TES and OMI Total Column Ozone Comparisons

TES and OMI Total Column Ozone Comparisons

• TES/OMI Collocation Use only the daytime orbit
  measurements from TES
• All four quality flags for TES must pass (two
  flags for radiance residual, one for surface
  temperature, one for effective optical depth)
• Use OMI L3 gridded Total Ozone and Reflectivity
• Make statistical comparisons only for
  measurements lying between 60S and 60N

Summary

• Total ozone from TES and OMI without any cloud
  filtering agree to within about 6 DU (OMI always
  less than TES)
• Total ozone from TES and OMI under near clear-sky
  conditions agree to within about 3 DU, but now
  OMI is larger than TES on average
• For near clear-sky conditions the distributions
  of total ozone from TES and OMI lie close to the
  11 line
