Implementation of a Rainfall Normalization Module for GSMaP Microwave Imagers and Sounders

Remote Sensing, 2022
This paper introduces the Method of Microwave Rainfall Normalization (MMN) for the Global Satellite Mapping of Precipitation (GSMaP) algorithm in its latest version (V05, algorithm version 8), released in December 2021. The method aims to mitigate the discrepancy of GSMaP rainfall estimates among passive microwave (PMW) imagers/sounders (MWIs/MWSs) due

A Machine Learning Approach for Improving the Accuracy of Gridded Precipitation With Uncertainty Quantification

International Journal of Climatology, Volume 46, Issue 1, January 2026.
A novel machine learning (ML) approach combining extreme gradient boosting with quantile regression is used to create Vietnam Precipitation with Uncertainty (VNpu). Our VNpu dataset outperforms individual input products, benchmark interpolation methods and an existing gauge‐based product, particularly for heavy and extreme rainfall events. ABSTRACT The

Variability in Updraft Mass Flux Across the Top of the Atmospheric Boundary Layer Over the Tropical Western North Pacific Associated With a Tropical Depression

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.
Abstract Over tropical oceans, cumulus convection is triggered by updrafts from the atmospheric boundary layer (BL). Given mutual interactions between cumulus convective ensembles and synoptic‐ to global‐scale atmospheric phenomena, it seems important to quantitatively evaluate the updraft on spatiotemporal scales relevant to the interactions and ...

Rain Rate Retrieval Algorithm for Conical-Scanning Microwave Imagers Aided by Random Forest, RReliefF, and Multivariate Adaptive Regression Splines (RAMARS) [PDF]

, 2015
This paper proposes a rain rate retrieval algorithm for conical-scanning microwave imagers (RAMARS), as an alternative to the NASA Goddard profiling (GPROF) algorithm, that does not rely on any a priori information.

Impact of Land Use Change and Drought on the Net Emissions of Carbon Dioxide and Methane From Tropical Peatlands in Southeast Asia

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Peat decomposition is progressing in Southeast Asia due to lowered groundwater levels (GWL) caused by drainage. Additionally, droughts during El Niño events significantly lower the GWL, the main environmental factor that controls greenhouse gas (GHG; carbon dioxide (CO2) and methane) emissions in peatlands.

Applications of Attention‐Enhanced CNN Models to Regional Precipitation Downscaling

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Precipitation downscaling is essential for generating high‐resolution data from coarse‐resolution global climate models and assessing the environmental impacts of climate change at regional and local scales. Convolutional Neural Networks (CNNs) are an emerging critical deep‐learning technique that promises significant improvements over other ...
