Assessment of CHIRPS and PERSIANN-CDR products for meteorological drought monitoring and future trends in East Africa

Environmental Research: Climate
Abstract The satellite precipitation products provide a reliable alternative data source for real-time drought monitoring in developing countries. Therefore, it is important to quantify the excellent satellite precipitation products for drought estimation.

Can Global Products Capture Precipitation Variability in the Galápagos Islands? An Assessment Based on Climatic Time‐Series Components

Meteorological Applications, Volume 32, Issue 4, July/August 2025.
We combined conventional validation and climatic time‐series component analysis to evaluate five global precipitation products in the Galápagos Islands. This integrated approach reveals not only overall accuracy but also how well each product captures seasonality, anomalies, and long‐term trends.

Global Evaluation of the Wettest Days Contributing to 50% of Annual Precipitation (WD50)

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Amid intensifying global warming, precipitation regimes become increasingly concentrated on the wettest days. Yet, there remains limited research at the global scale analyzing how half of the annual precipitation falls predominantly on these days.

Evaluation and Hydrological Application of CMADS against TRMM 3B42V7, PERSIANN-CDR, NCEP-CFSR, and Gauge-Based Datasets in Xiang River Basin of China [PDF]

Water, 2018
Satellite-based and reanalysis precipitation products provide a practical way to overcome the shortage of gauge precipitation data because of their high spatial and temporal resolution. This study compared two reanalysis precipitation datasets (the China Meteorological Assimilation Driving Datasets for the Soil and Water Assessment Tool (SWAT) model ...

Satellite‐Derived Productivity Outputs for Land Degradation Assessment Vary With Biome and Rainfall

Land Degradation &Development, Volume 36, Issue 9, Page 2913-2927, 30 May 2025.
ABSTRACT Estimates of the extent of land degradation vary dramatically. To quantify the extent and location of land degradation globally, the United Nations Convention to Combat Desertification (UNCCD) asks member countries to report on land degradation every four years, providing crucial baseline and change data.

Characteristics and atmospheric drivers of large‐scale agrometeorologically relevant dry spells in sub‐seasonal to seasonal timescales over Zimbabwe

Meteorological Applications, Volume 32, Issue 2, March/April 2025.
This study presents a crop‐centric approach to analysing dry spell impacts, using the Water Requirement Satisfaction Index (WRSI). Leveraging this metric, it further identifies and characterizes large‐scale agrometeorologically relevant dry spells (LARDS) in Zimbabwe. The study's findings demonstrate that meteorological guidance enhances yield and link

A Cluster‐Based Data Assimilation Approach to Generate New Daily Gridded Time Series Precipitation Data in the Himalayan River Basins

Water Resources Research, Volume 61, Issue 1, January 2025.
Abstract Recent studies show variations in precipitation‐gridded data set accuracy with changing geographical parameters. Ensemble precipitation products, combining diverse data sets, offer global‐scale effectiveness, but applying them to regional studies, particularly in small to medium‐sized sub‐basins, presents challenges in addressing precipitation

Synoptic Patterns and Effects of Topography on Occurrences of Heavy Rainfall in Northwest Vietnam

Advances in Meteorology, Volume 2025, Issue 1, 2025.
Accurate forecasting of local heavy rainfall distribution over Northwest Vietnam is challenging due to the regions’s complex rainfall processes and topography. In this study, effect of the Hoang Lien Son (HLS) Mountain range on synoptic‐dynamic processes associated with the heavy rainfall were analyzed to quantify the relationship with the local ...
