Establishing a System for Long-Term Monitoring (LTM) of Quality Metrics for Joint Polar Satellite System (JPSS) Environmental Data Records

The Center for Satellite Applications and Research (STAR) JPSS Environmental Data Records (EDR) Long Term Monitoring (LTM) team was developed to create a centralized location where operational users and product scientists could monitor the performance of the vast collection of JPSS EDR products in near-real time. Phase 1 of this project consisted of providing daily global maps of all JPSS EDR products and was substantially completed in 2016. The EDR LTM team has recently moved into Phase 2; an extended effort to integrate quality metrics and flags for the various products on the EDR LTM website. Phase 2 will provide users with additional routine validation and visualization tools to monitor global means, maxima, percentages of pixels that meet specified criteria, and other relevant parameters. In particular, these additions will be useful for post-launch validation and monitoring of JPSS-1 EDR products.

This report will overview selected Phase 1 products and detail the status and scope of implementing Phase 2 across the entire JPSS product suite, including aspects to provide quantitative monitoring of EDR product quality and algorithms performance. Examples of the various new graphics and interfaces will also be included, such as maps of quality flags and interactive time series plots of specific product quality measures.
