Data sets

Circumpolar mid-winter thaw and refreeze based on fusion of Metop ASCAT and SMOS A. Bartsch, H. Bergstedt, G. Pointner, X. Muri, and K. Rautiainen https://doi.org/10.5281/zenodo.7575927

Short summary

Rain-on-snow (ROS) events occur across many regions of the terrestrial Arctic in mid-winter. In extreme cases ice layers form which affect wildlife, vegetation and soils beyond the duration of the event. The fusion of multiple types of microwave satellite observations is suggested for the creation of a climate data record. Retrieval is most robust in the tundra biome, where records can be used to identify extremes and the results can be applied to impact studies at regional scale.
