CRA-LICOM: a global high-frequency atmospheric and oceanic temporal gravity field product (2002–2024) [PDF]

Modeling sub-daily mass changes, dominated by the atmosphere and the oceans, is a fundamental requirement for nearly all existing terrestrial or space-borne geodetic observations to perform signal separation.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

On the role of the Southern Ocean in the global carbon cycle and atmospheric CO2 change

, 2010
Uncertainty about the causes of glacial-interglacial CO2 variations demonstrates our incomplete grasp of fundamental processes that govern our climate and thus one of the foremost problems in palaeoceanography and Earth System Science regards the ...

Multi‐Decadal Skill Variability in Predicting the Spatial Patterns of ENSO Events

Geophysical Research Letters
Seasonal hindcasts have previously been demonstrated to show multi‐decadal variability in skill across the twentieth century in indices describing El‐Niño Southern Oscillation (ENSO), which drives global seasonal predictability.

Effects of aerosol in simulations of realistic shallow cumulus cloud fields in a large domain [PDF]

Atmospheric Chemistry and Physics, 2019
Previous study of shallow convection has generally suffered from having to balance domain size with resolution, resulting in high-resolution studies which do not capture large-scale behaviour of the cloud fields.

Methods for assimilation of observational data in problems of the physics of the atmosphere and the ocean [PDF]

Известия Российской академии наук. Физика атмосферы и океана, 2019
In this paper we review and analyze approaches to data assimilation in geophysical hydrodynamics problems, starting with the simplest successive schemes of assimilation and ending with modern variational methods. Special attention is paid to the the study of the problem of variational assimilation in the weak formulation and construction of covariance ...

Resolution, physics and atmosphere–ocean interaction – How do they influence climate model representation of Euro-Atlantic atmospheric blocking? [PDF]

Tellus A: Dynamic Meteorology and Oceanography, 2017
Atmospheric blocking events are known to locally explain a large part of climate variability. However, despite their relevance, many current climate models still struggle to represent the observed blocking statistics. In this study, simulations of the global climate model EC-Earth are analysed with respect to atmospheric blocking. Seventeen simulations

Atmospheric Water Harvesting Through Polymer Hydrogel Sorbents: Materials Chemistry, Design Strategies, and Applications

Advanced Science, EarlyView.
Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Chemical cycling and deposition of atmospheric mercury in polar regions: review of recent measurements and comparison with models

, 2018
Mercury (Hg) is a worldwide contaminant that can cause adverse health effects to wildlife and humans. While atmospheric modeling traces the link from emissions to deposition of Hg onto environmental surfaces, large uncertainties arise from our incomplete
