The GOES-R Algorithm Working Group (AWG) was tasked to develop and test candidate (Level 2) product algorithms in a scalable, pseudo-operational demonstration system, as well as develop validation and verification tools. In conjunction with NOAA/NESDIS/STAR, the Cooperative Institute for Meteorological Satellite Studies (CIMSS) at the University of Wisconsin has helped develop and validate algorithms in the GOES-R Algorithm Working Group (AWG) Product Processing System Framework. Routine validations of the various products as they are integrated, as well as performance characterization of the reference implementations, are important parts of this process. To ensure that the algorithms are correctly integrated into the GOES-R AWG Framework, tools were developed to compare datasets between several applicable product generation systems, allowing for quick comparisons that will identify issues or ensure that the algorithm was successfully integrated correctly. These same tools can and have been used to validate the implementation of the GOES-R AWG algorithms with the GOES-R Ground System as compared to the GOES-R AWG Framework and various AWG teams. Once the algorithm is integrated in to the AWG Framework, a set of routine monitoring tools are used to visualize the products on a routine basis as well as provide statistics over the course of time. These tools can alert when a given image produces unexpected results. The next step is routinely validating the products with truth datasets, such as the CALIOP lidar. Because the truth data is not in the same spatial and temporal step as the native satellite data, tools to collocate these data with satellite data and then validate the algorithms have been developed.

An overview and examples of these routine validation efforts for the GOES-R and enterprise algorithms produced by the AIT Framework from multiple instruments, including simulated GOES-R imagery, VIIRS,Himawari-8 and other instruments as well as example data from the GOES-R Ground System will be shown. In addition the tools used to do these validations will be discussed.
