Context
Why have a workshop now?
•
Cryosat-2 mission extension until 2017 requested (decision expected at
September 2014 PB-EO)
•
Sentinel-1 satellite launched in April 2014 - first in the series of operational
Sentinel satellites, changing the EO landscape
•
After 8 years of intensive study, CoReH2O EE7 candidate mission was not
selected in March 2013 -> most related scientific studies and campaigns
have now come to an end
•
Living Planet Challenges of the Cryosphere have recently been updated by
the Earth Science Advisory Committee and a new Living Planet science
strategy is in preparation
•
A series of related conferences/workshops over past 12 months (Grain size
workshop, MicroSnow, NASA snow workshop …)
•
Potential new opportunities for mission proposals in 2015, e.g. ESA Earth
Explorer 9 call (?), Venture Class/Decadal survey at NASA (?)
Workshop objectives
•
To review and discuss the major observational gaps in cryosphere
science for the coming decades with a focus on snow
•
To discuss results and progress in observing snow parameters
based on ground, airborne and satellite observations and techniques
•
To discuss the opportunities and challenges offered by the new
generation of EO satellites (e.g. Sentinels) for cryosphere science
•
To consolidate a scientific roadmap outlining the main priorities and
challenges for the cryosphere community in terms of novel
observations, technologies, retrieval methods and novel mission
concepts
Workshop structure
Session 1
•
What has been accomplished and where do we currently stand?
Session 2 & 3 & 4
•
How do we currently observe relevant parameters of the Cryosphere at relevant
spatial and temporal scales?
Session 5
•
What is the instrumentation that we currently use and what could/should be used
in the future?
Session 6 & 7
•
How do we model, assimilate and use the observations?
Session 8
•
How do we validate what we have obtained?
Workshop outcome
•
Scientific roadmap based on inputs from the talks and
discussions at the workshop
•
This roadmap and session summaries will be compiled by the
Session Chairs, Scientific Committee and ESA after the meeting
and will be placed on the workshop website
•
It will be used as input for future studies and activity
development

5 LP Challenges of the Cryosphere
Improve understanding and quantification of:
Challenge C1
Challenge C2
Challenge C3
Challenge C4
Challenge C5
regional and seasonal distribution of sea-ice mass and the
coupling between sea ice, climate, marine ecosystems, and
biogeochemical cycling in the ocean
mass balance of grounded ice sheets, ice caps and glaciers,
partition their relative contributions to global sea-level change;
assess their current stability and sensitivity to climate change
seasonal snow, lake/river ice and land ice, assess their effect to
changes in climate system, water resources, energy and carbon
cycles; improve the representation of the terrestrial cryosphere
in land surface, atmosphere and climate models
influence of ice shelves, ice sheet melt, sea ice formation and
river run-off on thermohaline circulation, ocean stratification,
marine productivity, and determine the response of the global
oceanic and atmospheric circulation
current changes taking place in permafrost and frozen-ground
regimes, understand their feedback to climate system (e.g. CO2
and CH4 balances)
