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– PLT- “Post launch re-certification of pre-launch

instrument and algorithm performance”

AWIPS Test Results

• AWIPS Sectors are defined in Appendix E of GS F&PS

• Totals for 24 hour data run:

– Sectorized CMI products are sent to AWIPS as a set of tiles to minimize latency

– e.g., Alaska has 6, Puerto Rico has 4 tiles per sector

– Alaska– Hawaii– Puerto Rico

– Full Disk– CONUS– Mesoscale

East SCMI products 205,520 TilesWest SCMI products 230,160 Tiles

Total 435,680 Tiles

GRB User Readiness

• Space Science & Engineering Center (SSEC at U Wisconsin) is developing a software package for processing GRB data with funding from GOES-R

• GRB V0.1 prototype released March 2015– Creates ABI Level 1 and GLM Level 2 datasets– Writes output to NetCDF4 files– Test dataset provided

• Software and documentation available from website: http://cimss.ssec.wisc.edu/csppgeo/– Includes ICD describing planned upstream data interface

• Planning new releases ~every 3 months, eventually support all GOES-R instruments

Summary

• GOES-R Product Generation and Distribution capabilities successfully integrated, tested and deployed at 3 Sites

• Capabilities will be independently exercised and validated by the Government in Data Operations Exercises

• 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+)
