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.
