BRF) parameters. This paper describes the methodology applied to derive MISR white sky albedos over four spectral broadbands of interest, namely, 0.3-0.7 mu m, 0.4-1.1 mu m, 0.7-3.0 mu m, and 0.3-3.0 mu m, as well as an evaluation of the strategy adopted to compare the MODIS and MISR products. The results are very encouraging since the two data sets show very good statistical agreement over large areas and over a full year of measurements, despite the many differences that exist in the suite of algorithms applied to retrieve these surface quantities from each of these instruments separately.
