Contrasting associations of sea‐ice meltwater and meteoric water with nitrogen uptake patterns in the summer Cosmonaut Sea, Antarctica

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract Nitrogen uptake by phytoplankton influences Southern Ocean productivity and carbon export, but how source‐resolved meltwater is associated with nitrate and ammonium use remains unclear. Here, 15N tracer incubations and a δ18O‐salinity mixing model were combined to examine nitrogen uptake in the early‐summer Cosmonaut Sea.

New Possibilities for Geophysical Parameter Retrievals Opened by GCOM-W1 AMSR2 [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
A new approach to retrieve sea surface wind speed (SWS) in tropical cyclones (TCs) from the Advanced Microwave Scanning Radiometer 2 (AMSR2) data is presented. Analysis of all six AMSR2 C- and X-band channel measurements over TCs is shown to efficiently help to separate the rain contribution. Corrected measurements at 6.9 and 10.65 GHz are then used to

Satellite Soil Moisture Validation Using Hydrological SWAT Model: A Case Study of Puerto Rico, USA

Hydrology, 2017
Soil moisture is placed at the interface between land and atmosphere which influences water and energy flux. However, soil moisture information has a significant importance in hydrological modelling and environmental processes.

Observational Validation of Boundary‐Layer Cloud Regimes in Arctic Cold Air Outbreaks

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Arctic cold air outbreaks (CAOs) produce low‐level cloud patterns influencing the surface radiative balance. The stability parameter −H/L ${-}H/L$ (boundary‐layer height over Monin‐Obukhov length) is theorized to distinguish shear‐driven roll convection from buoyancy‐driven cellular convection, but observational evidence remains limited. Using

Tuvaijuittuq: The Last Refuge of Multiyear Ice (MYI) Is Becoming Increasingly Open

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Tuvaijuittuq is currently the largest in a series of Marine Protected Areas (MPAs) in the Canadian Arctic. The remoteness, inaccessibility and paucity of environmental data creates challenges in understanding and establishing conservation management strategies of this unique multiyear ice (MYI)‐dominated region.

The OCO‐2 and OCO‐3 ACOS Version 11 XCO2 Data Products: A Benchmark Record for Space‐Based Global Carbon Cycle Research

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract NASA's Orbiting Carbon Observatory‐2 (OCO‐2) and OCO‐3 have been observing Earth's atmosphere from space since September 2014 and August 2019, respectively. The version 11 (v11) Atmospheric Carbon Observations from Space (ACOS) Level 2 full physics (L2FP) retrieval algorithm has been used to provide estimates of the column‐averaged dry‐air ...

Infrared‐Guided Super‐Resolution of Remotely Sensed Passive Microwave Sea Surface Temperature

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract High‐resolution sea surface temperature (SST) is essential for weather forecasting and climate applications. Passive microwave (MW) SST offers largely cloud‐penetrating coverage but is coarse and spatially smoothed, whereas infrared (IR) SST resolves fine‐scale structures but is frequently cloud‐obscured.
