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. 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...

GOES Evapotranspiration and Drought (GET-D) products are derived from the Atmosphere-Land Exchange Inversion model (ALEXI). ALEXI computes principle surface energy fluxes, including Evapotranspiration (ET), which is a critical boundary condition to weather and hydrologic modeling, and a quantity required for regional water resource management. ALEXI ET estimates have been rigorously evaluated in comparison with ground-based data, and perform well over a range in climatic and vegetation...
The Keetch-Byram Drought Index assesses the risk of fire by representing the net effect of evapotranspiration and precipitation in producing cumulative moisture deficiency in deep duff and upper soil layers. The index ranges from zero, the point of no moisture deficiency, to 800, the maximum drought that is possible.
National Weather Service (NWS) Climate Prediction Center (CPC) generates Regional Climate Maps for the United States. These maps are available in weekly, one-, three-, and twelve-month maps depicting total percipitation, precent of normal precipitation, average temperature, maximum and minimum temperatures, and departures from normal.
The National Operational Hydrologic Remote Sensing Center (NOHRSC) provides remotely-sensed and modeled hydrology products for the coterminous U.S. and Alaska for the protection of life and property and the enhancement of the national economy....
Climate outlooks describe the chances that conditions will be below-normal, near-normal, or above-normal for the outlook period indicated. The U.S. Monthly Drought Outlook is issued at the end of each calendar month and is vaild for the upcoming month. The Outlooks predicts whether drought will emerge, stay the same or get better over the next 30 days or so.
Where do these data come from?
Climate scientists base future climate outlooks on current patterns in...
The Regional Climate Centers (RCC) Applied Climate Information System (ACIS) offers interactive charts with single- or multi-station capabilities. Station products include daily or monthly precipitation, temperature, snow depth, snowfall, heating degree days and cooling degree days observations.
How scientists use “climate proxies” to reconstruct past events
Weather data from stations around the globe are used to calculate the current Standardized Precipitation Index (SPI) for each station.
