Multiregional Satellite Precipitation Products Evaluation over Complex Terrain [PDF]

open access: yes, 2016
An extensive evaluation of nine global-scale high-resolution satellite-based rainfall (SBR) products is performed using a minimum of 6 years (within the period of 2000-13) of reference rainfall data derived from rain gauge networks in nine mountainous ...

Towards Accurate Flood Forecasting: Integrating Satellite Data, Hydrological Modeling, and Deep Learning

open access: yesJournal of Flood Risk Management, Volume 18, Issue 4, December 2025.
ABSTRACT In hydrologic modeling, forecasting peak floods is a complex and high‐priority task, particularly in regions with limited in situ observations. This research investigates the potential of utilizing satellite‐based precipitation products with near real‐time updates (NRT‐SbPP), together with deep learning, to improve peak flow estimation and ...

La Niña Impacts on Southeastern African Climate: The Influence of Event Duration

open access: yesInternational Journal of Climatology, Volume 45, Issue 14, 30 November 2025.
ABSTRACT The multiyear La Niña event of 2020–2023, which brought with it several climate disasters across the globe, sparked both mainstream and scientific interest in La Niña events, which typically have received less attention than El Niño. In southern Africa, there is a general expectation in the scientific community and among user groups that La ...

Uncovering Rainfall Trend Discrepancies in Brazil (1983–2022): Insights From Ground‐Based and Blended Datasets

open access: yesInternational Journal of Climatology, Volume 45, Issue 13, 15 November 2025.
Performance comparison between ground‐based (BR‐DWGD), satellite‐based (CHIRPS and PERSIANN‐CDR) and reanalysis (ERA5‐Land and MERRA‐2) rainfall datasets highlighted challenges in interpreting rainfall trends due to limitations of datasets’ methodologies, the scope of the effects of climate change, and the researchers' understanding.

Potential of using remote sensing techniques for global assessment of water footprint of crops [PDF]

open access: yes, 2010
Remote sensing has long been a useful tool in global applications, since it provides physically-based, worldwide, and consistent spatial information. This paper discusses the potential of using these techniques in the research field of water management ...

Toward a methodological toolkit to mitigate the evaluator's dilemma: Assessing pastoralist rangelands management in Northern Tanzania

open access: yesConservation Science and Practice, Volume 7, Issue 11, November 2025.
We demonstrate how directed acyclic graphs and item response theory can help mitigate the evaluator's dilemma—that of identifying project impacts in contexts of limited funding and absence of an ideal study design. In our case study, using these methods, we find that the perceived quality of rangeland commons governance after project completion is ...

EVALUATION OF TRMM-3B42V7 AND PERSIANN-CDR DAILY-PRECIPITATION PRODUCTS FOR THE SOUTHERN SLOPES OF ALBORZ MOUNTAINS, IRAN [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
The density of rain gauges in many regions is lower than standard. Therefore, there are no precise estimates of precipitation in such regions. Today the use of satellite data to overcome this deficiency is increasing day to day.

A Thermodynamically Informed Precipitation Retrieval Method Based on FY‐4A/AGRI Multi‐Channel Infrared Observations Over Complex Terrain

open access: yesGeophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Accurate precipitation monitoring is critical for hazard risk mitigation in regions characterized by complex terrain. To address these challenges, this study proposes a two‐stage framework that integrates thermodynamic controls, including cloud top brightness temperature (BT) from FengYun‐4A geostationary Multi‐Infrared observations And ...
