Participants of the 9th Workshop on Remote Sensing of Land Ice and Snow 2020 in Bern, Switzerland
Call for Papers
The 9th Workshop on Remote Sensing of Land Ice and Snow of the European Association of Remote Sensing Laboratories (EARSeL) was held at the Institute of Geography, University of Bern, Switzerland, from 03 - 05 February 2020.
The cryosphere of the Earth is undergoing dramatic changes. Glaciers are retreating at accelerated rate and snow cover distribution and duration is changing with many significant side-effects (run-off, permafrost, albedo, etc.). Remote Sensing can provide the required data to study these changes of the cryosphere.
This workshop focused on the latest developments in remote sensing of land ice and snow. Presentations were held on all fields of research and applications with the focus on snow and ice as proxy for a changing cryosphere, methods for retrieving cryospheric parameters from various types of remote sensing data, theoretical basis of inversion methods and their application, state of the art of retrieval algorithms, data assimilation of remote sensing data and in situ observations in process models, and current and planned sensors for snow and ice. Half of a day was dedicated to the activities from ESA (CCI+) and EUMETSAT.
Session topics
- Glaciers and Ice Caps
- Snow cover (regional to global scale)
- Snow hydrology
- Snow on sea ice and glaciers
