USDA NASS Launches New Soil Moisture Portal

On Monday, March 8th, the USDA National Agricultural Statistics Service (NASS) issued a new online portal to viewing soil moisture data from NASA. The new system, known as Crop Condition and Soil Moisture Analytics (Crop CASMA) provides high resolution data from NASA's Soil Moisture Active Passive (SMAP) mission and the Moderate Resolution Imaging Spectoradiometer (MODIS) instrument in a user friendly format. The tool was developed in partnership with NASA and George Mason University (GMU).

NASA Data Powers New USDA National Agricultural Statistics Service Soil Moisture Portal

WASHINGTON, March 8, 2021 – Farmers, researchers, meteorologists and others now have access to high-resolution NASA data on soil moisture, thanks to a new tool developed by USDA’s National Agricultural Statistics Service (NASS) in collaboration with NASA and George Mason University (GMU).

The tool, Crop Condition and Soil Moisture Analytics (Crop-CASMA), provides access to high-resolution data from NASA’s Soil Moisture Active Passive (SMAP) mission and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument in a user-friendly format. Soil moisture data are critical for professionals in the agriculture and natural resource sectors who use soil moisture in tandem with other data to plan crop planting, forecast yields, monitor droughts or floods, and improve weather forecasts. Crop-CASMA is available for free online at https://cloud.csiss.gmu.edu/Crop-CASMA/.

According to Rajat Bindlish, a research associate in Earth science remote sensing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, the tool provides more thorough spatial coverage and consistency than other soil moisture measurement methods.

“Soil moisture is a very important piece of information for agricultural yield and productivity,” said Bindlish. “This will provide a means of using NASA remote sensing data to guide predictions of moisture conditions and water availability. Information on the field conditions is important for agricultural operations.”

Some of Crop-CASMA’s primary users will be NASS researchers and statisticians who release weekly Crop Progress Reports that currently classify states into moisture categories (very short, short, adequate, surplus) to aid farmers and farm managers. The reports also track crops’ health and growing progress.

“USDA researchers and statisticians will incorporate the tool into a range of applications,” said NASS Spatial Analysis Research lead Rick Mueller. “For example, Crop-CASMA can help identify areas that could not be planted because of wet, saturated, frozen, excessively dry, or inaccessible fields resulting in improved planted statistical acreage estimates.”

Mueller noted that in addition to supporting agricultural operations, Crop-CASMA will enable research on sustainability and the impact of extreme weather events. “These satellite-derived vegetation condition indices and soil moisture condition maps show first-hand the ever-changing landscape of U.S. agriculture,” he said.

The tool is formatted to be accessible to private users, including farmers, researchers, and students, according to Crop-CASMA project leader Zhengwei Yang, a USDA geographer and co-investigator of the High-Resolution Soil Moisture Development Project.

“We created an easy-to-use interface that requires little technical background to use,” said Yang. “There’s a tool to select an area and create a map you can save as a PDF, and you can also download data from the web to input into your model.”

This work was supported by NASA Applied Sciences’ Earth Science Division's Western Water Applications Office (WWAO) and the NASA Terrestrial Hydrology Program. WWAO’s mission is to improve how water is managed in the arid western United States, and the tool is part of a portfolio of water projects that use the power of remote sensing to deliver new solutions on issues such as drought, snowpack, and water supplies.

“We know from our water partners in the western United States that there is a critical need for soil moisture data,” explained Indrani Graczyk, manager of WWAO. “This project was a great opportunity to partner with the USDA to get NASA data directly into the hands of farmers, and we were happy to support it.”

SMAP data, the foundation for Crop-CASMA, draw from the topsoil and rootzone levels, or from the surface to roughly 3 feet (1 meter) underground. Raw SMAP data have a 36-kilometer (roughly 20-mile) spatial resolution, meaning each data “footprint” is about the size of a county. The team also developed a data analysis method to estimate a higher-resolution soil moisture product using SMAP and land surface data, giving users information at 1-kilometer (0.62-mile) resolution.

Having the data in finer resolution allows users to more accurately pinpoint areas of high or low moisture, Yang explained. “Our current reports are at the state level,” Yang said. “One state may be categorized on average as ‘wet,’ but the whole state might not actually be wet. These new data deliver localized moisture readings – this is what matters to the farmer.”

Crop-CASMA was developed in cooperation with the Center for Spatial Information Science and Systems (CSISS) at GMU, NASA’s Goddard Space Flight Center, and NASA’s Jet Propulsion Laboratory (JPL). JPL manages the SMAP mission for NASA, and Goddard produces the SMAP 9-km rootzone and 1-km surface soil moisture products. Hosted and maintained by the CSISS, the online tool is operated by NASS’s Research and Development Division.

“We are very happy with the research collaboration between NASA’s Goddard Space Flight Center, NASA JPL, and GMU, and the project coordination of USDA’s Agricultural Research Service, and thank them for their support in bringing cutting-edge technology into USDA operations,” said Yang.

This collaboration is part of a larger, recently-signed agreement between USDA and NASA to jointly strengthen agricultural and Earth science research.

“Having the SMAP soil moisture data going directly to the users at NASS realizes one of the key goals of the mission,” said Simon Yueh, SMAP project scientist at JPL. “A strong collaboration between NASA and USDA has made this possible.”

There was a request for a more in depth presentation of how to use this tool. National Agriculture Statistics Service (NASS) Research Division is going to do a presentation for Delta Agriculture’s Industry Leaders. The presenters will be Zhengwei Yan and Arthur Rosales. Please feel free to forward this invite. Note that we do have a capacity of 350 guests. If you have any questions please give myself 501-322-9961 or Michael Klamm 501-322-2351 a call. Thank you all for your interest.

USDA National Agriculture Statistics Service Delta Region and Research Division is inviting you to a scheduled ZoomGov meeting.
