Precipitation Trends Over The Indus Basin, Nir Krakauer, Tarendra Lakhankar, Ghulam Hussain Dars Sep 2019

Precipitation Trends Over The Indus Basin, Nir Krakauer, Tarendra Lakhankar, Ghulam Hussain Dars

Publications and Research

A large population relies on water input to the Indus basin, yet basinwide precipitation amounts and trends are not well quantified. Gridded precipitation data sets covering different time periods and based on either station observations, satellite remote sensing, or reanalysis were compared with available station observations and analyzed for basinwide precipitation trends. Compared to observations, some data sets tended to greatly underestimate precipitation, while others overestimate it. Additionally, the discrepancies between data set and station precipitation showed significant time trends in many cases, suggesting that the precipitation trends of those data sets were not consistent with station data. Among the ...

Generating Multi-Sensor Precipitation Estimates Over Radar Gap Areas, Shayesteh E. Mahani, Reza Khanbilvardi

Publications and Research

Generating a multi-sensor precipitation product over radar gap area is the objective of the present study. A merging approach is developed to improve Satellite-based Precipitation Estimates (SPE) by merging with ground-based Radar Rainfall (RR) estimates because remote satellites are the only source that can collect information from areas where are inaccessible by ground-based radar and/or rain gauge networks. The merging algorithm is capable of extending radar information from pixels with available RR to their neighboring pixels with no radar information by merging RR with SPE, which is, usually, available for all pixels. SPE is combined with RR using the ...
