| 08:15 – 08:30 | Welcome | Jan Polcher, Xubin Zeng and Peter van Oevelen | Jan Polcher and Xubin Zeng and Peter van Oevelen gave the welcome to this first in-person / hybrid meeting after the pandemic. Daniel Klocke Mike Bosilovich Maria Piles are remotePiles Tristal Lecuyer joined remotely. |
| 08:30 – 10:00 | GLASS | Kirsten Findell and Anne Verhoef | GLASS is made of about 10 projects (LUMIP and DICE/GABLS are retired), that are clustered in 3 topical areas: Processes: LoCo (Joe Santanello NASA lead) include several field campaigns (GRAINEX, LAFE, LIASE 2021, FESSTVal 2021) good uptake of coupling diagnostics GLAFO (Volker Wulfmeyer, Stuttgart lead of GLA Feedback Observatories) include turbulence & PBL observations (lidar), there are few major EU site (Hohenheim, Lindenberg, Cabauw, Payerne, Chilbolton in Europe). SoilWat (Yijian Zeng Twente & Anne Verhoef UoR, Laure Condon U.Arizona) with focus on pedotransfer and links to soil properties and root distribution. SP-MIP has interesting results. A 3m soil is clearly not enough. GlobTemp ESA can be used. Benchmarking: PLUMBER2 & PALS (modelevaluation.org) and ILAMB (now under PALS for global runs, interesting for CP to participate (ECMWF/GLASS linkSouhail Boussetta). A new paper documenting the site just published Ukkola et al. 2022. Intercomparison: GSWP3 and LSMIP3 are ongoing. There are 4 new initiatives. Irrigation effort (LIAISE and GRAINEX) got a boost in 2021 thanks to the Irrigation workshop. CLASP (Coupling Land Atmosphere Subgrid Parameterisations) focus on PBL & land heterogeneity, using LES. Origin US. SIFMIP (Solar Induced Fluorescence MIP) aiming at Carbon/Water interactions. SIF nicely linked to transpiration. Parazoo et al. 2020 set the scene for Phase-I. Phase-II expanding on diurnal, synoptic, seasonal evaluation which can be interesting for ECMWF (linkAnna Agusti-Panareda). Nick Parazoo (JPL) is coordinating the SIF benchmarking. CC-dET (cross-cut with GHP) measuring & modelling ET, including interception and open water, and irrigation, Patricia Lawston-Parker (ECMWF link Margarita Choulga ) A BAMS 30-year history paper is being prepared (ECMWF link Gianpaolo Balsamo ). |
| 10:30 – 12:00 | GASS | Sandrine Bony and Daniel Klocke | GASS focus on understanding physical processes in the atmosphere. Good communication with WGNE. GASS will also embrace Digital Earth and VHRES process modelling. COORDE on orographic drag has a publication by van Niekerk et al. 2020 LS4P on land temperature predictability has a publication by Xue et al 2021. Diurnal/Sub-diurnal precipitation project ongoing GAP (GEWEX Aerosol Precipitation) plan to review in Monterey UTCC-PROES (Tropospheric Clouds/Convection) Legacy of WCRP grand challenges are fitting well with GASS. Convective organization/aggregation is blooming (4 review paper in recent years). New observation (EURECA, COMBLEX, MOSAIC, FESSTVal campaigns), new models (storm resolving) and potential synergies (CFMIP, WGNE, GDAP). DYAMOND results are shown as multi-model example. The km-scale storm resolving models are a natural aggregator of GEWEX panels work. GEWEX acknowledge that the landscape is changing because of Destination Earth and the new tools connected. New proposed projects include: Mesoscale organisation of convection/trade-wind & cloud feedback; Organisation of deep convection; Air-sea coupling; Arctic cold-air outbreaks; Stable PBL(follow-up of GABLS); Convective momentum transport; Diurnal cycle of precipitation. Orographic precipitation (INARCH link in GHP). Pan-GASS workshop in Monterey & CPCM (Convection-Permitting Climate Modelling) in Buenos Aires. |
| 13:30 – 15:00 | GDAP | Rémy Roca and Tristan L’Ecuyer | The GEWEX Data Analysis Panel 3 Surface network: BSRN (Christian Lanconelli JRC, manage 76 stations, 16 closed, 9 installed, GCOS recognised reference network), 12200+ monthly files, RAMI project RAMI-V with Nadine Gobron) , GPCC (data is gridded but pre-process data can be obtained (without ID)), ISMN (Vienna to Germany GRDC, Wouter Dorigo former coordinator), 3 Assessment Reports: Water vapor (Phase-II started, publication in ACP/AMT/ESSD/HESS special issue) L Picon leading. On Arctic for Water vapour ACLOUD ACP special issue). Precipitation (Joint IPWC/GEWEX precipitation assessment report is published, ERA5 compares more favourably to CERES diabatic heating compared to ERAI, see page 47, Figure 2.1.3 of the assessment report). See also Remy Roca FROGS dataset for precipitation, and Hirohiko Masunaga et al. 2019. Earth imbalances EI GDAP assessment revealed 93% of heat imbalance is over ocean due to OHC Ocean Heat Content. 2 Projects: Integrated Product Project delivered 1999-2014 dataset combining several observationally based datasets. Robin Guillame-Castel & Benoit Meyssignac. The IPP dataset satisfies Energy & Water closure. ISSCP NextGen (led by Andy Heidinger NOAA and B Khan JPL, Martin Stengel DWD CM-SAF) is reviving, with the aim to have an inter calibrated dataset to be used for cloud cover. Proposed new project on Regional Energy&Water consistency over land (link with GLAFO). 2022 GDAP meeting 26-30 September, Bern, Switzerland. |
