| Zusammenfassung |
| In the frame of the POMODORO French-German project we have compared ozone profiles
retrieved from IASI and MIPAS data. IASI is a nadir-viewing Fourier transform
spectrometer operating aboard the MetOp platform and MIPAS is a limb-observing Fourier
Transform spectrometer operating aboard the ENVISAT satellite. They are both
observing in the thermal infrared region; IASI from 645 to 2760 cm-1, MIPAS
from 685 to 2410 cm-1. MIPAS data and IASI data are complementary because
MIPAS, being a limb sounder, has high altitude resolution, while IASI as a nadir
sounder has high horizontal resolution and can probe the troposphere. We compared
datasets for different time periods of 2007 and 2008 and different regions of the
world. We found reasonable agreement and investigated case studies for which the
comparison between IASI and MIPAS helps to understand the transport and the
exchange between the troposphere and the stratosphere. We also explored which gain
for the tropospheric sounding can be expected by combining IASI and MIPAS. |
