林芝地区观测数据集（2010年4-5月）

本数据集为2010年藏东南林芝地区雅鲁藏布江河谷观测的数据集。观测地点为北纬29度26.898分，东经94度41.443分，观测时间为2010年6.1-6.30日。该数据集包括地面资料，大气湍流资料，大气辐射和土壤热通量资料，GPS探空资料.地面资料变量为近地面大气风向风速、气温、气压、相对湿度。大气湍流资料变量为采集频率为10Hz的CO2浓度，水汽密度，三维风速，大气虚温，气压值。大气辐射和土壤热通量资料变量为太阳向下辐射、地面反射短波辐射、大气向下长波辐射、地面向上长波辐射、净辐射和土壤温度、土壤湿度，数据时间分辨率为30min。GPS探空每日08bjt和20bjt释放两次，变量为不同高度的风向风速、气温、气压和相对湿度。

This dataset is the observational dataset collected in the Yarlung Zangbo River Valley, Nyingchi area, southeastern Tibet in 2010. The observation site is located at 29°26.898' N and 94°41.443' E, and the observation period is from June 1 to June 30, 2010. This dataset includes four categories of data: surface meteorological data, atmospheric turbulence data, atmospheric radiation and soil heat flux data, and GPS sounding data. The variables in the surface meteorological data cover near-surface wind direction and speed, air temperature, atmospheric pressure, and relative humidity. The variables in the atmospheric turbulence data, collected at a sampling frequency of 10 Hz, include CO2 concentration, water vapor density, three-dimensional wind speed, atmospheric virtual temperature, and atmospheric pressure. The variables in the atmospheric radiation and soil heat flux data include downward solar radiation, surface-reflected shortwave radiation, downward atmospheric longwave radiation, surface-upward longwave radiation, net radiation, soil temperature, and soil moisture, with a temporal resolution of 30 minutes. GPS sounding observations are launched twice daily at 08:00 BJT and 20:00 BJT, with variables including wind direction and speed, air temperature, atmospheric pressure, and relative humidity at different altitudes.
