Stabilized nonconforming finite element methods for data assimilation in incompressible flows [PDF]
, 2016 We consider a stabilized nonconforming finite element method for data assimilation in incompressible flow subject to the Stokes' equations. The method uses a primal dual structure that allows for the inclusion of nonstandard data.

The Assimilation of Envisat data (ASSET) project [PDF]
Atmospheric Chemistry and Physics, 2006 Abstract. This paper discusses the highlights of the EU-funded "Assimilation of Envisat data" (ASSET) project, which has involved assimilation of Envisat atmospheric constituent and temperature data into systems based on Numerical Weather Prediction (NWP) models and chemical transport models (CTMs).

Fundamentals of Data Assimilation [PDF]
, 2016 Abstract. This article lays out the fundamentals of data assimilation as used in biogeochemistry. It demonstrates that all of the methods in widespread use within the field are special cases of the underlying Bayesian formalism. Methods differ in the assumptions they make and information they provide on the probability distributions used in Bayesian ...

Prediction of Sunspot Cycles by Data Assimilation Method [PDF]
, 2008 Despite the known general properties of the solar cycles, a reliable forecast of the 11-year sunspot number variations is still a problem. The difficulties are caused by the apparent chaotic behavior of the sunspot numbers from cycle to cycle and by the ...

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.

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
