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 ...

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.

Evaluation of GSMaP Precipitation Estimates over the Contiguous United States

Journal of Hydrometeorology, 2010
Abstract Precipitation estimates from the Global Satellite Mapping of Precipitation (GSMaP) project are evaluated over the contiguous United States (CONUS) for the period of 2005–06. GSMaP combines precipitation retrievals from the Tropical Rainfall Measuring Mission satellite and other polar-orbiting satellites, and interpolates them ...

COMPARISON ANALYSIS OF HIMAWARI 8, CHIRPS AND GSMaP DATA TO DETECT RAIN IN INDONESIA

Jurnal Meteorologi dan Geofisika, 2023
The need for rainfall data, especially for areas where the number of observation stations is not very close, is very important for local climate analysis activities. This data need can be met, one of which is from remote sensing data, such as Himawari 8.

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 ...

Tropical Cyclone Intensity Change and Axisymmetricity Deduced from GSMaP

Monthly Weather Review, 2017
The relationship of tropical cyclone (TC) future intensity change to current intensity and current axisymmetricity deduced from hourly Global Satellite Mapping of Precipitation (GSMaP) data was investigated. Axisymmetricity is a metric that correlates positively with the magnitude of the axisymmetric component of the rainfall rate and negatively with ...

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

Journal 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 ...

Vertical Velocity and Diabatic Heating Top‐Heaviness in the Convective Evolution Over Tropical Oceans

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 19, 16 October 2025.
Abstract Convective heating and vertical motion are closely linked to each other and follow similar evolutionary paths over their convective life cycle. It has not yet been extensively explored, using observation, how such a collaborative evolution changes systematically from region to region over tropical oceans.
