WCRP-synthetisised requirement for IPY snapshot A polar snapshot with main focus on the physical climate system encompassing the total column from the surface through troposphere and stratosphere to mesosphere including oceans, land, all elements of cryosphere, hydrology at the surface, standard meteorology, hydrological cycle, aerosols, and radiatively important constituencies in the atmosphere, having in mind parameters needed for resolving dynamics and fluxes between various domains + legacy !

Aerosols and atmospheric chemistry: IGACO Dynamics and fluxes: Seaflux (GEWEX), GlobIce; fluxes (esp. Polar) are a problem, in principle

How WCRP will likely use the snapshot data in the future? Process studies, MIPs and model validation: SIOMIP, ArcMIP, ICARP modelling projects etc. & etc. ReAnalysis: meteorological -> ocean -> cryosphere -> chemistry -> fluxes, precipitation, climate system Reprocessing, WOAP OSSEs Change assessment, as a benchmark

Slide15: 

Cryosphere   is undergoing dramatic changes, mostly as a consequence of climate change, and provides best indicators for it is one of the most under-sampled elements within the climate system is important (water, climate, transport, etc.) User-requirement product driven Has a ~10 year time frame Goal 1: resources for observations Goal 2: stronger commitment by observing system operators to sustain the observing system Goal 3: better coordination Approved by IGOSP-11, Rome, Italy, 27 May 2004 Team: Jeff Key (Chair) Mark Drinkwater (Vice-Chair) Don Hinsman (link to IGOSP) Ken Jezek and ~ 50 contributors from 14 countries

Ch 3: Terrestrial Snow: 

Ch 3: Terrestrial Snow Intro, status, shortcomings, recommendations: A plan for surface-based snow-observation networks to be developed: national -> international level consistency: observation methods, reporting standards; improved exchange of data Considerably improved metadata for snow observations are needed. The capability of satellite observations to be improved: support of new systems (e.g., E-GPM/CGPM and CloudSat for solid precipitation) support of algorithm development high-frequency (Ku, X-band) SAR a priority for global SWE Priority to algorithms and new sensors for SWE under a wide range of vegetation conditions. Techniques to merge in situ measurements and satellite retrievals: targeted field projects for snow, its albedo and surface temperature in multiple environments, “Super Sites” Integrated multi-sensor data fusion and global analysis systems that blend snow observations from all sources and produce consistent high-resolution analyses of (at a minimum): 1) the extent of snow cover, 2) snow depth, 3) SWE, and 4) snow wetness using improved algorithms for the objective, optimal combination of snow observations from widely disparate sources, also addressing both mass and energy considerations of snow models.

Ch 11: An Integrated and Coordinated System (1) Satellite remote sensing SAR InSAR PM Altimetry Radar Scatterometry VIS to Thermal IR Gravity Ground control Major Gaps (mostly NPOESS) Airborne observations Ground based observations Modelling, Data Assimilation, Reanalysis

Ch 11: An Integrated and Coordinated System (2): 

Ch 11: An Integrated and Coordinated System (2) Data and Information Management: Need to have common means to view data, see gaps, combine / overlay data, process data jointly, etc., etc. GIS: Virtual globes by GeoVirtual, Google Earth, NASA World Wind, ESRI ArcGIS Explorer, Skyline's TerraSuite, and many more… Challenge for IGOS Themes, need for a joint approach (GeoVirtual)

Ch 11: An Integrated and Coordinated System (3) Integrated near-real time products: CEOP-like approach Data Integrating/Archiving Center at the University of Tokyo and JAXA of Japan Model Output Data Archiving Center at the World Data Center for Climate, Max-Planck Institute for Meteorology of Germany In-Situ Data Archiving Center at the University Corporation for Atmospheric Research of USA More stations Some stations Cryo Obs Cryo Models Cryo Products! Joint with IGWCO, built around snow and precip

Ch 11: An Integrated and Coordinated System (4) Related polar observing systems: Southern Ocean CLIVAR, CliC, SCAR, … CASO iAOOS IASC, AOSB, CliC, … CliC, Arctic-HYCOS Arctic-HYDRA

Ch 12: Implementation (1): 

Ch 12: Implementation (1) Many partners (international, regional, national): ~ 30 Cryospheric community of practice Links within IGOS and IGOS Themes: There is no mechanism yet for combining domain–specific requirements for observations and proposing to observing system operators (e.g. satellite agencies) requirements for missions, sensors and their characteristics which would be optimal and acceptable for all Themes Implementation of CryOS as a stand-alone system (a new observing system ??!!) will be nonsensical. Integration of IGOS Themes (with help of GEO?) is needed.

Ch 12: Implementation (2): 

Ch 12: Implementation (2) General recommendation by IGOS-Cryo to IGOS: In-situ and airborne: complementary work of observing stations, platforms, an inventory required (first step – IPY legacy) Space: strengthen inter-agency coordination (one of first steps made by CEOS/GCOS wrt UNFCCC), from virtual to real constellations – GIIPSY, SAR Interoperability, resource sharing: GIS, “virtual globes”, GRID - IPY DIS is heading towards this

Way forward: 

Way forward Open review: deadline 15 January 2007, work is about to start on incorporating comments received Major flaw to resolve ASAP: ice shelves, also missing in the GIIPSY plans! Submission to CEOS and IGOS – March, April 2007 Approval expected at the end of May 2007 Printing: June 2007 Implementation Phases: 1: 2007-2009, IPY, e.g. GIIPSY 2: 2010-2015 3: After 2015
