The Workshop on Modelling Meltwater in Snow and Firn: Processes, Validation, Intercomparison and Model uses of Optical Remotely Sensed Data will be held at the Geological Survey of Denmark and Greenland (GEUS), Øster Voldgade 10, DK-1350 Copenhagen K. it is the second workshop held as part of Danish Council for Independent Research (DFF) Natural Sciences program (FNU) project 4002-00234: Understanding and predicting non-linear change in the permeability of Greenland firn and has a special session co-sponsored by the ESA Scientific Exploitation of Operational Missions (SEOM) Sentinel-3 for Science, Land Study 1: SNOW.
The purpose of the workshop is to:
Welcomes, for example, model considerations of water availability vs. percolation rate vs. refreezing rate to explore the importance of heterogeneous percolation modelling in polar firn; fine-and-local scale/detailed modeling with possible suggestions to including bulk effects in larger-scale models; inclusion of piping (for instance, by "skipping layers" during percolation) in distributed or single-column models; inclusion of horizontal water motion in snow and firn, i.e. between grid cells.
Will focus on discussions of useful model validation metrics and aim to compile observational datasets that may be used to validate the above processes.
Will discuss and formulate a protocol for a meltwater retention model intercomparison project.
Serves an ESA Sentinel-3 for Science Land Study: Snow "S-3-Snow" that includes an element to gather and prioritize snow modeller interest and requirements about optical remotely sensed snow parameters (snow extent, albedo, grain size, impurity content, etc.). The ESA study is to engage users of Sentinel-3 snow optical retrievals in 1.) model comparison and/or 2.) data assimilation. The workshop session is to:
The expected outcomes of the workshop are:
We have some financial support, but may ask a modest registration fee. We plan for the workshop to include lunch, morning and afternoon coffee breaks. We are working to raise some financial support for early-career scientists to participate in the workshop. Please indicate at registration whether you will request support.
For accommodation, a range of hotels and hostels exist near the workshop location. Public transport is very efficient, including bike rental. Booking these early is recommended due to high demand that may occur.
