Field campaigns were undertaken in May and June of 1992 and 1997 in order to study spectral re¯ectance characteristics of snow during melt-o. The investigations were performed on snow-covered tundra at Ny-A Ê lesund, Svalbard (798N). Spectral measurements were acquired with spectroradiometers coveri

✦ Synopsis
The remote sensing community puts major efforts into calibration and validation of sensors, measurements, and derived products to quantify and reduce uncertainties. Given recent advances in instrument design, radiometric calibration, atmospheric correction, algorithm development, product development, validation, and delivery, the lack of standardization of reflectance terminology and products becomes a considerable source of error. This article provides full access to the basic concept and definitions of reflectance quantities, as given by Nicodemus et al. [Nicodemus, F.E.,
