MY NASA DATA: Comparisons of Snow Cover on Different Continents DLESE Reviewed Collection
This lesson is designed to help students gain knowledge in using the MY NASA DATA Live Access Server (LAS) to specify and download a microset of data, then to use the those data to estimate percentage of snow cover for each continent. The data used in this lesson come from the International Satellite Cloud Climatology Project (ISCCP). ISCCP computes fractional snow and ice coverage by scanning the Earth using visible, infrared and microwave imagery. Using the LAS, students will create maps of the snow cover of each continent for a particular date. They will then compare the graphical image with the text file for that map. From that information they will estimate the percentage of snow cover for each continent, and determine the average global snow cover for the selected date. The lesson provides detailed procedure, related links and sample graphs, follow-up questions and extensions, and Teacher Notes. It also includes an Excel file to help with the calculations.
