Transcript Discussions session 2-4 - met.no wikis project index

Session 4: solutions
This session is expected to define solutions to the identified problems through:
• A better cooperative effort within our group:
• publications (including publishing the outcomes of this workshop)
• building projects (collecting in situ measurements, building datasets,
visiting scientist activities)
• Better links with the Arctic community through involvements in National or
international programs.
• There are information to exchange and issues to discuss such as: Would it be
interesting to approach these projects collectively (under the OSI SAF
umbrella?) or not.....

EO-1-2014: New ideas for Earth-relevant space applications
•
New and hitherto immature uses of Earth-relevant space-based data (also taking into account specific satellite sensor acquisition modes)
should be investigated to enable integration or assimilation into scientific investigations related to Earth system sciences, or forecasting models
at regional or wider geographical extent. Attention should be given to space based data covering geographic areas sensitively affecting the
earth system, as is the case for instance for the Arctic and Antarctic regions.
•
EO-2-2014: Climate Change relevant space-based Data reprocessing and
calibration
•
Specific challenge: Research areas such as Climate Change address long time periods of data records, where historical data are essential to
identify reliable trends and anomalies. The data from past remote sensing missions available either from European and non-European missions,
must be made accessible in a way to establish seamless time series of similar observations, contributing to the generation of Climate Data
Records across sensors and technologies over two decades and more. At the same time, the relevance of space derived variables and
products needs to be critically examined, and enhanced to optimally fit the requirements arising from current policy issues in a variety of EU
sectors. This includes the needs of assessment of impact of climate change, as well as mitigation and adaptation strategies in different societal
benefit areas. This work is complementary to efforts undertaken by ESA in the Climate Change Initiative (CCI), and will require coordination with
on-going efforts accordingly.
•
EO-3-2014: Observation capacity mapping in the context of Atmospheric
and Climate change monitoring
•
Scope: To achieve this, research is needed to assess gaps in remote observation availability and suitable approaches for defining virtual
observation constellations. It should include mapping of ground based networks, airborne, balloons and sub-orbital platforms as well as space
based sensors. Appropriate calibration and validation of data is to be assessed, charting the campaigns that will be needed to cover the climate
change monitoring needs in years to come from remote sensing data gathered over land, water and icy surfaces. A mapping of
available/deployed sensor technologies and measurements should be performed as a first step, to identify gaps in available systems and
current knowledge to characterise the atmospheric, measure atmospheric profiles, profiles and different ground level conditions and ensure the
provision of reliable and accurate Climate Data Records for the atmosphere, land surfaces and oceans. This information should also lay the
basis for drawing up the need for dedicated calibration and validation campaigns combining instruments and measurements deployed in ground
based networks, airborne, UAV, balloons, sub-orbital and in-orbit platforms, as relevant for climate change monitoring. Since this activity is
highly reliant on consensus of the users in form of the scientific community involved in subsequent climate change and atmospheric
measurements/modelling, the proposal will have to mobilise such key players across Europe and globally, and will have to include mechanisms
regarding best practices to reach a consensus on the strategies proposed.
