2017 Advanced Climate Dynamics Course (ACDC) @ Bonne Bay Research Station on Newfoundland

Tickets

Sep 11 – Sep 22 all-day

ACDC 2017

Topic: The Dynamics of the Seasonal Cycle

Date: September 11th – 22nd, 2017

Location: Rondvassbu, Rondane National Park, Norway

Application deadline: 10th of March, 2017

Online application form: HERE

Target: Advanced PhD candidates and early career scientists.

Goal: To mix students and lecturers with empirical and dynamical training within
climate science and focus on understanding the basic principles and dynamics of the
seasonal cycle across different timescales. This summer we will explore what we can
learn from the largest reoccurring change in Earth´s climate.

Confirmed lecturers: Peter Huybers (Harvard), David Battisti (University of
Washington), Camille Li (UiB), Jake Gebbie (WHOI), Patrick Heimbach (UTexas/MIT),
Kerim H. Nisancioglu (UiB/UiO), Øyvind Paasche (UiB), Tore Furevik (UiB).

Workshop Modeling Meltwater in Snow and Firn: Processes, Validation, Intercomparison and Model uses of Optical Remotely Sensed Data @ Geological Survey of Denmark and Greenland (GEUS)

Tickets

Sep 20 @ 12:00 – Sep 22 @ 12:00

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.

Purpose

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.

Sessions

Snow model development
Meltwater retention model validation
Meltwater retention model intercomparison project (RetMIP)
Optical remote sensing to improve snow models

Session 1 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.

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:

survey and prioritize remotely sensed snow parameter data users’ requirements for global and regional snow information
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
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.

Financial Support

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.

Venue

Geological Survey of Denmark and Greenland (GEUS), Østervoldgade 10, DK-1350 Copenhagen K

Contributions

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 (pla@dmi.dk) no later than the registration deadline Friday 18 August 2017. Abstracts should indicate whether an oral or poster presentation is preferred.

Financial support

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.

Accommodation

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)

ICAT PhD school 2017 @ University of Copenhagen

Tickets

Sep 25 – Sep 30 all-day

ICAT PhD school 2017

Week 39 -2017

Scope and participation:

The PhD course is aimed at PhD students and junior postdocs who conduct ice core analysis or are users of ice core data (glaciological, oceanographic, climate modelers).

The results from ice cores cannot be fully appreciated without understanding the analytical techniques behind the measurements as well as the implicit assumptions related to the emission, transport and deposition of the species analysed.

These include a variety of approaches such as continuous flow analysis (CFA) for the analysis of impurities, but also ion chromatography, ICP-MS and a number of other methods used for high resolution measurements of the impurity content in ice cores. Laser spectroscopy has replaced older-generation technology such as mass spectrometry for the analysis of some gases preserved in polar ice.

ICAT aims to educate a new generation of ice core researchers and foster a collaborative environment for future glaciological projects.

The course will enhance the knowledge between PhD’s within the ice core community on new methods developed for the analysis of ice core climate.

Application will open shortly and the application deadline is 1st of June.
