2. Meeting Outline Introduction Background information
Overview of the current situation
What data to offer for plotting and their plot options
Design Options
Discussion
Conclusion

3. Introduction
The purpose of this meeting is to resolve any outstanding issues and have GPRCs agree on a common approach for the bias monitoring web page

4. Background Information
Bias monitoring web page design already discussed at the web meeting and the 2011 Joint Working Groups meeting in Daejeon, Korea
Hiromi Owada (JMA) proposed a template with accompanying prototype files

5. Current Situation
Four GPRCs have so far implemented bias monitoring web pages: CMA, EUMETSAT, JMA, and NOAA.
These pages are hosted on GPRCs websites and use custom-developed software.
All the plots are generated in advance and a user can only selected from those available.
Any GPRC has issues with the current set-up?

6. What Data To Plot & Plot Options

7. Design options

8. Option #1: Leave It As-Is
Pro:
Minimal new effort required.
GPRCs already have the skills and resources to maintain.
Con:
Each GPRC’s bias monitoring page has different user interface.
Implementing any common change depends on particular GPRC.

9. Option #2: One System at Each GPRC
Pro:
More similar web pages at each GPRC.
New features or fixes can be implemented much faster.
Dynamically generated plots.
No need to pre-generate large number of plots.
Con:
All GPRCs must provide plotting data in the same format.
Each GPRC’s IT issues may complicate implementation.
Who is going to develop the software?

10. Option #3: One System at One Site
Pro:
Only one place for every GPRCs bias monitoring.
New features or fixes need to be implemented at one site only.
Unified user interface.
Dynamically generated plots.
Con:
All GPRCs must provide plotting data in the same format.
The data must be publicly accessible.
Who is going to develop the software?
