  1. Product-Generation in ESG:some explorations of the user experienceSteve Hankin – March, 2007

  2. The user’s experience of ESG begins with the sign-on process. This story board picks up after that point … Continue Suppose the user elects to perform a search Search our holdings tofind data of interest? No thanks. I know whichdata I want to work with. Continue The user is offered a choice … ESG Story Poard – product subsystem

  3. User constrains the search ESG will offer a search interface through which the user can discover runs of interest . (This Story Board will not attempt to explore the ESG search experience. RDBMS and OWL/RDF options are being examined in a separate discussion.) ESG Story Poard – product subsystem

  4. Preview Preview reduced-resolution data Continue Obtain or analyze data data Experiment 2 Imagine a metadata summary of this experiment here … Next we’ll run through a scenario for “preview mode” access to the data. Question: Do the benefits of a preview mode justify the added complexity? The info icon leads to human- readable metadata User selects the run-variables of interest The result of a search is a list of “run-variables” (*) (*) A “run-variable” means a variable that is output by a model run. Even if the result of a search is simply a “model run”, that search result implicitly carries along with it a list of the output variables. ESG Story Poard – product subsystem

  5. Experiment 4 ESG Portal – Preview reduced-resolution data Reduced resolution data for preview Experiment 2 – AAA Pre-industrial Naviga-tionbar of some kind … Experiment 4 – H&R winds ESG Story Poard – product subsystem

  6. ESG Portal – Preview reduced-resolution data Reduced resolution data for preview Experiment 2 – AAA Pre-industrial Naviga-tionbar of some kind … Experiment 4 – H&R winds Temperature Salinity (no reduced resolution data available) Zonal velocity (no reduced resolution data available) Meridional velocity (no reduced resolution data available) User selects variable of interest A dimmed variable name indicates that no preview dataset is available ESG Story Poard – product subsystem

  7. ESG Portal – Preview reduced-resolution data ESG Story Poard – product subsystem

  8. Desktop: Matlab, IDL, IDV, Ferret, GrADS, … Rapid Access to Reduced Resolution Information Products • Custom subsets: • netCDF, • binary, • spreadsheet, • GIS layer, … ESG Story Poard – product subsystem

  9. Preview Preview reduced-resolution data Continue Obtain or analyze data data But this time we click on “Continue” Lets return to our search results -- the list of “run-variables”. ESG Story Poard – product subsystem

  10. Zoom User can zoom in on the time region of interest … We enter a tool to help visualize all of the available data selected from the search – both offline and on-line ESG Portal – Select time periods of interest Experiment 2 – AAA Pre-industrial Variables from Experiment 2 Naviga-tionbar of some kind … [+] Experiment 4 – H&R winds Variables from Experiment 4 time resolution [-] Temperature Preview Monthly 3-day 1-day Preview Salinity Monthly On-line 3-day Off-line 1-day Year: 2100 Year: 2000 ESG Story Poard – product subsystem

  11. Zoom ESG Portal – Select time periods of interest Pick the variables and time resolutions he wants … Experiment 2 – AAA Pre-industrial Continue Variables from Experiment 2 Naviga-tionbar of some kind … [+] And continue to his shopping basket Experiment 4 – H&R winds Variables from Experiment 4 time resolution [-] Temperature Preview Monthly 3-day 1-day Preview Salinity Monthly On-line 3-day Off-line 1-day Year: 2070 Year: 2060 ESG Story Poard – product subsystem

  12. ESG Portal – My Shopping Basket My Shopping Basket Or he can continue into the product generation system As we will nowdo … Naviga-tionbar of some kind … Offline data TapeToDisk [+] Experiment 4 Salinity 1-day 2060:2070 He can request migration of data from tape to disk (outside the scope of this Story Board) … FTP raw files Online data [-] Experiment 4 Temperature Preview 2000:2100 Continue Experiment 4 Temperature 3-day 2060:2070 He can FTP the raw files (also outside the scope of this Story Board) … Experiment 4 Temperature 1-day 2060:2070 Experiment 4 Salinity 3-day 2060:2070 Remove fromshopping basket ESG Story Poard – product subsystem

  13. Experiment 2 Experiment 4 – H&R winds ESG Portal – Request visualizations and products All on-line data My Shopping Basket Naviga-tionbar of some kind … ESG Story Poard – product subsystem

  14. Experiment 2 ESG Portal – Request visualizations and products All on-line data My Shopping Basket Naviga-tionbar of some kind … Experiment 4 – H&R winds Preview User selects data of interest Temperature 2000:2100 3-day resolution Temperature 2060:2070 Salinity 2060:2070 1-day resolution Temperature 2060:2070 ESG Story Poard – product subsystem

  15. As before, user can select geometry, region, product and options … ESG Story Poard – product subsystem

  16. Desktop: Matlab, IDL, IDV, Ferret, GrADS, … Continuing with a look at some of the subtler aspects of products … Information Products • Custom subset: • netCDF, • binary, • spreadsheet, • GIS layer, … ESG Story Poard – product subsystem

  17. Analysiscapabilities Operation could be performed server-side or client-side … Define a new variable by applying simple transformations (averaging, variance, extrema, …)

  18. Model Inter-comparison Compare fields When grids differ regridding is automated ESG Story Poard – product subsystem

  19. Ensemble comparison Ensemble comparison is not just a viz style – it is a custom user interface “mode” ESG Story Poard – product subsystem

  20. Demanding (large) products may be created in “batch” mode ESG Story Poard – product subsystem

  21. Another example of server-side analysis On-the-fly regriddingfrom curvilinearto rectilinearcoordinates ESG Story Poard – product subsystem

  22. Through OPeNDAP -- seamlessly segue from the browser to analysis in user’s favorite desktop tool ESG Story Poard – product subsystem

  23. Server-side analysis available at the desktop, too The remote dataset is just an OPeNDAP URL http://server/my_output e.g. Vertical average of variable “TEMP” http://server/_expr_{my_output}{Tave=TEMP[Z=@AVE]} Define a new variable on-the-fly ESG Story Poard – product subsystem

  24. Server-side analysis note: • “Delayed evaluation” • Calculations are on-demand, “surgical” • So, despite the huge size of the data, to the user the whole domain appears to have been transformed ESG Story Poard – product subsystem

  25. e.g. Unix shell script access to products All ESG products (well, nearly) can also be made available through a service interface. In this example we show shell script access. Query available data sets: Query variables in data set “model_1”: Query space-time domain: Request a subset of data as a netCDF file: >lasls http://cpu/LAS >lasls http://cpu/LAS  model_1 >lasls http://cpu/LAS  model_1  sst >lasget  -x 20:60  -y 20:60 -t 11-Dec-2000  -f netcdf        http://cpu/LAS  model_1 sst ESG Story Poard – product subsystem

  26. The service interface also opens the door for special purpose UIsThis shows an example developed for K-12 students ESG Story Poard – product subsystem

  27. Returning, finally, to the starting point…Here is a scenario for the advanced user, who has just signed-on and wants to return to his work from an earlier session. Continue Search our holdings tofind data of interest? No thanks. I know whichdata I want to work with. The returning user clicks here Continue ESG Story Poard – product subsystem
