Presentation Transcript

  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 5th 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? 1979-2004) 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
