Test to Test Comparisons

Sensitivity to Algorithm Change

  • ST00 vs ST01 Effect of gain precision
  • ST00 vs ST02 Effect of double-exponential cal table
  • ST02 vs ST03 Effect of revised Earth-Sun distance correction
  • ST00 vs ST04 Effect of Gothic-R
  • ST04 vs ST05 Effect of f/Q
  • ST00 vs ST05 Effect of f/Q + Gothic-R
  • ST01 vs ST03 Effect of double-exponential cal table + gain precision + Earth-Sun
  • ST03 vs ST06 Effect of new vicarious cal
  • ST00 vs ST06 Effect of new vicarious cal + new cal table
  • ST09 vs ST08 Effect of new pressure corrections
  • ST10 vs ST09 Effect of downwelling BRDF correction
  • ST11 vs ST10 Effect of f/Q correction
  • ST12 vs ST09 Effect of glint-subtracted cloud mask
  • ST13 vs ST12 Effect of downwelling, wind-dependent BRDF correction
  • ST14 vs ST13 Effect of f/Q correction
  • ST15 vs ST14 Effect of updated lunar cal & switch to Thuillier

    • Annual and Mission Trends and Images

  • ST00: Operational with higher-precision vicarious gains
  • ST01: Operational
  • ST02: Add new cal table
  • ST03: Add new earth-sun distance correction
  • ST04: Operational + Gothic-R BRDF
  • ST05: Operational + f/Q*Gothic-R BRDF
  • ST06: ST03 + new vicarious cal, new MSl12
