Geosphere - Maps & Data
My NASA Data (MND) provides online resources to help teachers and students access NASA data in a variety of formats. MND offers pre-generated graphs, mapped visualizations, animations, and processed data based on NGSS phenomena, providing the learner with the opportunity to explore concepts without being encumbered by visualization interfaces. These flexible resources provide guiding questions and other teacher tools so you can use them to open or close your class activity.

Featured Phenomenon: Soil Moisture
Soil moisture is the water that is held in the spaces between soil particles, generally in the upper 10 cm of soil; this small amount of water plays a critical role in controlling the transfer of water and heat energy between Hydrosphere, Biosphere, and Geosphere.
May 2018 Soil Moisture for Continental USA
The Soil Moisture Active Passive mission (SMAP) was launched in 2015 as the first NASA satellite dedicated to measuring the water content of soils. The satellite uses a radiometer to measure soil moisture in the top 5 centimeters of the ground.
Progression of Spring Thaw
The radar measurements made by NASA's Soil Moisture Active Passive (SMAP) observatory are sensitive to whether land surfaces are frozen or thawed.
Hurricane Harvey's Effect on Soil Moisture
Hurricane Harvey dropped record-breaking amounts of rainfall, particularly around Houston, Texas on August 25, 2017.
