NOAA/NESDIS/STAR has designed, developed, and implemented the GOES-R Algorithm Working Group (AWG) Product Processing System Framework. The framework enabled the development and testing of the Level 2 Advance Baseline Imager (ABI) and the GOES-R Lightning Mapper products within a single system. Fifty six GOES-R ABI algorithms and one GLM algorithm have been run within the framework with product precedence. The task of algorithm integration is highly intensive work, especially when the same tasks are required for each algorithm upgrade. To reduce the algorithm integration time, the framework was redesigned to make it easier to integrate the algorithms. The redesign resulted in the framework becoming more of a plug-and-play system with the scientific algorithms. To enable the plug-and-play capabilities, the algorithms had to be modified such that any data required by the algorithm is brought in via a function call. These modifications enable an algorithm to be developed and/or tested in both the framework and the scientist's offline research system with little to no modification or addition to either system. This approach enables both the algorithm developers and algorithm integrators the ability to work on the same software since the algorithm now can be “dropped” into both systems resulting in simple algorithm rollbacks. Changes to the software in either system can then be easily delivered to the other system and tested. The design details of the Framework redesign and the function call implementation shall be discussed.
