A high-resolution dataset for lower atmospheric process studies over the Tibetan Plateau from 1981 to 2020

Meteorological elements of the dataset include the near-surface land-air exchange parameters, such as downward/upward longwave/shortwave radiation flux, momentum flux, sensible heat flux, latent heat flux, etc. In addition, the vertical distributions of 3-dimensional wind, temperature, humidity, and pressure from the surface to the tropopause are also included. Independent evaluations were conducted for the dataset by comparison between the observational data and the most recent ERA5 reanalysis data. The results demonstrate the accuracy and superiority of this dataset against reanalysis data, which provides great potential for future climate change research.

本数据集包含近地表陆地-大气交换参数的气象要素，诸如向下/向上长波/短波辐射通量、动量通量、感热通量、潜热通量等。此外，还包括从地表至对流层顶的3维风速、气温、湿度和气压的垂直分布情况。通过对观测数据与最新版本的ERA5再分析数据进行对比，对该数据集进行了独立评估。结果显示，该数据集在准确性及优越性方面均优于再分析数据，为未来气候变化研究提供了巨大的潜力。
