Re: parameter values
Thank you for reaching out. NDSI_Snow_Cover is the the snow cover map with cloud and other masks overlaid. The NDSI value is scaled to the 0 - 100 range and was converted to byte from float datatype. All NDSI <= 0 are set to 0. Any pixel failing one or more of the data screens is set to 0 or other n...

Re: MODIS: Limitations of Visible Bands
MODIS is an optical sensor, which has inherent limitations in observing sea ice and snow. Unlike a passive-microwave sensor, which can detect microwave energy through clouds, MODIS cannot observe the surface when cloud cover is present. MODIS products, therefore, have cloud masks built into the data...

Re: MODIS: Choosing between Aqua and Terra products
Because MODIS sensors have flown on both the Terra and Aqua satellites, NSIDC offers parallel products derived from MODIS on each satellite. Terra and Aqua products are very similar with a few key differences: Terra launched two years before Aqua, so the Terra record starts earlier, with observation...
