Spatial Downscaling and Simulation of TRMM Data at High Altitudes — A Case Study of Lhasa River by DAWA Ciren, ZHAO Keke, GU Yu, LUO Xiaoyu, CIWANG Dunzhu

“…As measured precipitation data are often lacking at high altitudes,remote sensing data by satellites could compensate for the shortage of traditional observation.This paper takes the Lhasa River basin as the study area and makes an in-depth analysis of the relationship between precipitation,vegetation,and temperature in this basin.On this basis,the multiple linear regression,residual analysis,and inverse distance weighting (IDW) of spatial interpolation are employed to spatially downscale the TRMM 3B43V7 data that overestimates the precipitation in the study area by about 29% and has a spatial resolution of 0.25°×0.25° to 0.05°×0.05°.Given the measured data of stations,the downscaled data is further revised.The accuracy of the final high-quality precipitation dataset is greatly improved in most regions of the Lhasa River basin,and the dataset can provide basic statistical support for research on hydrology and water resources at high altitudes.…”

Improving Knowledge about Snow by Crossing Qualitative and Quantitative Data from the Everest Region (Nepal) by Ornella Puschiasis, Marie Savéan, Pierre Chevallier, Joëlle Smadja, Olivia Aubriot, François Delclaux

“…To get a better understanding of solid precipitation and how it has evolved over the last decades, and thus to improve our knowledge of hydro-climatic variations, we crossed quantitative data (measured, spatialised and simulated) produced from work in hydrology, with qualitative data (field interviews) derived from work in human geography. …”

Annual Observations of Climatic Impacts in the Songhua River Basin, China by Xiaocheng Song, Liu Jing

“…The relationship between rivers and the atmosphere is particularly significant for heat fluxes and varies with the meteorology and hydrology. In this study, based on annual observation data from the Songhua River Basin (Harbin, China), a regression and a stochastic model were used to analyze the relationship of the atmosphere-river daily maximum temperatures and evaluate the heat fluxes. …”
