Seminar by Kristoffer Aalstad, Researcher, Department of Geosciences, University of Oslo, entitled:
Model inversion using data assimilation to learn from Earth observations in cold regions
Abstract
Mapping from observations to the states that may have generated them falls under the umbrella of inverse problems. The abundance of these problems has fueled the development of Data Assimilation (DA) schemes that fuse uncertain information from models and observations. Notable applications include atmospheric reanalysis and numerical weather prediction. The added value that DA can bring to Earth Observations (EO) as a generalized retrieval algorithm is much less appreciated. We present two different inverse problems, snowpack reconstruction using satellite data and surface flux inversion using drone swarms, showing how DA helps us to make the most out of emerging EO in cold regions.

About the seminar series
GeoHyd Lunch Seminars are for the time being fully-digital, following the corona guidelines.
This seminar is offered by the Section for Geography and Hydrology, Dept. of Geosciences, University of Oslo. The GEOHYD-seminars are announced as lunch seminars so bring your lunch if you want to.
The seminars are open for everyone interested, and especially students are welcome.
