IMERG is a global satellite-based precipitation dataset, produced by NASA. It has provided valuable rainfall information to facilitate the design or the operation of the disaster and risk management worldwide. In operation, NASA offers three types of IMERG Level 3 (L3) products, with different levels of trade-offs in terms of time latency and accuracy.

Spatial downscaling of IMERG precipitation estimates using statistical techniques
2023The aim of this study was to spatially downscale the Precipitation Estimates (PEs) from the Global Precipitation Measurement (GPM) mission, using the Integrated Multi-satellite Retrievals for GPM (IMERG), over a complex region in Greece. For this purpose, the Multivariate Linear Regression (MLR) and the Residual Correction (RC) techniques were utilized,

A Spatial-Temporal Extreme Precipitation Database from GPM IMERG
2021Extreme precipitation events (EPEs) have the potential to create catastrophic flooding, landslides, and infrastructure damage. We diagnose the spatial and temporal characteristics of EPEs by using the Integrated Multi-SatellitE Retrievals for Global Precipitation Measurement mission (GPM; IMERG) precipitation estimates to construct spatial-temporal (xy-

IMERG-E and IMERG-L: A Comprehensive Evaluation of the Medicane Daniel in Thessaly, Greece
On 4 September 2023, the area of Thessaly (Greece) experienced a catastrophic flood as a result of the Daniel hurricane sequence. This severe phenomenon is characterized by extreme rainfall records ranging from 305 mm to 1096 mm between 4 and 7 September, causing severe damage to infrastructure, agriculture and buildings.Evangelos Leivadiotis +2 more

Uncertainties associated with the IMERG Multi-Satellite precipitation product
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016This study compares the NASA Integrated Multi-satellitE Retrievals for GPM (IMERG) satellite precipitation product with the satellite radar-based GPM Ku-Ka 2ADPR product across the contiguous United States (CONUS) at 0.1° and half-hourly resolution. Results are shown in terms of performance and Taylor's diagrams, which provide a concise description of ...

A Diagnosis of Oceanic Precipitation in IMERG-GMI
Journal of HydrometeorologyAbstract Diagnosing errors in spaceborne oceanic precipitation estimates is difficult due to complicated multisatellite algorithms and limited surface-based measurements. The Global Precipitation Measurement (GPM) mission helps to alleviate these challenges with NASA’s Integrated Multi-satellitE Retrievals for GPM (IMERG) product, which is ...
