GCIP LSA-E EAOP 1999 KELLOGG Surface Dataset 1.0 General Description The W.K. Kellogg Biological Station (KELLOGG) hourly dataset provided in the GEWEX Continental-Scale International Project (GCIP) Large-Scale Area North West (LSA-NW) Enhanced Annual Observing Period (EAOP) 1999 contains hourly surface meteorological and sub-surface soil temperature data from one site within the GCIP LSA-E EAOP 1999 domain (76W to 89W longitude and 33N to 43N latitude) and time period (01 October 1999 through 30 September 1999). Hourly precipitation, wind speed, wind direction, and temperature are also included in the GCIP LSA-E EAOP 1999 hourly surface composite. This dataset is provided as-is. No quality control was performed by the University Corporation for Atmospheric Research/Joint Office for Science Support (UCAR/JOSS). 2.0 Detailed Data Description The W.K. Kellogg Biological Station (KELLOGG) hourly surface dataset has been provided as-is by UCAR/JOSS. The data file contains tab-delimited hourly values for the LTER station WTHR located at 42.40917N latitude and 85.37167W longitude at an elevation of 286.5 meters. These data are provided by W.K. Kellogg as dataset KBS002, and source table LTERws. For more information on this dataset, please contact Garrett Ponciroli Information Manager Michigan State University W.K.

These parameters are listed below. Data Information Data fields are tab-delimited. Each line consists of the following parameters shown below: Parameters Description Units --------------------- ------------------------ ----------------- Date ARRAY_ID Array identification number TABLE_RECID Sampling table identification PROGRAM_VERSION Version of datalogger program when sampled YEAR Year in 4 digit format YYYY DAY_OF_YEAR Day of the year(1-366) Julian Day HOUR 24 hr time always set to HHMM Eastern Standard Time BATTERY_VOLTS Volts of power supply LC_RATIO Load Cell Ratio SD_LC_RATIO Standard Deviation of LC Ratio MASS_CHANGE LYS_1_DRAINAGE Drainage from Lysimeter 1 Millimeters LYS_2_DRAINAGE Drainage from Lysimeter 2 Millimeters RAIN Precipitation Millimeters PAR Photosynthetic radiation uE/m2/day SOLAR_RADIATION Total solar radiation cal/cm2/day WIND_SPEED Wind Speed Meters/Second WIND_DIRECTION N=0,Mean wind direction Degrees SD_WIND_DIRECTION Standard Deviation of wind direction WIND_SPEED_2 Mean Wind Speed Meters/Second RESULTANT_WIND_SPEED_2 Mean Wind Speed Meters/Second WIND_DIRECTION_2 Wind Direction Degrees SD_WIND_DIRECTION_2 Standard Deviation of wind direction WIND_SPEED_3 Mean Wind Speed Meters/Second WIND_DIRECTION_3 Wind Direction Degrees SD_WIND_DIRECTION_3 Standard Deviation of wind direction AIR_TEMP_HMP Air temperature from HMP RH Relative Humidity Percent SAT_VAPOR_PRESSURE Saturated vapor pressure AIR_TEMP_107 Air Temperature from 107 sensor Degrees Celsius SOIL_TEMP_1cm_ALFALFA Soil temperature at 1cm Degrees Celsius below surface beneath Alfalfa SOIL_TEMP_4cm_ALFALFA Soil temperature at 4.5cm Degrees Celsius below surface beneath Alfalfa SOIL_TEMP_11cm_ALFALFA Soil temperature at 11cm Degrees Celsius below surface beneath Alfalfa SOIL_TEMP_1cm_BARE Soil temperature at 1cm Degrees Celsius below surface beneath bare soil SOIL_TEMP_4cm_BARE Soil temperature at 4.5cm Degrees Celsius below surface beneath bare soil SOIL_TEMP_11cm_BARE Soil temperature at 11cm Degrees Celsius below surface beneath bare soil TDR_PERIOD_BARE CS615 Volumetric moisture period measurement TDR_PERIOD_ALFALFA CS615 Volumetric moisture period measurement VOL MOISTURE BARE TDR sensor volumetric moisture bare soil 30cm vertical VOL MOISTURE ALFALFA TDR sensor volumetric moisture alfalfa 30cm vertical BAROMETRIC_PRESSURE 2.2 Data Remarks The volumetric soil moisture needs to be calculated from the period using (0.2139*[TDR_PERIOD_BARE])-0.0623 for the bare soil sensor and (0.4139*[TDR_PERIOD_Alfalfa])-0.376 for the alfalfa cover sensor. The equation suggested by campbell, which the datalogger uses to calculate volumetric moisture from the TDR period, does not work for our location. The barometric pressure field and the lysimeter fields are left over from past experiments. They either do not function or do not exist. The following table lists all instruments located at the LTER site.
