október 01, 2021
(8:57) Ekaterina Kurzeneva, FMI: Good morning!
(8:59) Meto Shapkalijevski: Good morning
(8:59) Emily Gleeson (Met Éireann): Dia daoibh ar maidin
(9:00) rontu: Huomenta
(9:02) Dow, Gareth: Morning...is the verification session link working ?
(9:04) Balazs Szintai - C-SRNWP: Marion just wrote me that it is working:
(9:04) Balazs Szintai - C-SRNWP: https://bluejeans.com/498663206/5087
(9:14) Emily Gleeson (Met Éireann): Perhaps looking at S2GLC by ESA might be of use too?
(9:16) Jan-Peter Schulz: COSMO not
(9:16) Jan-Peter Schulz: GlobCover2009
(9:18) Jan-Peter Schulz: GLC2000 in the climat version
(9:18) Jürgen Helmert (DWD): In COSMO it is possible to use ESA-CCI for experiments but not currently in operational forecasts
(9:34) Matthias Raschendorfer: @Daniel: What's about the heat-flux associated to water fluxes in the soil and about related changing heat capacity?
(9:36) Ekaterina Kurzeneva, FMI: Question from me
(9:37) Jan-Peter Schulz: Can you improve your original problem of the surface runoff, from which you started this study?
(9:55) John Lavelle: It might be interesting to compare this with the crop type given by Sen4CAP (http://esa-sen4cap.org/). It is avialable as a VM on CREODIAS.
(9:57) Souhail: Hello @Matthias Raschendorfer, do you have a reference for the cnopy treatement you mentioned last time that have a special parametrization for roughness? Thanks
(9:59) Matthias Raschendorfer: Hello Souhail,
(9:59) Souhail: Thanks @Geoffrey, How do you go from corine classes which have a huge number of clusses to a more pure with ECO SG?
(9:59) Ekaterina Kurzeneva, FMI: What about JRC global water dataset?
https://global-surface-water.appspot.com/
(9:59) Souhail: Sorry I might have missed that part?
(10:01) Souhail: Thanks Geoffrey
(10:01) Emily Gleeson (Met Éireann): Geoffrey also found this paper:
(10:01) Emily Gleeson (Met Éireann): https://www.mdpi.com/2072-4292/13/6/1060
(10:01) Souhail: Hello Matthias
(10:06) Matthias Raschendorfer: Hello Souhail, it's a new and ongoing development. A publication has not yet been finalized. Only manuscripts, presentations and model code so far. Sorry
(10:07) Dmitrii Mironov: Patrick, I have a question to Margarita et al. 
(10:07) Souhail: Thanks @Matthias, it would be nice to be in the loop so we might tested in our system as well
(10:10) Samuel Viana: @Matthias I woul like to stay updated on your develompents with your new roughness parameterization, is there any open site where you upload your advances? Thank you
(10:11) Emily Gleeson (Met Éireann): Do you think at some stage that we should hold a cross consortium physiography meeting to discuss lots of things?
(10:11) Ekaterina Kurzeneva, FMI: @Emily: yes, I support this!
(10:19) Balazs Szintai - C-SRNWP: @Emily: agree, that would be uselful
(10:25) Matthias Raschendorfer: @Samuel: Thanks for your interest! Possibly I'm a bit old-fashioned, since I don't have a public web site for that purpose yet. I'm aiming to  show some more progress soon.
(10:29) Emily Gleeson (Met Éireann): Margarita has some lidar data for the UK that maybe we could use for comparison
(10:29) research: LCZ building height criteria are quite losse and allow for error in that range
(10:30) Margarita Choulga: @Emily, yes - data is from EMU LIDAR data https://www.emu-analytics.com/products/datapacks.php
(10:42) Dmitrii Mironov: Patrick, I have a question to Samuel.  
(10:48) Matthias Raschendorfer: I have a question to Samuel
(10:59) Meto Shapkalijevski: It is iterative method and it very quiclky reaches equelibrium; so there are no large additional com.costs  
(11:02) Dmitrii Mironov: Dear Meto, if your have something written, could you send me the text? I am really curious. I code the the flux profile relationships to compute the fluxes over the water surfaces, and the story got rather complicated because z_0 depends on the surface friction velocity in a rather complicated way. The solution appears to be non-trivial, ad I had to make tricks to make the whole thing usable.  I wonder if you have better ideas.
(11:03) Meto Shapkalijevski: I can have a short comment
(11:04) Souhail: Thanks to All!
(11:04) Jan-Peter Schulz: Thanks!
(11:04) Balazs Szintai - C-SRNWP: Closing session starts in this room at 11:30 CEST
(11:09) Meto Shapkalijevski: @Matthias: yes, the coordinate origin is done as usually at the displacement height. The difference here is that the displacement height depents on the canopy hight, its LAI and the stability. So it is updated ech time step. So for each time step the d is carrying the information of the canopy and stability conditions and adjust to these conditions. 
(11:11) Meto Shapkalijevski: the same is done for the roughness length.
Please note that this can be done in the classical MOST as well (e.g. Zelithinkevich et al 2008 I think)
(11:12) Meto Shapkalijevski: so the pure RSL indicates canopy-induced mixing at accouting for that
(11:21) Patrick Samuelsson: Please remeber that the closing session is another BlueJeans meeting room. See you there!
(11:22) Patrick Samuelsson: No, I'm wrong. It is jere :-)
(11:23) Meto Shapkalijevski: @Dmitrii: yas, I have some text written about the steps of the RSL implemntation and will share it with you of course; but I do not think that it will solve the problem with the z0 - u* dependency in your case. In our case u* is not used to calculate the z0 so it is not directly dependent. However we do have compliated iterative calculation of z0 as well. 
I assume you have the u* in the denominator of the z0 computation so for low u* (stable condition) you get very large values for z0, right? 
(11:27) Balazs Szintai - C-SRNWP: Closing session starts in this room at 11:30 CEST
(11:45) SRNWP-EPS Alfons Callado: Well done Chiara !!!  ;-)
(11:48) Dmitrii Mironov: Dear Meto, thanks in advance for the text. The problem with z_0 as function of u* over is not just z_0 depends on u*, but the dependencies have different functional forms in different regimes (like Charnock over rough surfaces, smooth-surface scaling at low winds, fetch dependent Charnock paameter, etc.). If you iteration, it becomes hard to get the code efficient for vector machines, and I am now struggling with this problem. So I am curious what you, guys, do. Thanks again for sharing your experience.
