  1. GLASS panel meeting 2008 batch 1 – De Bilt 2008 GLASS panel meeting – De Bilt 2008

  2. Agenda • Panel membership • Status overview • Roadmap • websites • Newsletter • Past and upcoming meetings • GLASS sponsored EGU • WGNE meeting Montreal (Nov 2008) • Scientific conferences • iLEAPS aug 2009 Melbourne • LUCID workshop sep 2008 Paris • iLEAPS SSG (?) • Progress of the GLASS projects • GLACE2 • LoCo • LandFlux • 24/25 September • summary report of the 24 June meeting • PILPS family (Urban, SnowMIP2, RAMI4PILPS, iPILPS, PILPS-Carbon) • LUCID • Developments in the field and the GLASS panel (revisit Roadmap goals): • multiple global data sets becoming available (GLDAS, GSWP2, WATCH, Princeton): is there a need to merge/compare? • PILPS and dedicated land parameterization studies seem to be on the decline, whereas feedback studies (including assessment of role of land surface in various types of feedbacks) are on the rise. Should this be reflected in the GLASS panel membership? • where is data-assimilation heading to? Any needs/developments for systematic comparisons, extension to carbon, or streamflow? Do we need more coverage in GLASS? • hydrological modelling: lots of activities in the field concerning the merge of land parameterization and routing/wetland modelling/groundwater. Again: do we need to have it represented in GLASS? E.g. Lake model intercomparison? • Additional items.. • website • newsletter • other meetings GLASS panel meeting – De Bilt 2008

  3. Land parameterization issues • Subject • why important? • is there data? and metrics? • is there a community? • is there infrastructure for a test experiment? • how can we help • Regional scale fluxes at (sub)diurnal time scales • represent spatial heterogeneity and mutual interactions • PILPS2C/2E, RhoneAgg, ALMIP, GSWP MM, GLDAS, LES? • Many SVAT/NWP/GCM’s around • LIS? PILPS heritage (e.g. GSWP) • Carbon climate feedback • Dynamic phenology, nutrient availability • Ground water • RS retrievals • Various tiles (urban, lake, land ice) • Chemical emissions (CH4, BVOC, aerosol) GLASS panel meeting – De Bilt 2008

  4. Synthesis paper (BAMS) Martin and Bart to draft before end 2008 • Intro • Structure of GLASS • Two questions: • what did we learn? • Do our model parameterizations represent the high-impact processes adequately? • What did we learn from old GLASS exp’s in terms of land parameterization? • compare old model versions to new ones for one or more of the past PILPS • benefits from ALMA, GSWP2-type netCDF forcings, LIS development • What are the outstanding parameterization issues? • Carbon cycle and dynamic/phenological vegetation • (Observing) spatial heterogeneity of fluxes and mutual lateral interactions • Ground water (high resolution) • Even more different tiles (urban, land ice, lakes) • Biogeochemistry (emissions of CO2, CH4, BVOC, aerosol) • emphasis on future experiments (which makes LIS-type infrastructure even more valuable than offline runs) • LDAS in NWP • interactive with atmosphere (feedback) • How to get involved? • What are the possible synergies between (geophyscially/hydrologically) oriented GLASS community, the biophysical iLEAPS community, the cryosphere CLiC people? GLASS panel meeting – De Bilt 2008

  5. The GEWEX Roadmap Objectives • Produce consistent research quality data sets complete with error descriptions of the Earth's energy budget and water cycle and their variability and trends on interannual to decadal time scales, for use in climate system analysis and model development and evaluation. • Enhance the understanding of and quantify how energy and water cycle processes contribute to climate feedbacks • Improve the predictive capability for key water and energy cycle variables and feedbacks through improved parameterizations to better represent hydrometeorological processes, and determine the geographical and seasonal characteristics of their predictability over land areas • Undertake joint activities with operational hydrometeorological services, related ESSP projects like the GWSP, and hydrological research programs to demonstrate the value of GEWEX research, data sets and tools for assessing the consequences of climate predictions and global change for water resources GLASS panel meeting – De Bilt 2008

  6. The GLASS contribution 2007-2008 • 2007: Complete First Global Analysis of the Energy and Water Cycle with Existing Products (All Panels will contribute to this analysis). (GRP, CEOP, GMPP) (to be lead by Rossow?) • 2007: Conduct coupled land cover change experiment Phase 1: LUCID () • 2007: Complete preliminary analysis for the Snow Model Intercomparison Project-SnowMIP-2 (GMPP) (RE to report in Paris) • 2008: Assess the current capabilities of land data assimilation systems at regional and global scales, and their applicability to regional and global forecast systems. (motivate NWP centers to implement LDAS, carry out comparison exp? GLACE2 exploring predictability) • 2008: Complete first offline intercomparison of radiative transfer processes in land surface models (RAMI4PILPS just started) • 2008: Provide an initial review of the success of GMPP in improving parameterization at operational Numerical Weather Prediction (NWP) and climate modeling centers.
