Sensing Soil Moisture with SMAP

NASA’s Soil Moisture Active Passive (SMAP) satellite launched on January 31, 2015, and measures global surface soil moisture and freeze-thaw state in the top 5 cm of soil. In this image, blue and green areas indicate higher soil moisture; yellow areas indicate lower soil moisture.

Effects of the Asian Monsoon

Monsoon season in India is officially underway, and usually lasts from June to September. Up to 90% of annual precipitation is received in some regions during the season. Note the dramatic difference in soil moisture between India and the Middle East.


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.
