Abstract: U.S. Soil Temperatures is historical digital data set DSI-9639, archived at the National Climatic Data Center (NCDC). The major parameters that make up this soil-temperature DSI-9639 data file are depth of soil temperature measurements (inches or centimeters), soil type (coded), and daily temperatures (deg f). The primary source of this file is from daily measurements taken by the federal ... government, state government and university sponsored agriculture research and experiment stations that are part of the cooperative station network. Each soil record contains the daily soil temperature measurement for a particular depth. The record includes the time of the observation, the depth of the soil reading, soil type, plus the monthly extremes (maximum, minimum) and the average monthly soil temperature. Depth maybe recorded in inches or centimeters. The soil types are grass, fallow, bare ground, brome grass, sod, straw mulch, or muck. The digital data are for the period from January 1967 through December 1981. Soil data after 1981 are produced and stored on DSI-3200 Cooperative Summary of the Day (C00314).
