基于卫星和常规气象观测数据的青藏高原大气热源/汇数据集（1984-2015）

青藏高原(TP)在春季和夏季作为一个巨大的高架式地表和大气热源，对区域和全球气候和气候具有重要影响。为了探讨TP的热强迫效应的多尺度时间变化，制备了青藏高原大气热源/汇数据集，作为计算气柱热收支的定量分析工具。
大气热源/汇数据集包含三个变量:地表感热通量SH、潜热释放LH和净辐射通量NR。
基于中国气象局(CMA)1979-2016年80(32)气象站6-h的常规观测数据：1.5m气温、10m地面温度和风速计算地表热通量数据，降水估算潜热释放量。用于计算净辐射通量的卫星数据集为全球能源和水循环实验地表辐射预算卫星辐射(GEWEX/SRB）和云和地球的辐射能系统(CERES/EBAF），利用GEWEX/SRB和CERES/EBAF大气表面和顶部(TOA)的短波和长波月辐射通量(short - twave and longwave radiation fluxes, TOA)，通过统计方法得到1984-2015年期间的净辐射通量。

The Tibetan Plateau (TP) acts as a massive elevated surface and atmospheric heat source in spring and summer, exerting significant impacts on regional and global climate. To investigate the multi-scale temporal variations of the thermal forcing effects over the TP, a Tibetan Plateau atmospheric heat source/sink dataset was developed as a quantitative analytical tool for calculating the column heat budget.
This dataset includes three variables: surface sensible heat flux (SH), latent heat release (LH), and net radiation flux (NR).
Based on 6-hourly routine observational data from 80 (32) meteorological stations of the China Meteorological Administration (CMA) during 1979-2016, including 1.5 m air temperature, 10 m surface temperature and wind speed, surface heat flux data were calculated, and latent heat release was estimated using precipitation data. The satellite datasets used to calculate net radiation flux are the Global Energy and Water Cycle Experiment Surface Radiation Budget (GEWEX/SRB) and Clouds and the Earth's Radiant Energy System (CERES/EBAF). Monthly shortwave and longwave radiation fluxes at the surface and top of atmosphere (TOA) from GEWEX/SRB and CERES/EBAF were utilized to derive net radiation fluxes during 1984-2015 via statistical methods.
