MIPAS temperature from the stratosphere to the lower thermosphere: Comparison of vM21 with ACE-FTS, MLS, OSIRIS, SABER, SOFIE and lidar measurements
We present vM21 MIPAS temperatures from the lower stratosphere to the lower thermosphere, which cover all optimized resolution measurements performed by MIPAS in the middle-atmosphere, upper-atmosphere and noctilucent-cloud modes during its lifetime, i.e., from January 2005 to April 2012.

| description | We present vM21 MIPAS temperatures from the lower stratosphere to the lower
thermosphere, which cover all optimized resolution measurements performed by
MIPAS in the middle-atmosphere, upper-atmosphere and noctilucent-cloud modes
during its lifetime, i.e., from January 2005 to April 2012. The main upgrades
with respect to the previous version of MIPAS temperatures (vM11) are the
update of the spectroscopic database, the use of a different climatology of
atomic oxygen and carbon dioxide, and the improvement in important technical
aspects of the retrieval setup (temperature gradient along the line of sight
and offset regularizations, apodization accuracy). Additionally, an updated
version of ESA-calibrated L1b spectra (5.02/5.06) is used. The vM21
temperatures correct the main systematic errors of the previous version
because they provide on average a 1–2 K warmer stratopause and middle
mesosphere, and a 6–10 K colder mesopause (except in high-latitude summers)
and lower thermosphere. These lead to a remarkable improvement in MIPAS
comparisons with ACE-FTS, MLS, OSIRIS, SABER, SOFIE and the two Rayleigh
lidars at Mauna Loa and Table Mountain, which, with a few specific exceptions,
typically exhibit differences smaller than 1 K below 50 km and than 2 K at
50–80 km in spring, autumn and winter at all latitudes, and summer at low to
midlatitudes. Differences in the high-latitude summers are typically smaller
than 1 K below 50 km, smaller than 2 K at 50–65 km and 5 K at
65–80 km. Differences between MIPAS and the other instruments in the
mid-mesosphere are generally negative. MIPAS mesopause is within 4 K of the
other instruments measurements, except in the high-latitude summers, when it
is within 5–10 K, being warmer there than SABER, MLS and OSIRIS and colder
than ACE-FTS and SOFIE. The agreement in the lower thermosphere is typically
better than 5 K, except for high latitudes during spring and summer, when
MIPAS usually exhibits larger vertical gradients. |
