This study evaluated the performance of 07 gridded datasets viz. Asian Precipitation Highly-resolved Observational Data Integration towards Evaluation of Water Resources (APHRODITE), Climate Research Unit Time-Series (CRU-TS), University of Delaware (UDEL), Tropical rainfall Measurement Mission (TRMM)/ TMPA (TRMM Multi-Satellite Precipitation Analysis), Global Precipitation Climatology Centre (GPCC), Princeton Global Forcings Dataset (PGF), and European Reanalysis Interim (ERA-I) in capturing the amount, seasonality and trend of precipitation over different climatic zones of Northwestern Himalaya (NWH) i.e. Lower Himalaya (LH), Greater Himalaya (GH) and Karakoram Himalaya (KH). A similar comparison was also done for the temperature data but only with 05 datasets, viz. APHRODITE, CRU-TS, PGF, UDEL and ERA-I since TMPA and GPCC are precipitation datasets only. This study is a maiden attempt where in situ observation includes the data from elevations above 5000 m amsl (07 ob...

喜马拉雅西北地区各种网格化温度和降水数据集的性能

这项研究评估了07个网格化数据集的性能。亚洲降水高度解析的观测数据集成，用于水资源评估（APHRODITE），气候研究单位时间序列（CRU-TS），特拉华大学（UDEL），热带降水测量任务（TRMM）/ TMPA（TRMM多卫星）降水分析），全球降水气候中心（GPCC），普林斯顿全球强迫数据集（PGF）和欧洲再分析中期（ERA-I），以捕获喜马拉雅西北（NWH）不同气候区域的降水量，季节性和趋势下喜马拉雅（LH），大喜马拉雅（GH）和喀喇昆仑喜马拉雅（KH）。对温度数据也进行了类似的比较，但仅对05个数据集进行了比较。APHRODITE，CRU-TS，PGF，由于TMPA和GPCC仅是降水数据集，因此为UDEL和ERA-I。这项研究是首次尝试，其中原位观测包括来自海拔5000 m amsl（07 ob ...
