Statement of Work (SOW) for

Project: Soil Climate Analysis Network (SCAN) Maintenance

GENERAL INFORMATION

1.0 Scope: The United States Department of Agriculture (USDA) National Resources

Conservation Service (NRCS) National Water and Climate Center (NWCC) operates and maintains the Soil Climate Analysis Network (SCAN) stations across the US, including Alaska, Hawaii, Puerto Rico and the US Virgin Islands, with a focus on U.S. agricultural areas. Currently, there are 210 SCAN stations that provide soil and climatic data in near real-time that are used for agricultural practices and climate analysis. In addition to the SCAN stations, the agency is currently involved with assisting tribes in the installation of Tribal SCAN (TSCAN) stations on lands across the US, focused on agricultural lands situated on Tribal lands in the U.S.

SCAN is an essential tool for assessing climatic conditions, carrying out precision agriculture and drought mitigation. The Under Secretary for USDA held a workshop in January 2020 to bring together other federal agencies in supporting SCAN as a tool with multiple applications that fits in with mission priorities. The network has generated widespread interest across government agencies and the data provide a unique representation of local, regional and national soil characterizations and hydrology. To accurately assess conditions, a long-term record is required for each site that spans decades, and therefore it is critical to properly maintain the current network while expanding the number of stations in areas with sparse data coverage.

2.0 Background: SCAN data collection station sites collect hourly information on soil moisture content and soil temperature at standard depths (2, 4, 8, 20, and 40 inches), air temperature, relative humidity, solar radiation, wind speed/ direction and liquid precipitation. Each station consists of a tower (typically 20 ft high), electronics box and soil probes. The sites utilize sensors for data collection and use primarily Cellular Telemetry, but in some cases, satellite transmitters are used. Sites are powered by 12-volt batteries that are charged by solar panels. Each site requires annual maintenance which includes changing out certain site components, maintaining site vegetation and making minor repairs. There are some sites that may require significant repairs that will require specialized experience and expertise related to electronics and the physical ability to climb towers and handle heavy and awkward loads (e.g., batteries, antennas, and solar panels).

SCAN is the largest comprehensive soil moisture monitoring network in existence and the only broad-scale network established with the purpose of collecting soil climate (temperature and moisture) data. There are many requests for new SCAN stations all the time from federal partners and the NRCS States across the US. In addition, there are guidelines set down by the Chief of NRCS as outlined in

National Instruction 450-303-NI, 1st Ed., Amend. 1, Mar 2018) 303-1 – Guidance on Soil Climate Analysis Network (SCAN) Station Investment related to external requests for new SCAN stations.
