Introduction of a Field Experiment over the Complex Terrain in the Southeast Himalayas, Tibetan Plateau

In the spring and summer time of 2013, a comprehensive observational campaign "Observation on the Surface-to-air Exchange Processes in the Southeast Himalayas" (OSEP) were carried out in the southeast Himalayas, Tibetan Plateau, for better understanding the near-surface air exchange processes under complex terrains. During the OSEP2013 campaign, six observation sites were established near the Yarlung Zangbo River valley, together with the nearby two stations. The near-surface air mass/energy exchange parameters were measured, such as the global and net radiation fluxes, air temperature, soil temperature, moisture and wind were measured by weather stations (MAWS from Vaisala), and the turbulent transfer parameters by an ultrasonic anemometer (CSAT3 3-D from Campbell), with sonic virtual temperature and CO2/H2O measurements (LI7500 from Li-Cor), at 10 Hz sampling frequency, at 2 m above the ground. In addition, the vertical distributions of wind and temperature, moisture were also obtained by a Lidar wind-profiler a sonding system. The detail of this campaign will be introduced in the meeting, together with the preliminary analysis results.
