1 Scientific Topics to be discussed  Re-run of the baseline simulation? What is the “ best ” forcing?  ERA for meteorology  GPCC (wind under catch?) for precipitation  radiation update for spin-up period. “ new Baseline simulation ” with revised Precipitation?  sensitivity runs?, due date? Better parameter dataset?  Strictly controlled baseline simulations for multi- model analysis: root depth, depth of soil layer, …  Soil depth information  another sensitivity experiments?

2 Scientific Topics to be discussed(2)  Confirmation on ALMA How energy and water balances are expected to be satisfied? Error=SWnet+LWnet-Qle-Qh-Qg+Qa-Qf-Qv- delSurfHeat/dt – delColdCont/dt?...

3 Scientific Topics to be discussed(3)  Overall evaluation matrix [COLA, Adam, ICC] Global fluxes, global water(& energy) budget [COLA, ICC] 10-year climatology (annual/monthly/daily?)  [Adam] Cold and warm season analyses  Quantitative analysis of the performance Let the modelers analyze their products  [any] Flux measurement site/campaign datasets  [COLA] Remote sensing, [IIS] River discharge, [FRSGC] Total water storage  [any] Regional focus  GHP !need to prepare validation datasets available!

4 Scientific Topics to be discussed(4)  Linkage with another projects/communities … [Adam, Randy] Link with GLACÉ, [Adam, IIS, UKMO, Andy] BGC models, G-projects, …  Another sensitivity studies: Repeat of baseline but soil properties correspond to coarser (one step up) soil property:  Giving by soil type map or property distribution?  Randy (&Christa) will prepare the property data.  Nudging hydraulic property? Fracture in rocks?  Due date? (Oct.15, 2004  January 2005?)

5 Logistical Topics to be discussed  Following meetings: Special session in the GEWEX 5 th Conference? AMS 2006 at Atlanta?  Publication strategies Overview article Special issue on JGR-Atmosphere?  Data distribution within GSPW2: monthly mean TAR ball: PASS: “ kanpai ” UID: ” gswp2 ”  Data publication for outside of GSWP2  Research Funding

6 GSWP3  Soil wetness project  total terrestrial water storage change project Including ground water (  GRACE mission) acronym:  Target: Longterm (~100 year?  ) simulation?  trend, interannual variation, … Horizontal water transfer (irrigation, …)  Implementation Need enough time for evaluation/review of the forcing data before start the real simulations

7 Dimensions  Longer period? ERA40? (1958-)/ ISCCP starts from 1982/83 Some reanalysis starts from 1979 onward 50 year? 100 year?  Change in land surface condition  is it considered in the reanalysis? Tackle with “pan-evaporation trend” issues  Better quality?  different spatial & temporal resolution?  Isotopes included, Societal application, …  Merge GSWP and LDAS
