- Abstract
- The MARSCHALS (Millimetre-wave Airborne
Receiver for Spectroscopic CHaracterisation of Atmospheric
Limb-Sounding) project has the general objectives of demonstrating
the measurement capabilities of a limb viewing instrument
working in the millimetre and sub-millimetre spectral
regions (from 294 to 349 GHz) for the study of the Upper
Troposphere - Lower Stratosphere (UTLS). MARSCHALS
has flown on board the M-55 stratospheric aircraft (Geophysica)
in two measurements campaigns. Here we report
the results of the analysis of MARSCHALS measurements
during the SCOUT-O3 campaign held in Darwin (Australia)
in December 2005 obtained with MARC (Millimetrewave
Atmospheric-Retrieval Code). MARSCHALS measured
vertical distributions of temperature, water vapour,
ozone and nitric acid in the altitude range from 10 to 20 km
in presence of clouds that obscure measurements in the middle
infrared spectroscopic region. The minimum altitude at
which the retrieval has been possible is determined by the
high water concentration typical of the tropical region rather
than the extensive cloud coverage experienced during the
flight. Water has been measured from 10 km to flight altitude
(?18 km) with a 10% accuracy, ozone from 14 km to flight
altitude with accuracy ranging from 10% to 60%, while the
retrieval of nitric acid has been possible with an accuracy
not better than 40% only from 16 km to flight altitude due to
the low signal to noise ratio of its emission in the analysed
spectral region. The results have been validated using measurement
made in a less cloudy region by MIPAS-STR, an
infrared limb-viewing instrument on board the M-55, during
the same flight. (literal)
