The Community Collaborative Rain, Hail, and Snow (CoCoRaHS) Network is a community-based network of volunteers who measure and map precipitation in all 50 states. (local high or low air pressure, the Local Inverse Barometer (LIB) effect). In this data activity, students use NASA satellite measurements of atmospheric pressure to learn that pressure decreases with height in the atmosphere. These sites host vast troves of data from across many different subjects and disciplines. Interactive map • Modeled/predicted, Search weather data from regional climate centers.

It contains the threshold variation percentage for every weather station with at least 50 daily change measurements since 2008, and the spreadsheet tabs provide both annual and month-by-month data. Watch the Earth from a satellite’s view in space, explore data collected by citizen scientists, and monitor hazards like hurricanes, wildfires, and droughts. As well as the tides, the sea level as measured by tide gauges is locally depressed or elevated by changes in the weight of the atmosphere above the sea, (local high or low air pressure, the Local Inverse Barometer (LIB) effect). Often geared for researchers, these data resources come in a variety of formats and are not associated with lesson plans.
