These Moderate-resolution Imaging Spectroradiometer (MODIS) false-color images show the total area in North America covered by snow (white pixels) as compared to the 35-year average snowline (red line). Each image represents an 8-day composite for the periods November 1–7, 8–18, and 16–23, 2001. The light gray pixels show areas that were covered by clouds for the entire 8-day period. The green pixels are land regions without snow, blue pixels represent water, and dark gray shows where no data were collected.
