Box 2456 Oak Ridge, TN 37831-2456 USA Telephone: 423-576-1233 E-mail: firstname.lastname@example.org 2.0 General Description This data set contains the Coordinated Enhanced Observing Period (CEOP) Enhanced Observing Period 1 (EOP-1) Global Energy and Water Cycle Experiment (GEWEX) Americas Prediction Project (GAPP) Bondville Hourly Soil Heat Flux, Moisture, and Temperature Data Set. This data set contains hourly soil heat flux (0cm depth), soil temperature (2, 4, 8, 16, 32, and 64cm depths), and soil moisture (10, 30, and 60cm depths) data from a single station for the CEOP EOP-1 time period (01 July 2001 to 30 September 2001). The University Corporation for Atmospheric Research/Joint Office for Science Support (UCAR/JOSS) did not perform quality control processing on this data set. 3.0 Detailed Data Description This data set is also available on-line in 30-minute native format at http://www.joss.ucar.edu/ghp/ceopdm/ under the link "CEOP EOP-1 Reference Site Data Sets" 3.1 GAPP Bondville Algorithms The algorithms used to produce the GAPP Bondville native format data are not currently available. This CEOP/EOP-1 GAPP Bondville Hourly Soil Heat Flux, Moisture, and Temperature Data Set hourly data set was formed by extracting the top of the hour observations from the 30 minute native format data. The data were provided in local standard time and were converted to UTC time by adding 6 hours to the local standard time. The soil heat flux provided in the native format was assumed to be at a depth of 0 cm. More information regarding this site can be found under the CEOP Reference Site Station Characteristics link on the UCAR/JOSS CEOP Data Management page at http://www.joss.ucar.edu/ghp/ceopdm/. 3.2 Station Information The following is a complete description of the station information provided with this CEOP GAPP Bondville data set. Table 1 details the station list parameters. GAPP Bondville values for each parameter are listed in brackets at the end of each line. The beginning and ending dates for the period of coverage are in Universal Time Coordinated (UTC). The Identification Type field is network dependent and indicates the source of the Identification field. The Occurrence field is an integer value used to indicate co-located stations. Note that when a particular parameter is unknown for a station, either a blank, a question mark, or all 9's will appear in that parameter's position. For a complete list of Country, State, and County values, refer to the document in the references (Section 5.0). Possible platform types and frequency values are listed in Tables 2 and 3, respectively. Note that only those platform types present in the CEOP EOP-1 data have been listed.

The metadata parameters describe the station location and time at which the data were collected and the record type. The record type describes the type of data found on that record and is described in the Table 4 below. The time of observation is reported both in Universal Time Coordinated (UTC) Nominal and UTC actual time. Days begin at UTC 0100 and end at UTC 0000 the following day. Note that missing parameter values are indicated by "-999.99". The table below details the parameters in each record.
