COSMIC-2 RO Profile Ending at PBL Top with Strong Vertical Gradient of Refractivity

open access: yesRemote Sensing, 2022
The Formosa Satellite-7/Constellation Observing System for Meteorology, Ionosphere, and Climate-2 (Satellite-7/COSMIC-2), which was successfully launched on 25 June 2019, provides dense radio occultation (RO) observations over the tropics and subtropics.

On sequential multiscale inversion and data assimilation [PDF]

open access: yes, 2018
Multiscale approaches are very popular for example for solving partial differential equations and in many applied fields dealing with phenomena which take place on different levels of detail.

Data assimilation [PDF]

open access: yes
Data assimilation get increasingly important in experimental fluid dynamics. The field of applications is expanding and the methods are becoming more differentiated. From data analysis, error reduction and lower order modelling to physical constraint measurement data interpolation.

Stabilized nonconforming finite element methods for data assimilation in incompressible flows [PDF]

open access: yes, 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.

Bias Characteristics of COSMIC RO Data within Clouds Based on Different Background Fields

open access: yesGaoyuan qixiang, 2023
The Global Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) radio occultation (RO) from 2007 to 2009 were collocated with the CloudSat nadir-pointing cloud profiling radar (CPR) in time and space in this study.We ...

Assimilating SAR-derived water level data into a hydraulic model: a case study [PDF]

open access: yes, 2011
Satellite-based active microwave sensors not only provide synoptic overviews of flooded areas, but also offer an effective way to estimate spatially distributed river water levels.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
