The synergy of assimilating visible and infrared radiances and radar observations
Quarterly Journal of the Royal Meteorological Society, EarlyView.Evaluation of the analysis error for different cloud conditions revealed that combined assimilation can mitigate the ambiguity of individual visible and infrared channels. The combined assimilation of visible and infrared radiances can avoid the shortcomings of assimilating only visible or infrared radiances in convective‐scale numerical weather ...

Model‐based optimization of source locations for 3D acoustic seismic full‐waveform inversion
Geophysical Prospecting, Volume 71, Issue 1, Page 3-16, January 2023., 2023 Abstract Besides classical imaging techniques, full‐waveform inversion is an increasingly popular method to derive elastic subsurface properties from seismic data. High‐resolution velocity models can be obtained, and spatial sampling criteria are less strict than for imaging methods, because the entire information content of the seismic waveforms is ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.Increasing the resolution by the order of a few kilometres in global climate simulations causes no substantial changes to boundary‐layer properties and processes over land. Some global changes are detected that indicate circulation changes, and small changes to the boundary‐layer depth and structure are found over land in the Tropics.

Geophysical Prospecting, Volume 71, Issue 1, Page 17-28, January 2023., 2023 Abstract Pore‐pressure depletion causes changes in the triaxial stress state. Pore‐pressure depletion in a flat reservoir, for example, can be reasonably approximated as uniaxial compaction, in which the horizontal effective stress change is smaller than the vertical effective stress.

Spatial variability of near‐surface air temperature in the Copernicus Arctic regional reanalysis
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study investigates spatial variability of near‐surface air temperature in the European Arctic, using the Copernicus Arctic Regional Reanalysis data from 1991 to 2022. Geographical features and seasonal changes strongly influence spatial variability of air temperature.

Geophysical Prospecting, Volume 71, Issue 2, Page 292-321, February 2023., 2023 Abstract A Bayesian inversion methodology is proposed that inverts angle‐stacked 4D seismic maps to changes in pressure, water saturation and gas saturation. The inversion method is applied to data from a siliciclastic reservoir in the west of Shetlands, UK continental shelf.

Data assimilation errors due to incomplete accounting of balanced versus unbalanced moisture
Quarterly Journal of the Royal Meteorological Society, EarlyView.We investigate data assimilation strategies with moisture and assess the impact of accounting for moisture's balanced and unbalanced components. To illustrate the main ideas, examples are presented using a simple model consisting of linear, moist, shallow‐water equations with stochastic forcing.

Exoplanet Geology: What can we learn from current and future observations? [PDF]
arXivNearly 30 years after the discovery of the first exoplanet around a main sequence star, thousands of planets have now been confirmed. These discoveries have completely revolutionized our understanding of planetary systems, revealing types of planets that do not exist in our solar system but are common in extrasolar systems, and a wide range of system ...

GeosciencesThe Luk-Ulo Melange Complex (LMC) is characterized by a chaotic assemblage of mixed rocks with a block-in-matrix fabric. The exposed blocks consist of various scattered rock types, trending in an ENE-WSW direction. In the case of Mt.
