  1. Co-location Satellite, Model, and Ground Data Arif Albayrak GES-DISC NASA

  2. Outline • Introduction • Important Aspects by Examples • Co-location Types • Current Prototype Development • Conclusion

  3. Introduction • Worked on: • AOD bias correction using ML. • Data analysis (ACOS, Aqua/TRMM, OCO-2, GPM) • Precipitation interpolation (TRMM)

  4. Important Aspects • Precision/Resolution

  5. Important Aspects • Precision/Resolution

  6. Important Aspects • Total number of pixels; • Number of valid pixels; • Value of the central pixel; • Mean; • Median; • Mode; • Standard deviation; • Slope of a plane (for a spatial subset) or line (for a temporal subset) fitted to the subset; • Azimuth (direction) of the slope of the plane; and • Multiple Correlation Coefficient (for a spatial subset) or Linear Correlation Coefficient (for a temporal subset) • Statistics for region of interest
