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 data to determine the seasonal cloud coverage and the occurrence of different cloud types, by percent, in North Carolina (or their local area). Students will identify different cloud types and determine their seasonality. They will graph the data and explore whether there is a correlation between season, cloud cover and type of cloud most prevalent during each season. The lesson provides detailed procedure, related links and sample graphs, follow-up questions and extensions, and Teacher Notes. Educational levels: High school
