7. DATASET OVERVIEW
7.1 Abstract
Objectives
The goal of the GAME-Siberia project is to clarify the characteristics and processes of water
accumulation and transfer and their relation with the energy cycle, in the atmosphere-land surface
interface of cold environments from the seasonal to the inter-annual time scale. This study willcontribute to one of the primary GAME objectives;
�To understand multi-scale interactions in the energy and hydrologic cycles in the Asian Monsoon
Regionand one scientific objective;�To assess the impact of monsoon variability on the regional hydrologic cycle.
The objectives of Taiga study subgroup include:
1.Develop seasonal and inter-annual variation of one-dimensional energy and water vapor fluxes
over tundra.

2

2.Characterize the water balance components in these Taiga watersheds.
3.Determine the areal distribution of ground surface properties.

8. DATA PROCESSING
8.1 Data Processing (1)8.1.1 General Explanation of the data producer's knowledge about thelineage of a dataset
Temperature, relative humidity and radiation are instantaneous values. Precipitation is accumulatedon the previous hour. Atmospheric pressure is averaged over the previous hour. Wind speed anddirection are the resulting average speed and direction over the previous hour (calculated by thedatalogger by means of data recorded every 5 seconds): this to minimize data unreliability due tosudden gusts. Both of them are calculated weighting the frequency distribution of both variables
within each hour. Snow depth is averaged over the previous hour.
And the four parameters indicated below were computed by using “CEOP Derived Parameter Equations :http://www.joss.ucar.edu/ghp/ceopdm/refdata_report/eqns.html” . also put the data flag “I”,
Dew Point Temperature (10m) were computed by using (Bolton 1980):
es = 6.112 * exp((17.67 * T)/(T + 243.5));e = es * (RH/100.0);
Td = log(e/6.112)*243.5/(17.67-log(e/6.112));
where:
T = temperature in deg C;
es = saturation vapor pressure in mb;
e = vapor pressure in mb;
RH = Relative Humidity in percent;
Td = dew point in deg C
Specific Humidity (10m) were computed by using (Bolton 1980):
e = 6.112*exp((17.67*Td)/(Td + 243.5));q = (0.622 * e)/(p - (0.378 * e));4where:e = vapor pressure in mb;
Td = dew point in deg C;
p = surface pressure in mb;
q = specific humidity in kg/kg.
U,V Components (10m) were computed by using (GEMPAK):
U = -sin(direction) * wind_speed;
V = -cos(direction) * wind_speed;
Outgoing Short wave radiation(1.5m) were computed by using (GEMPAK):
Up(Out)short radiation = down(in)short + down(in)long - up(out)long - NET_radiation;

9. DATA REMARKS
For all parameters, the data has been visually checked, looking for extremely and unusual low/highvalues and/or periods with constant values thorough the CAMP Quality Control Web Interface.
The quality control flags follow the CEOP data flag definition document.
"D" is put as a questionable or dubious flag for the Longwave downword Radiation, the Shortwave
downward Radiation, and the Net Radiation data.
We assume that these Radiation data were caused by snow or frost coverage on the sensor in winterseason.
UCAR/JOSS conducted two primary quality assurance/control procedures on the reference site data.
First the data has been evaluated by a detailed QA algorithm thatVerifies the format is correct, examines any QC flags, and conducts basic checks on datavalues. Second, JOSS conducts a manual inspection of time series plots of each parameter.
