The dataset of “The 2nd Comprehensive Scientific Expedition to the Qinghai Tibet Plateau” by the College of Atmospheric Sciences was released

May 28, 2024

【 News 】Recently, the National Tibetan Plateau Data Center (TPDC) released and shared “High resolution assimilation dataset of land atmosphere interaction on the Qinghai Tibet Plateau (2000-2022)”. The dataset was developed by Professor Wen Xiaohang and Professor Li Maoshan from the School of Atmospheric Sciences of our university in collaboration with the School of Atmospheric Sciences of Sun Yat-sen University and the Climate Center of Sichuan Province.

The Qinghai Tibetan Plateau is an important part of the global climate system, which influences regional and global climate through complex thermodynamic mechanisms. However, due to the steep terrain, harsh climatic conditions and sparse distribution of meteorological observation stations, it is difficult to accurately quantify the land-atmosphere coupling system over the Qinghai Tibet Plateau and its impact on surrounding areas. At present, there are some challenges in global meteorological reanalysis data, such as coarse spatial resolution (tens of kilometers) and low temporal resolution (3-6 hours interval), which limit its wider scientific application. In order to solve these problems, the research team of our university created the Qinghai Tibetan Plateau High Resolution Assimilation Dataset (QTP-HRAD) by using WRF model and 3D-var data assimilation method. The dataset covers the spatial range of 70 ~ 110°E and 25 ~ 40°N, with a spatial resolution of 5 km and a temporal resolution of 1 hour, and can be used for detailed studies of land atmosphere interaction, water cycle, radiation energy transport processes, and extreme weather and climate events over the Qinghai-Tibetan Plateau.

The results are supported by the Second Comprehensive Scientific Expedition to Qinghai-Tibet Plateau, “The Land Atmosphere Interaction on the Heterogeneous Underlying Surface of the Westerly Wind – Monsoon Section and the Influence on Weather and Climate (2019QZKK010304)”, and the relevant paper is published in the journal Remote Sensing.
