2.0 General Description
This data set contains the Coordinated Enhanced Observing Period (CEOP)
Enhanced Observing Period 1 (EOP-1) CEOP Asian-Australia Monsoon Experiment
(CAMP) Northern South China Sea - Southern Japan Hourly Soil Heat Flux,
Moisture, and Temperature Data Set. This data set contains hourly soil
temperature (5cm, 10cm, 20cm, and 30cm depth) data from 14 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.

3.1.1 Native format data

This data set is also available on-line in native format at
under the heading CEOP EOP-1 "Native Format" Reference Site Data Sets,
CAMP. For a document describing the native format data, see the
Documentation provided at the same site.

3.1.1 CEOP/EOP-1 Hourly Soil Heat Flux, Moisture, and Temperature format data

This CEOP/EOP-1 CAMP Northern South China Sea - Southern Japan Hourly Soil
Heat Flux, Moisture, and Temperature data set was formed by reformatting the
thrice daily observations from the native format data. 

In the native format, only soil temperatures were provided at a depth of 5cm,
10cm, 20cm, and 30cm. No soil moisture, or soil heat flux data were provided.
All soil temperatures provided in the native format data are 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. 

3.2 Station Information

The following is a complete description of the station information provided 
with this CEOP CAMP Northern South China Sea - Southern Japan data set. The
actual station information is delivered with the data. 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 CAMP Northern South China Sea -
Southern Japan data set.

3.3  Detailed Format Description
The CEOP EOP-1 CAMP Northern South China Sea - Southern Japan Hourly Soils
Data Set contains 11 metadata parameters followed by parameter values for 26
soils depths (i.e., 0,2,3,4,5,6,7,8,10,15,16,20,25,30,32,35,40,45,50,
60,64,85,100,125,150,175 cm). 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.
