This data set contains hourly soil heat flux values at 2cm and 5cm depths 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 3.1 LBA Pantanal Algorithms The algorithms used to produce the LBA Pantanal native format data are not currently available. The automatic weather station and eddy correlation system are installed on IPE site. 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". This CEOP/EOP-1 LBA Pantanal 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. Soil Heat Flux values are provided at 2cm and 5cm depths. No soil moisture or soil temperature values were provided in the native format data. 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 LBA Pantanal data set. Table 1 details the station list parameters. LBA Pantanal 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.
