Distribution of Plastics of Various Sizes and Densities in the Global Ocean From a 3D Eulerian Model

Journal of Geophysical Research: Oceans, Volume 130, Issue 9, September 2025.
Abstract We study the global transport and distribution of microplastics (MPs) using a three‐dimensional Eulerian model. For the first time, the effects of both particle size and density are accounted for, influencing the vertical transport of MPs, and leading to an advanced understanding of their global distribution.

Regional Land Surface Conditions Developed Using the High‐Resolution Land Data Assimilation System: Challenges Over Complex Orography Himalayan Region

Meteorological Applications, Volume 32, Issue 4, July/August 2025.
High‐resolution land data assimilation system (HRLDAS) simulations at 2 km resolution from 2011 to 2021 over Uttarakhand. HRLDAS outperforms global and regional analyses by capturing finer spatial heterogeneity, with lower soil moisture error and high soil temperature correlation (0.94) against satellite and in situ observations.

CYGNSS Satellite Sampling of Surface Heat Fluxes Across Atmospheric River Life Cycles

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract This study employs CYGNSS data to explore the life cycle of atmospheric rivers (ARs) on a near global scale, focusing on ocean surface turbulent heat flux variations. Using spaceborne measurements matched to different stages of full AR life cycles for the first time, we show declining latent and sensible heat fluxes throughout the AR life ...
