Uncertainty assessment and applicability of an inversion method for volcanic ash forecasting [PDF]
Atmospheric Chemistry and Physics, 2017 Significant improvements in the way we can observe and model volcanic ash clouds have been obtained since the 2010 Eyjafjallajökull eruption. One major development has been the application of data assimilation techniques, which combine models and ...

Effects of a priori profile shape assumptions on comparisons between satellite NO2 columns and model simulations [PDF]
Atmospheric Chemistry and Physics, 2020 A critical step in satellite retrievals of trace gas columns is the calculation of the air mass factor (AMF) used to convert observed slant columns to vertical columns. This calculation requires a priori information on the shape of the vertical profile.

Top-down estimates of black carbon emissions at high latitudes using an atmospheric transport model and a Bayesian inversion framework [PDF]
Atmospheric Chemistry and Physics, 2018 This paper presents the results of BC inversions at high northern latitudes (> 50° N) for the 2013–2015 period. A sensitivity analysis was performed to select the best representative species for BC and the best a priori emission ...

Knowledge of Necessity: Logical Positivism and Kripkean Essentialism [PDF]
, 2008 By the lights of a central logical positivist thesis in modal epistemology, for every necessary truth that we know, we know it a priori and for every contingent truth that we know, we know it a posteriori.

Space-time adaptive finite elements for nonlocal parabolic variational inequalities [PDF]
, 2019 This article considers the error analysis of finite element discretizations and adaptive mesh refinement procedures for nonlocal dynamic contact and friction, both in the domain and on the boundary. For a large class of parabolic variational inequalities

A comprehensive evaluation of the use of Lagrangian particle dispersion models for inverse modeling of greenhouse gas emissions [PDF]
Geoscientific Model Development, 2022 Using the example of sulfur hexafluoride (SF6), we investigate the use of Lagrangian particle dispersion models (LPDMs) for inverse modeling of greenhouse gas (GHG) emissions and explore the limitations of this approach.
