High resolution satellite and reanalysis-based air temperature estimates have huge potential to complement the sparse networks of measurements from ground stations in Africa. The recently released Climate Hazards Center Infrared Temperature with Stations (CHIRTS-daily) dataset provides daily minimum maximum on a near-global scale 1983 2016. This study assesses performance CHIRTS-daily compariso...

Based on the in situ data of soil moisture-observation networks established at Maqu, Naqu, Ali, and Shiquanhe (Sq) Tibetan Plateau (TP), using five evaluation indices [Pearson correlation coefficient (R), root mean square error (RMSE), deviation (bias), standard ratio (SDV), unbiased RMSE (ubRMSE)], applicability moisture datasets [COMBINED, ACTIVE, PASSIVE, ERA5, ERA5-Land (LAND), ERA-Interim ...

Serving as the successor to ERA-Interim dataset, a new global reanalysis (i.e., ERA5) has been released by European Centre for Medium-Range Weather Forecasts. However, evaluation of performance ERA5 in relation Tibetan Plateau (TP) remains lacking. Using situ eddy covariance observations from eight stations located on TP, this study evaluated uncertainties both and ERA-Interim. Results showed t...

Three-dimensional water vapor can be reconstructed from Global Navigation Satellite System (GNSS) observations, which can study 3-D profile variations of atmospheric water vapor and climate. However, there is a large uncertainty of water vapor tomography from single GPS system observations due to limited satellites. The rapid development of multi-GNSS, including China’s Beidou Navigation Satell...
