| Zusammenfassung |
| We present a multi-year database of atmospheric fields of the upper troposphere,
stratosphere and lower mesosphere retrieved from satellite measurements adopting
a 2-dimensional tomographic approach.
The full mission of the Michelson Interferometer for Passive
Atmospheric Sounding (MIPAS) instrument, on board the European Space Agency ENVISAT
satellite, is analyzed with the Geofit Multi-Target Retrieval (GMTR) system to obtain the
MIPAS2D database with atmospheric fields of pressure, temperature and volume mixing ratio of
MIPAS main targets H2O, O3, HNO3, CH4, N2O, and
NO2. The database covers both the MIPAS nominal observation mode measured at Full
Resolution (FR) from July 2002 to March 2004 and the nominal observation mode of the new
configuration, measured at Optimized Resolution (OR) and introduced in 2005. Further to the
main targets, minor species N2O5, ClONO2, COF2, CFC-11, and CFC-12
for the FR mission only have been included in MIPAS2D to enhance its applicability in
studies of stratospheric chemistry. The database is continuously updated with the analysis
of the ongoing measurements that are planned to last until the end of 2013 and extended to
other targets. The GMTR
algorithm is operated on a fixed vertical grid coincident with the tangent altitudes of the
FR nominal mode, spanning the altitude range from 6 to 68 km. In the horizontal
domain, FR measurements are retrieved on both the observational grid and an equispaced 5
latitudinal-degrees grid which is made possible by the 2-dimensional retrieval
algorithm. The analysis of MIPAS OR observations is operated on the same altitude-latitude
fixed retrieval grid used for the FR measurements.
This choice provides a database with a homogeneous
altitude and latitude grid, over the whole globe, covering to date about seven years
of measurements.
The equispaced latitude grid provides a new and convenient layout for
the much needed synergetic studies of data from various instrumental and modeling
sources. MIPAS2D is available to the scientific community through the two web sites
http://www.mbf.fci.unibo.it/mipas2d.html, and http://www.isac.cnr.it/~rss/mipas2d.htm |
