2. Background
EP-18.A01 (2017): GRWG to prepare specifications and methodologies for CGMS agency development of operational instrument performance monitoring systems
Based on CGMS WGII Recommendation in 2015: CGMS operators to consider displaying instrument performance in a way similar to the ICVS
NOAA kindly introduced ICVS at 2016 GSICS User’s Workshop
Specification and methodologies: means system configuration and how to generate monitoring information
Actionee is GRWG, but GDWG inputs are needed

5. What is expected for GDWG
To provide guidance/recommendation on the system configuration of ICVS-like system
This fits to GDWG ToR – GDWG shall:
Support the specification of GSICS systems administered by the GCC; GSICS product catalogue, GSICS User Messaging Service, GSICS Wiki, etc.
Support the specification of GSICS systems and tools administered by the GSICS member and observer organizations

6. Services NOAA ICVS provides the following services
Monitors over 400 parameters for 28 instruments onboard NOAA/METOP/SNPP satellites
Monitors and trends the SNPP spacecraft parameters , supporting NASA flight team
Monitors the instrument performance through trending the instrument house-keeping and telemetry parameters
Detects the anomaly events and automatically sends the warning messages to NOAA satellite operators, NASA instrument scientists, and senior program managers
Characterizes the sounder SDR data quality with respect to the numerical weather prediction model (NWP) simulations
Provides NWP users and remote sensing communities on the instrument noises for their real-time applications (e.g. error covariance in data assimilation)
Generates high resolution geostationary/polar-orbiting satellite images
4246 all instrument status and data quality trending figures generated in near real time
Supports Suomi NPP life cycle reprocessing by operating SDR processing packages
Presentation by Ninghai Sun (NOAA) at 2016 GSICS User’s Workshop

7. STAR ICVS IT Infrastructure
To support the daily processing activities of four modules in the previous slide, we build up the IT infrastructure shown in this slide.
Blue: STAR internal SDR calibration servers
Green: Cluster super computer for NWP demonstration and mission lifecycle data reprocessing
Blue (right): Small group of server located in university for research and algorithm testing
STAR Internal servers are directly connected to GRAVITE and CLASS for real time satellite data access. Other connections through internet to NWP centers and international data centers can provide ancillary data for data quality monitoring

8. STAR ICVS Data Processing Flowchart
To realize the real-time monitoring and long term trending of satellite operational status and data product quality functions, the ICVS data processing software packages are designed following this working flowchart.
Emphasize customized data for NASA Flight project for instrument health status analysis and automatic anomaly warning notification capability
All intermediate and lifetime statistic data are updated and saved for future additional analysis

9. STAR ICVS Event Log
Presentation by Ninghai Sun (NOAA) at 2016 GSICS User’s Workshop
Suomi NPP instrument event log is now available in STAR ICVS website provided by Cole Rossiter

10. S-NPP Anomaly Alert
Presentation by Ninghai Sun (NOAA) at 2016 GSICS User’s Workshop

11. Discussion Recommendation on web apps?
HTML5 + JavaScript / PHP / Java Applet, …
Alerting System for external users?
If we recommend to implement it, any thoughts?
The last discussion at GDWG: web meeting in 2012
RSS-based technology (e.g. NASA Datacasting) was introduced to implement such system to GSICS Collaboration Server, but no actual progress
basis? Use of the recent popular communication services (SNS)?
Link to/with other calibration/GSICS related system?
Instrument Event Logging DB / Landing Page
