Global Seasonal Mountain Snow Mask from MODIS MOD10A2

<p>Seasonal Mountain Snow (SMS) mask derived from MODIS MOD10A2 snow cover extent and GTOPO30 digital elevation model produced at 30 arcsecond spatial resolution.</p> <p>Three datasets are provided: the Seasonal Mountain Snow mask (MODIS_mtnsnow_classes), a seasonal snow cover classification (MODIS_snow_classes), and cool-season cloud percentages (MODIS_clouds). The classification systems are as follows:</p> <p>MODIS_snow_classes:</p> <ul> <li>0: Little-to-no snow</li> <li>1: Indeterminate due to clouds</li> <li>2: Ephemeral snow</li> <li>3: Seasonal snow</li> </ul> <p>MODIS_mtnsnow_classes:</p> <ul> <li>0: Mountains with little-to-no snow</li> <li>1: Indeterminate due to clouds</li> <li>2: Mountains with ephemeral snow</li> <li>3: Mountains with seasonal snow</li> </ul> <p>MODIS_clouds</p> <ul> <li>0: &lt; 5% of clouds during the cool season (defined Oct.-Mar. for Northern Hemisphere and Apr.-Sep. for Southern Hemisphere)</li> <li>1: 5% cool-season days with cloud cover</li> <li>2: 10% cool-season days with cloud cover</li> <li>3: 20% cool-season days with cloud cover</li> <li>4: 30% cool-season days with cloud cover</li> <li>5: 40% cool-season days with cloud cover</li> <li>6: 50% cool-season days with cloud cover</li> </ul> <p>&nbsp;</p> <p>For manuscript &quot;Characterizing biases in mountain snow accumulation from global datasets&quot; submitted to WRR</p>
