CRN FTP SOILSIP01 STREAM
------------------------

NCDC provides ftp access to soil moisture/soil temperature data from the Climate 
Reference Network (CRN) via anonymous ftp at the address

        ftp://ftp.ncdc.noaa.gov/pub/data/uscrn/products/soilsip01

That directory contains this README.txt file and a fixed-width ASCII file for each station, named
according to the following convention:

        CRNSIP01_{name}.txt

        where
          {name} = Unique station name (state location vector) with spaces replaced by underscores (e.g. AZ_Tucson_11_W)

Each file contains a line for each hour in the station's SM/ST period of record.  Each of these lines contains
values, in a fixed-column format, for the variables listed below:

cols   1 - 10: UTC_DATETIME: the UTC date and time of the end of the hour of observation, in the format YYYYMMDDHH
        
      12 - 16: WBANNO: the station's WBAN identification number
        
      18 - 23: COOPNO: the station's COOP identification number
        
      25 - 31: LATITUDE: WGS-84
      33 - 39: LONGITUDE: WGS-84

      41 - 47: SOIL_MOISTURE_5
      49 - 55: SOIL_MOISTURE_10
      57 - 63: SOIL_MOISTURE_20
      65 - 71: SOIL_MOISTURE_50
      73 - 79: SOIL_MOISTURE_100: five variables representing the average volumetric water content 
                                  as a percentage at each of five depths.
         	
      81 -  87: SOIL_TEMP_5
      89 -  95: SOIL_TEMP_10
      97 - 103: SOIL_TEMP_20
     105 - 111: SOIL_TEMP_50
     113 - 119: SOIL_TEMP_100: five variables representing the average temperature in Celsius 
                               at each of five depths.


NOTES:

        Missing data are indicated by the value -9999.0. Values are missing when the CRN QC process determines that
        the raw data are not of sufficient quality to determine an average value for volumetric water content or for
        soil temperature.
