Data Driven Reconstruction of Upper Ocean Profiles for Improved State Estimation in the Philippine Sea

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Despite significant advances in observational systems such as the global Argo array of autonomous profiling floats, the spatiotemporal coverage of subsurface ocean observations remains limited compared to the dense data provided by satellite platforms. This study develops a data‐driven framework to reconstruct synthetic profiles of upper ocean

Learning 2D Shallow Water Equations With Physics‐Informed Neural Operator Networks

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract This study investigates the application of Physics‐Informed Neural Operators (PINOs) for solving the two‐dimensional shallow water equations (2D SWE) in the context of flood modeling. Unlike Physics‐Informed Neural Networks (PINNs), which require retraining for each new initial or boundary condition (BC), PINOs learn the solution operator ...

Assimilation of All‐Sky TROPICS Constellation Radiance Data in the NASA Goddard Earth Observing System (GEOS)

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This study examines the impact of assimilating all‐sky microwave radiances from the Time‐Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission within the NASA Global Earth Observing System (GEOS) data assimilation and forecasting framework based on the Gridpoint Statistical ...

A computational method for left-adjointness

In this work, we investigate an effective method for showing that functors between categories are left adjoints. The method applies to a large class of categories, namely locally finitely presentable categories, which are ubiquitous in practice and include standard examples like Set, Grp, etc.

Air Quality Forecasts With Observation‐Based Scaling of Anthropogenic Emissions for Urban Agglomerations

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Air quality forecasts are essential to support decision‐making in urban agglomerations, where millions of people are exposed to high levels of pollution. However, these forecasts are often limited by uncertainties in anthropogenic emissions, especially in large urban agglomerations where no dedicated operational system exists.

Vertical Momentum Flux at 0°N, 140°W: Unresolved Internal Waves and Implications for Cold Tongue SST

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract The Equatorial Pacific Cold Tongue is critical to the Bjerknes feedback driving the El Niño‐Southern Oscillation (ENSO), yet simulating Cold Tongue sea surface temperature (SST) remains difficult. Historical turbulence observations reveal a vertical momentum flux deficit in the zonal momentum budget at 0°N, 140°W.
