7. DATASET OVERVIEW
7.1 AbstractObjectives
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. Atmospheric pressure isaveraged over the previous 30 minutes. Wind speed and direction are the resulting average speed anddirection over the previous 30 minutes (calculated by the data logger by means of data recorded every
5 seconds): this to minimize data unreliability due to sudden gusts. Snow depth is instantaneous
values of each 2 hours. The snow sensor is based on a 50 kHz (Ultrasonic) electrostatic transducer.
The SR50 determines the distance to a target by sending out ultrasonic pulses and listening forthe returning echoes that are reflected from the target. Air temperature is used to compensate thesnow data which is measured by using snow depth sensor. A temperature compensated distance fromSR50 to snow surface is obtained by multiplying the SR50 reading by the square root of the airtemperature in degree Kelvin divided by 273.15.
DISTANCE = READINGSR50×root( T (K) / 273.15(K) )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”, In
the case of calculated by using dubious value fagged “D”, the data flag was put “D”.

Dew Point Temperature 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));4

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 were computed by using (Bolton 1980):
e = 6.112*exp((17.67*Td)/(Td + 243.5));q = (0.622 * e)/(p - (0.378 * e));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 were computed by using (GEMPAK):
U = -sin(direction) * wind_speed;
V = -cos(direction) * wind_speed;
Net radiation were computed by using (GEMPAK):
NET_radiation = down(in)short + down(in)long - up(out)short - up(out)long;
