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...

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...

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...

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...

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...

Guest Blog by NASA SMAP Scientists Dr. Erika Podest and Dr. Narendra Das of the NASA Jet Propulsion Laboratory in Pasadena, California USA. SMAP scientists are using soil moisture in a number of ways, ways that allow all of us to better understand water’s role on Earth: Weather Prediction: Water in the soil has the potential to evaporate (depending on atmospheric temperature and pressure) and...

Have you ever wondered how the SMAP satellite, with an altitude of 685 km (425 miles) above the Earth, can take measurements as precise as the amount of water in the Earth's soil? The quick answer is that it requires precisely calibrated instruments, along with a technological marvel in satellite design. SMAP was designed to use a combination of two precise instruments, one with high...

The SMAP Mission is vital to understanding our planet. Water is an essential source for life. By understanding the amount of water in the soil, or soil moisture, we can apply this information to many things. Monitoring Drought 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...

Weekly Report 1: 10/1/15 - 10/15/15 This report contains two weeks of data collection due to the beginning of the campaign on October 1, 2015: Volumetric Soil Moisture Measurements = 19 Participating Sites = 4 Schools Submitting Data: Shumate Middle School - Michigan - 8 data counts Ramey School - Puerto Rico -7 data counts The University of Toledo -Ohio - 2 data counts Thomas Edison...
