Abstract :
A recent paper, J.V. Martonchik et al., IEEE Trans. Geosci. Remote Sensing, vol.36, p.1212-27 (1998), compared approximate radiative transfer results for top-of-atmosphere (TOA) radiance, using various algorithms published in the literature. We show that one of the algorithms was used incorrectly, resulting in its poor performance as stated in that paper. Correct usage produces results with errors typically less than 3%, which compares favorably to the other tested algorithms.
