I am pleased to inform you of the EGU Splinter Meeting: Firn Model Inter-Comparison Project.
Monday April 8 17:30–19:00 Room SPM1
Please find a further description of the project below and contact me with questions. This is a public event.
Best regards, Jessica
At University of Washington we are developing a modular
community firn-evolution model funded by the ICEICS PIRE grant at Oregon State
(http://iceics.science.oregonstate.edu/). Because we want to incorporate the best ideas and physical
descriptions of firn from existing models, we are organizing a firn-densification
model inter-comparison project.
glaciological research questions involve physical processes in firn; however,
we are focusing on cold firn for this project, which is targeted at understanding
firn gas (See link above). We will compare new and existing firn-densification models
with a standard suite of boundary conditions, including temperature and
developers are asked to run their model and provide output to be included in the
suite of results.Model-comparison
tests will incorporate synthetic and observation-based boundary conditions. We hope that a community
model-comparison paper will result from all the contributions.
Why: We wish to
compare the response behavior of current firn models to pertinent
questions.For example, what is
the variance among current models in response to temperature
perturbations?In response to
well can different models are replicate observations?Our goal is to determine the most-pertinent physics for a
transient firn model under a wide rage of climate conditions.This will guide future improvements in
When: We hope to
initiate the first simple inter-comparisons on January 18.We will provide a set of boundary
conditions for this initial stage of the project.Further goals, tests, and target dates will be established as the group develops.
Who: All are
welcome to contribute results and modeling expertise. We look forward to working with
