Seasonal forecasting of subsurface marine heatwaves
Communications Earth & Environment, 2023 Marine heatwaves damage marine ecosystems and services, with effects identified mostly below the ocean surface. To create a truly user-relevant detection system, it is necessary to provide subsurface forecasts.

Ensemble-based kernel learning for a class of data assimilation problems with imperfect forward simulators [PDF]
PLoS ONE 14(7): e0219247, 2019, 2019 Simulator imperfection, often known as model error, is ubiquitous in practical data assimilation problems. Despite the enormous efforts dedicated to addressing this problem, properly handling simulator imperfection in data assimilation remains to be a challenging task.

Data assimilation in a multi-scale model [PDF]
, 2017 Data assimilation for multi-scale models is an important contemporary research topic. Especially the role of unresolved scales and model error in data assimilation needs to be systematically addressed.

The Onsager--Machlup functional for data assimilation [PDF]
, 2017 When taking the model error into account in data assimilation, one needs to evaluate the prior distribution represented by the Onsager--Machlup functional.

A multiscale method for data assimilation [PDF]
Computational Geosciences, 2018 In data assimilation problems, various types of data are naturally linked to different spatial resolutions (e.g., seismic and electromagnetic data), and these scales are usually not coincident to the subsurface simulation model scale. Alternatives like upscaling/downscaling of the data and/or the simulation model can be used, but with potential loss of

Super-resolution data assimilation
Ocean Dynamics, 2022 AbstractIncreasing model resolution can improve the performance of a data assimilation system because it reduces model error, the system can more optimally use high-resolution observations, and with an ensemble data assimilation method the forecast error covariances are improved.

FEBS Letters, EarlyView.Spot‐14 and Spot‐14R play distinct roles in regulating metabolism in brown and beige adipocytes. While both influence lipid and glucose pathways, Spot‐14 uniquely controls thermogenic gene expression. This dual regulation balances energy storage and heat production, highlighting potential therapeutic targets for obesity and metabolic disorders. Spot 14

How Asian slum emissions impact local microclimates in polluted air masses
Atmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022 Cook stove emissions over urban sprawl in South India and expected microphysical implications. Combustion‐mediated soot and black carbon from biomass burning in shantytowns modulate the local cloud cover. Abstract Urban sprawl comprising densely populated slums over South Asian cities yields copious amounts of soot and black carbon from archaic cooking

Consistent assimilation of multiple data streams in a carbon cycle data assimilation system [PDF]
Geoscientific Model Development, 2016 Abstract. Data assimilation methods provide a rigorous statistical framework for constraining parametric uncertainty in land surface models (LSMs), which in turn helps to improve their predictive capability and to identify areas in which the representation of physical processes is inadequate.

Development and Evaluation of a New Method for AMSU-A Cloud Detection over Land
Remote Sensing, 2021 Satellite data are the main source of information for operational data assimilation systems, and Advanced Microwave Sounding Unit-A (AMSU-A) data are one of the types of satellite data that contribute most to the reduction of numerical forecast errors ...
