This map in ArcGIS Online shows snow cover for the globe as it changes throughout the course of the year. The patterns the map reveals is fascinating. What is the effect of latitude on snow cover? How does snow cover in the Northern Hemisphere compare to that in the Southern Hemisphere? Which month had more snow on the ground than any other, in Canada, versus in Sweden? What is the effect of elevation on snow cover? During a specific month, which of the world's major cities had snow on the ground? Measure the extent in square kilometers for each of the months for specific countries and graph your results.
This map features NASA’s Next Generation Blue Marble imagery in a set of 12 monthly composite images of the entire earth, using 500-meter-resolution imagery from the MODIS satellite. More information is available than just the snow cover. These monthly images reveal other seasonal changes on the land surface, such as the greening up and dying back of vegetation in the temperate regions such as North America and Europe, and the dry and wet seasons in the tropics. The Blue Marble Next Generation imagery was produced by Reto Stöckli, NASA Earth Observatory (NASA Goddard Space Flight Center). The data is from 2004. For more information about this data layer, see this description. The data layer can be added to any map that you are analyzing in ArcGIS Online, and compared to other data layers, such as mean annual precipitation, or ecoregions. If you prefer to show the data as a web mapping application, see this app.
