Abstract
Singh, in a recent paper, attempts to describe the effect of sea surface emissivity variations on sea surface temperature (SST) retrieval from satellite borne infrared instruments (specifically the Along Track Scanning Radiometer (ATSR)). It is based, for the most part, on an incorrect premise, draws conclusions about SST retrieval accuracy which are not supported by the necessaryevaluation of atmospheric and retrieval algorithm effects, and contains erroneous calculations. The shortcomings of the paper are discussed.
