Modeling Meltwater in Snow and Firn: Processes, Validation, Intercomparison and Model uses of Optical Remotely Sensed Data
20-22 September 2017, Copenhagen.
· The workshop starts Wednesday Sep 20 at 12.00, and ends Friday Sep 22 at 12.00.
· A PROMICE 10-year jubilee and reception is planned for the afternoon of Sep 22.
· to present and discuss results on modeling of meltwater retention processes in snow and firn on ice sheets and glaciers;
· to plan and coordinate meltwater retention model development;
· to emphasize optical remote sensing snow parameter data comparison and data assimilation;
· to formulate a protocol for a meltwater retention model intercomparison project (RetMIP)
This is workshop two 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.
1. Snow model development
2. Meltwater retention model validation
3. Meltwater retention model intercomparison project (RetMIP)
4. Optical remote sensing to improve snow models
Session 2 will focus on discussions of useful model validation metrics and aim to compile observational datasets that may be used to validate the above processes.
Session 3 will discuss and formulate a protocol for a meltwater retention model intercomparison project.
Session 4 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:
1. survey and prioritize remotely sensed snow parameter data users’ requirements for global and regional snow information
2. discuss how to enhance methods for estimating snow parameters, either from remote sensing or from modeling, and to evaluate advantages and disadvantages of the different approaches
3. consult users about the utility/interest in other snow products suitable for studying climate-related issues.
Workshop expected outcomes
• a protocol for a retention model intercomparison project (RetMIP) including instructions and datasets for validation.
• a list of requirements and minimum accuracy levels for models using optical remotely sensed snow parameter data
• a journal special issue like the 2016 special issue in Frontiers in Earth Science – Melt Water Retention Processes in Snow and Firn on Ice Sheets and Glaciers: Observations and Modeling, papers feeding into the IPCC Special Report on Climate change and the oceans and the cryosphere.
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.

Contributions are welcomed in the form of oral presentations and/or posters. Presentation duration will be 15-20 minutes, including discussion. One or more longer invited keynote presentations are planned.
Abstracts and registration
Those intending to attend the workshop should submit abstracts (maximum length 200 words) by email to Peter Langen ([hidden email]) no later than the registration deadline Friday 18 August 2017. Abstracts should indicate whether an oral or poster presentation is preferred.
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.
A range of hotels and hostels exist near the workshop location. Public transit is very efficient, including bike rental. Booking these early is recommended due to high demand that may occur.
Hope to see you in Copenhagen,
Peter Langen (DMI) and Jason Box (GEUS)
