NASA’s Soil Moisture Active Passive (SMAP) satellite mission, scheduled to launch this winter, will collect the kind of local data agricultural & water managers worldwide need. SMAP uses 2 microwave instruments to monitor the top 2 inches of soil on Earth’s surface. Together, the instruments create soil moisture estimates with a resolution of about 6 miles, mapping the entire globe every 2 or 3 days.
