Did you know that soil moisture plays a vital role in human health? Those nasty little critters called mosquitoes love warm, wet soil, and can carry extremely dangerous viruses and diseases. We also can use SMAP soil moisture data to assist famine early warning systems. Improved seasonal soil moisture forecasts using SMAP data will directly benefit famine early warning systems particularly in sub-Saharan Africa and South Asia, where hunger remains a major human health factor and the population harvests its food from rain-fed agriculture in highly monsoonal (seasonal) conditions. In...

The NASA SMAP satellite took off for space on January 31, 2015 to study our planet's soil moisture and freeze/thaw state. Once in space, the satellite had to go through a prescribed series of steps to ensure that the spacecraft was functioning and all its instruments and components on-board were working properly. This took several months. In mid-April 2015, NASA starting receiving its first soil moisture measurements from SMAP's combined high resolution radar and its high accuracy radiometer. The combination of this data produced a data resolution of approximately 8km. Unfortunately,...

There are many application for SMAP soil moisture satellite data. Understanding drought risk is vital to the health of the planet and to the lives of potentially billions of people around the world. Soil moisture strongly affects plant growth and hence agricultural productivity, especially during conditions of water shortage and drought. Currently, there is no global in situ network for soil moisture monitoring. Global estimates of soil moisture and plant water stress must be derived from models. These model predictions (and hence drought monitoring) can be greatly enhanced through...

We all know that the SMAP satellite measures soil moisture. But, how does knowing our planet's soil moisture help us in understanding agriculture's reaction to it? SMAP monitors soil moisture and provides critical information for drought early warning. In fact, a deficit in the amount of moisture in the soil defines agricultural drought. SMAP's measurements will come into play because researchers forecast a threefold increase in drought frequency in many regions of the world by the end of the 21st Century. History shows that a sustained drought can result in crop failure, deaths of...

Hello from Medford Memorial Middle School in Medford, New Jersey. The quest to get an accurate soil sample continues at Medford Memorial Middle School, Medford NJ. Hello, we are the students of Memorial’s Citizen Science Education Program. We’re excited to be part of the SMAP campaign, but have not yet been able to enter any data.  Here’s a brief overview of our journey. First, we learned about SMAP as a satellite, and then we studied the protocol. We didn’t have any soil sample cans, so we settled on a sturdy coffee can, Ryan had brought in from home. Ashwin measured 5 cm from the...
