Algorithm Implementation and Validation

• Pre-Launch: L1b and L2+ algorithm implementation in the Ground Segment (GS) is verified by comparing data products produced by the GS with expected results provided by instrument vendors (L1b) and the Algorithm Working Group (ABI and GLM L2+)

• Post-Launch: Products are validated following a Calibration/Validation plan– Validate observatory and ground system operability

and performance– Perform provisional validation of L1b and KPP products– Perform beta validation of L2+ products using in-situ

observations and legacy products

Status of Product Generation Sub System Development

• Completed Factory Integration and Test of Product Generation and Distribution software in summer 2014– Successfully demonstrated the capability to generate all

baseline products and distribution to PDA• Successfully demonstrated generation and distribution of

sectorized Cloud and Moisture Imagery (KPP) to AWIPS• Site Integration and Test scheduled in February 2015

– All 3 sites – WCDAS, RBU and NSOF

Summary

• GOES-R Product Generation and Distribution capabilities successfully integrated and tested at factory

• Site integration and test on track• Implementation of science algorithms is being verified by

comparing data products produced by the Ground Segment with outputs generated independently by the instrument vendors (L1b) and AWG (L2+)
