Status and Plans for GPM and IMERG as They Enter Version 07

2022
<p>As part of the “extended operations” past the 3-year prime mission, the Global Precipitation Measurement (GPM) mission continues to develop improved products, currently rolling out the next Version 07 datasets.  This is later than expected, due to unforeseen complications in upgrading algorithms.

IMERG Run Deep: Can we produce a low-latency IMERG Final run product with a deep learning based prediction model?

2023
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.

Dependence of GPM IMERG products on precipitation intensity in Catalonia.

2023
Satellite precipitation estimates (SPE) offer an excellent way to complement information on the spatio-temporal distribution of precipitation in semi-arid regions, such as Catalonia (NE Spain). The network of automatic weather stations of the Meteorological Service of Catalonia is used to evaluate the performance of the Integrated Multisatellite ...

The added value of IMERG in characterizing rainfall in tropical cyclones

Atmospheric Research, 2018
Abstract Heavy rainfall associated with landfalling tropical cyclones (TCs) is responsible for significant societal and economic impacts. Improved characterization and description of how rainfall during these storms changes as a function of distance from the center of circulation are critical to increase our preparedness against this natural hazard ...

Improved and Consistent Calibration Methodologies for IMERG V08 

NASA’s Integrated Multi-satellitE Retrievals for GPM (IMERG) is a widely used high resolution global precipitation product.  IMERG relies on retrievals from passive microwave (PMW) sensors as the primary input precipitation estimates, so it is vital that they are first homogenously calibrated to the core observatory GMI radiometer and finally to the ...
