This data set contains hourly soil temperature (2cm, 5cm, 10cm, 20cm, 50cm, and 100cm depth) and soil heat flux (0cm depth) data from three stations 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 MAGS BERMS Algorithms 3.1.1 Native format data The BERMS (Boreal Ecosystem Research and Monitoring Sites) project was designed as a 5 year partial follow-up to the BOREAS (Boreal Ecosystem- Atmosphere Study) experiment. The data set documented here includes the near- surface meteorological measurements of three forest biomes in the southern boreal forest of Saskatchewan (referred to as the Southern Study Area in BOREAS). Prior to BERMS, the Saskatchewan Research Council maintained near- surface meteorological stations throughout the BOREAS study area from December, 1993 until December, 1996. After this, the Climate Research Branch in Saskatoon took over the climate monitoring program at two of these stations, Old Aspen and Old Jack Pine. The BERMS climate monitoring program differed somewhat from SRC's program in that the instrumentation was installed on different platforms and the number of variables measured was expanded. In addition to the expanded climate monitoring at Old Aspen and Old Jack Pine, there was also a climate station installed at Old Black Spruce to measure the same variables as at the other two stations. 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". For a document describing the native format data, including extensive notes on the instrumentation used and data collection algorithms, see the Data Documentation bullet at http://berms.ccrp.ec.gc.ca/data/dataindex.htm. 3.1.1 CEOP/EOP-1 Hourly Soil Heat Flux, Moisture, and Temperature format data This CEOP/EOP-1 MAGS BERMS 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. In the native format, soil temperatures were provided at a depth of 2cm, 5cm, 10cm, 20cm, 50cm, and 100cm. The soil heat flux provided in the native format was at a depth of 0cm. No soil moisture was provided in the native format data. All soil temperature and soil heat flux provided in the native format data is included in this data set. 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 MAGS BERMS data set. The actual station information is given at the end of this section. Table 1 details the station list parameters. 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. Table 4 contains the station information for this CEOP MAGS BERMS data set.

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 5 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.
