Binary snow cover
WebBinary snow maps and fractional snow cover data are provided routinely from MODIS (Moderate Resolution Imaging Spectroradiometer). This paper investigates how the wide observation angles of MODIS influence the current snow mapping algorithm in forested areas. Theoretical modeling results indicate that large view zenith angles (VZA) can lead … WebApr 19, 2024 · The pixels of cloud mask were identified by the MODIS and VIIRS cloud-masking algorithms, and labeled in the snow cover products with the value of 250, and …
