Product-Generation in ESG:
some explorations of theuser experience

for the design of ESG

Nov 2007 ESG Story Board v2 – Product Subsystem 2
Embarrassment disclaimer:
Some of the material that follows is review. Some is self-evident.
… but some folks are relatively new in ESG
… and we wanted to present the material in a coherent fashion
Nov 2007 ESG Story Board v2 – Product Subsystem 3
The user’s experience of ESG begins with the
sign-on process.
This story board picks up after the user has
completed that process …
Nov 2007 ESG Story Board v2 – Product Subsystem 4
ESG provides a data discovery process. The details of that are left
for (many) other discussions …
In this story board we will merely assume that data discovery
process exists, and that a user can return to it
by clicking this button:

Note: Since model output variables exist
within a metadata hierarchy …
•Ensemble (21st century climate scenarios)
•Experiment (steady 2001-level CO2 release)
•Output component (atm., ocn, land, …)
•Time resolution (monthly, annual,)
•Variable (wind, temp,…)
… preferably the Picker will help the user to
remain oriented within this hierarchy.

When variables of interest have been located, the
ESG portal will presumably offer a choice of actions,
including:
1.Visualize, compare, analyze• On-line data only
2.Download• On-line and off-line data
This story board concerns itself only
withVisualize, compare, analyze

Note 2: Product generation (e.g. a time series plot) is best based upon “atomic datasets” (aggregations).
Who in ESG will ensure that on-line data are available through aggregations?
The aggregations must also be communicated to LAS. One solution: a notification to LAS of a change in the ESG THREDDS catalog.

Note 3: What about off-line (tape) data? Picker needs to make it clear which data are on-line and which are not.
Are the ESG goals for off-line data clear? Will there be a process to migrate off-line files on-line? If so, file migration should include aggregation and notification sent to LAS.

Note 4: Server-side data reduction is a vital piece of high-end product services.
LAS knows how to work with server-side capabilities added into TDS. ESG needs to plan for consistency in syntax and capabilities of server-side operations if there are multiple OPeNDAP server implementations in use.

Note 5: Server-side data reduction implies potentially large (and slow) calculations.
Need a mechanism for delayed delivery.
And need to be able to limit compute demands on the server.

Compare different ensemble members, time steps, heights.
(Can also compare vertical sections, time series, etc.)
Nov 2007 ESG Story Board v2 – Product Subsystem 20
Or take diff’s between them
Note 6: Taking differences between institutions (ESG nodes) raises issues of authentication, OPeNDAP access, and logging of data accesses.
Also requires server-side regridding if grids differ.
Aside: We’ll want to provide useful climatologies, too.

Note 7: Downloading capabilities will be a foundation of ESG -- outside of product services. Presumably a request to download data made by a user during product browsing should reuse those capabilities. (right?)
Should he be able to download area-averaged data? Regridded data? Differences between fields?
If there are multiple paths to downloading, we need to harmonize them.

Note 9: We should add CDAT and NCL scripts to this list, right?
(CDAT is already a back-end visualizer for LAS. Should we make a plan to add NCL, too?)
