This presentation will overview the updated capability of GOES-R Analysis Facility for Instrument Impacts on Requirements (GRAFIIR). GRAFIIR is a system facility established to leverage a host of projects including AWG proxy, AWG algorithms, AWG McIDAS visualization, GOES-R Risk Reduction, sensor tradeoff and calibration/validation. GRAFIIR is to support GOES-R analysis of instrument impacts on meeting user and product requirements. GRAFIIR is for connecting the dots, the components that have been built and/or are under development, to provide a flexible frame work to effectively adopt component algorithms toward analyzing the sensor measurements with different elements of sensor characteristics (i.e. noise, navigation, band to band co-registration, diffraction, etc.) and their impact on products. GRAFIIR continues to play a key role in assisting government on addressing instrument specification waivers.
One of the components developed for GRAFIIR is GLANCE, an efficient comparison analysis tool built to assess and evaluate many of the GOES-R data and products (i.e. imagery, clouds, derived products, soundings, winds, etc.) in a consistent and semi-automated way. This tool can be used to help characterize the effects of changes in sensor characteristics on product performance. It can also be used to quickly test proper product algorithm implementation as various product algorithms are transferred from developers to operators. Furthermore, the concept and build details of GLANCE will also be highlighted to demonstrate a truly functional and effective end-to-end system which supports NOAA's GOES-R ABI project.
