Soil Climate Analysis Network

The Soil Climate Analysis Network, also known as SCAN, supports natural resource assessments and conservation activities through its comprehensive, nationwide soil moisture and climate information network.

The Soil Climate Analysis Network (SCAN) began as a soil moisture/soil temperature pilot project of the Natural Resources Conservation Service in 1991. The system is designed to provide data to support natural resource assessments and conservation activities. More recently, the Tribal Soil Climate Analysis Network (Tribal SCAN) was developed to support similar activities on Tribal lands across the U.S.

The SCAN system focuses on agricultural areas of the U.S. and is composed of over 200 stations. A typical SCAN site monitors soil moisture content at several depths, air temperature, relative humidity, solar radiation, wind speed and direction, liquid precipitation, and barometric pressure. 

Soil Data, Products, and Resources

Tribal SCAN

National Water and Climate Center

The National Water and Climate Center administers the Snow Survey and Water Supply Forecasting Program and the Soil Climate Analysis Network, and manages the Water and Climate Information System.

Decision Tools for the Soil Climate Analysis Network

This site provides decision tools and resources using data from weather stations in the SCAN and Tribal SCAN Networks. This project is a collaboration between the following partners USDA, NRCS, ACIS, and Cornell University.

National Soil Moisture Network

This site supports operational monitoring of soil moisture conditions in the contiguous United States. It utilizes in situ measurements of soil moisture as well as model-derived and satellite-derived soil moisture to develop high-resolution (4 km) gridded soil moisture products for the contiguous Un
