Greetings from Alfred State College in Alfred, New York! We are very excited to be participating in the NASA SMAP soil moisture sampling project. The project here is overseen by Jessica Hutchison, Instructor in the Department of Agriculture and Veterinary Technology. Two Agriculture Technology students, Kayana Fonseca and Peter Meyer, take samples and input data. We have one site, located right outside the greenhouse next to the agriculture building so we don't have to travel far to get a sample in bad weather. We are lucky to have a soils laboratory and sampling equipment right in the...

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 when it does it plays a large role in cloud formation. Soil moisture also has a modulating effect on air temperature and humidity therefore having the ability to measure soil moisture continuously...

December 1 to December 31, 2015 The GLOBE Program will host the annual surface temperature field campaign from December 1 to December 31, 2015.  This is a great opportunity to work as a community with schools around the world on a common research project. Students have used the surface temperature field campaign data to do research projects from fourth grade up to graduate students at universities. One of my graduate students published her masters thesis and found that a strong warming due to urban areas is observable in the student data. It is my hope that continued expansion of the...

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 resolution, one with high accuracy. THE INSTRUMENTS: Active (High Resolution): SMAP’s radar was designed accurately measure the echoes of very short radio frequency (RF) pulses that bounce (“backscatter”)...

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 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...
