Climate-informed cryospheric reanalysis via hierarchical Bayesian data assimilation
Kristoffer Aalstad, Esteban Alonso-González, Joel Fiddes +7
The cryosphere regulates global cycles of water, energy, and carbon, affecting societies and ecosystems. By assimilating observations into models, we can infer the past trajectory…
Evolving beyond collapse: An adaptive particle batch smoother for cryospheric data assimilation
Kristoffer Aalstad, Esteban Alonso-González, Norbert Pirk +3
We present a new adaptive particle-based data assimilation scheme for cryospheric applications that leverages promising developments in importance sampling. The proposed approach s…
Guiding drones by information gain
Alouette van Hove, Kristoffer Aalstad, Norbert Pirk
The accurate estimation of locations and emission rates of gas sources is crucial across various domains, including environmental monitoring and greenhouse gas emission analysis. T…
Using reinforcement learning to improve drone-based inference of greenhouse gas fluxes
Alouette van Hove, Kristoffer Aalstad, Norbert Pirk
Accurate mapping of greenhouse gas fluxes at the Earth's surface is essential for the validation and calibration of climate models. In this study, we present a framework for surfac…
