GOES USERS’ CONFERENCE IV: Discussion Highlights Algorithm Development David Kitzmiller

1. GOES USERS’ CONFERENCE IV:Discussion HighlightsAlgorithm Development David Kitzmiller

2. A) add users and international partners to appropriate AWGs. B) potential new AWGs are decision support and visualization (A) What groups (beyond the system prime contractor and NOAA/NESDIS/ORA) should be represented on the AWG teams? (B) Should there be other potential AWG teams?

3. Definition: Day 1 is the first day of full operations after the intensive on-orbit calibration and checkout period. Lack of input early on from nontraditional users so that the products do not meet their needs for sampling, format, interface, compatibility with their data systems, etc. Do outreach to nontraditional users Data not of advertised quality Data not certified by other agencies (e. g. FAA) therefore cannot be used for their requirements. Recommend NOAA mitigate these risks early 2) What do each of you perceive as the greatest risks for complete data usage on “Day 1” in the area of algorithm development?

4. Test bed to be defined by the algorithm working groups and users to meet their requirements for algorithm development. Post launch validation to be conducted by the AWGs. Algorithm validation plan developed and discussed with the users before launch Include intensive validation experiments and long-term validation for the life of the system 3) What type of test beds and documentation is recommended to demonstrate GOES-R algorithms meet mission requirements? And how should radiances and products be validated after GOES-R is launched?

5. AWG produces the Test Bed Engage the user group in the design and data used in the test bed Provide at least one season of proxy data in the test bed. Include all data types the user community uses Deliver test bed to users at least 2 years before launch Use open standards and platforms for the test bed and data systems. Provide data from on-orbit checkout (operate for 3-6 months prior to on-orbit storage?) to the users through the test bed. 4) What test beds are recommended to allow users to prepare for the utilization of GOES-R products & how far in advance?

6. Test Beds 2 yrs before launch Add a user readiness team to the AWGs User forums Comprehensive performance analysis over full range of conditions Provide real data from the checkout period prior to on- orbit storage to the users through the test beds. 4-6) What do users need when? (Top 4 points):

7. AWG responsible for validation of products and implementing improvements as necessary Evaluate impact on users. User needs is a guide for deciding to implement improvements. Satellite Product Services Review Board (SPSRB) is the mechanism in place at NOAA for this process 7) How should improvements to the algorithms be implemented?

8. Recommend that algorithms source code and documentation to be widely available Should be available to the international community. Important for international collaboration (GEOSS) 8) Will the algorithms and/or software be available to the user communities?  What about the international communities?

9. Test beds will require funding at the receiving agencies to use them and prepare to use the data. Involve the users throughout in the process of algorithm develop, testing, validation and improvement 9) What other questions or issues would you like to have the group discuss?

10. GOALS To optimize the development process To provide efficient transition from the algorithm developers to operations To engage the users Definition An algorithm is an equation that converts data to a desired product. It starts with a piece of code (scientific algorithm) that then needs be documented and placed in robust code and validated with test data including identifying the error characteristics.
