Rainfall Consistency, Variability, and Concentration over the UAE: Satellite Precipitation Products vs. Rain Gauge Observations

Recent advancements in remote sensing have led to the development of several useful technologies that would significantly improve our understanding atmospheric sciences. The ability identify conditions and determine possibility intensity rainfall over a specific location represents one most important advantages. However, use measure precipitation arid regions has revealed significant disparities due mixture climatic terrestrial factors. objective this study is assess consistency, variability, concentration UAE using four multi-satellite products, namely CHIRPS, CMORPH, GPM-IMERG, PERSIANN-CDR, considering daily data from 50 rain gauges for period 2004 through 2020. area divided into various geomorphological accuracy products different regions. Results reveal with finer spatial resolution such as CHIRPS CMORPH are better terms annual average values. GPM-IMERG demonstrated POD values 0.80 0.78, respectively, while PERSIANN-CDR showed 0.72 0.44, respectively. correlation error estimate analysis performance varies each region. registered highest 0.8 East Coast, other it could not correlate well. IMERG were able exhibit good value (up 0.8) gauge observations. Precipitation variability alternative data. It concluded multiple hydro-climatological measures should be utilized effectiveness satellite select best product studies.
