Intercomparison of Ozone Profiles

FTIR Kiruna (& Izana):

7 (2) comparisons

with MIPAS version 4.53 (before Nov. 13)

around 20 km: MIPAS vmr too low (up to 0.8 ppmv)

around 30 km: MIPAS vmr too large (up to 0.8 ppmv)

MIPAS columns (integr. prof. >16 km): ~ 10% too large

altitude assignment:

alt. shift of ~1.5 km

MIPAS VMR (p) agrees better than VMR (H)

Conclusion

Comparisons with MIPAS 4.53 (data from Oct. 24 onwards)

using g.b. MWR, LIDAR, FTIR, and O3 sondes

before Nov. 13:

D altitude: 1 - 2 km

< 20 km: MIPAS vmr too low >25 km: MIPAS vmr too large

after Nov. 13:

O3 sondes Uccle & MWR Payerne (110 comparisons !) :

height assignment is reasonable

much better agreement

Quality of MIPAS O3 profiles is quite promising


Envisat validation workshop atmospheric chemistry validation team

Outlook

  • A quantitative validation has to be perfomed

  • Data from MIPAS observations before Oct. 24 are needed

  • More than 1000 files with O3 profile data on CAL/VAL data base

  • Topics to be addressed:

  • day / night differences

  • latitudinal dependence

  • coincidence criteria: influence of different time and geolocation

  • other MIPAS products (species)
