The broadband white sky surface albedo (BiHemispherical Reflectance) products available from the MODerate resolution Imaging Spectroradiometer (MODIS) are compared, in joint papers, at regional and continental scales with similar products generated from the Multiangle Imaging SpectroRadiometer (MISR) land surface Bidirectional Reflectance Factor (BRF) parameters. This first 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 datasets are showing 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. Large scale analyses of the two MODIS and MISR-derived products have been conducted and results are shown and discussed in a companion paper (Part II).
