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?
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?...
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!
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?)
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
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
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
