1-degree annual mean 2-meter air temperature (used in the model
    as bottom boundary layer conditions for soil models)


       a) data file: SOILTEMP.60  (Unit: Kelvin)
       b) resolution: 1 degree
       c) program: read_soil_t.f
          To save the disk space, all input data are in character
          strings (either 1-character string (for land-use, land-water, vegetation
          fraction) or two-character string (for soil temperature)). The program
          provided here is used to transfer these characters into integer.
       d) Note: The boundary soil temperature data starts at
          latitude 89.5 and longitude -179.5. The file is in direct access
          format. Each direct access record contains data in one latitude
          circle beginning at -179.5 degree longitude and ending
          at +179.5 degree. The data are arranged to start at northernmost
          latitude (north pole) and end at south pole. 
       e) Note: This date set is based on 1-degree 2-meter air temperature 
          from the ISLSCP-I dataset. It is two-year monthly 6-hourly
          2-meter air temperature from the ECMWF model analysis and 
          depends on the ECMWF model orography. Hence, this temperature is 
          first adjusted to the 1000 mb level using the ECMWF
          annual analyzed surface pressure (also available from the
          ISLSCP dataset) according to the standard atmosphere lapse rate.
