青藏高原高分辨率低层大气和地气交换长期数据集（1981-2020）

青藏高原分区域动力降尺度（TPSDD）数据集是一个高空间-时间分辨率的网格数据集，用于整个青藏高原的陆地-空气交换过程和低层大气结构研究，并考虑到了青藏高原各分区域的气候特征。该数据集的时间跨度为1981年至2020年，时间分辨率为2小时，空间分辨率为10公里。数据集的气象要素包括近地表土地-空气交换参数，如向下/向上的长波/短波辐射通量、动量通量、显热通量、潜热通量等。此外，还包括从地表到对流层顶的3维风、温度、湿度和气压的垂直分布。通过比较观测数据和最新的ERA5再分析数据，对该数据集进行了独立评估。结果表明了该数据集的准确性和优越性，为未来的气候变化研究提供了巨大的潜力。

The Tibetan Plateau Sub-regional Dynamical Downscaling (TPSDD) dataset is a high spatiotemporal resolution gridded dataset developed for studies of land-atmosphere exchange processes and lower atmospheric structure across the entire Qinghai-Tibet Plateau, while accounting for the climatic characteristics of each sub-region on the plateau. This dataset spans the period from 1981 to 2020, with a temporal resolution of 2 hours and a spatial resolution of 10 km. Its meteorological variables include near-surface land-atmosphere exchange parameters, such as downward/upward longwave and shortwave radiative fluxes, momentum flux, sensible heat flux, latent heat flux, and others. Additionally, it covers the vertical distributions of 3-dimensional winds, temperature, humidity and atmospheric pressure from the surface up to the tropopause. This dataset was independently evaluated through comparisons with in-situ observational data and the latest ERA5 reanalysis dataset. The results demonstrate the accuracy and superiority of this dataset, which holds great potential for future climate change research.
