This manuscript introduces the OZORAM ground-based millimeter wave
radiometer. The instrument is deployed to the high Arctic
(79° N, 12° E) for measurements of O3 in the
upper stratosphere and lower mesosphere.
The publication describes the status of OZORAM in the end of
2010. OZORAM is able to provide profile information between 30
and 70 km altitude in time intervals of 1 h.
To establish applications of the data and to investigate
instrumental biases, the results from September 2008 till summer
2010 are compared to O3 profiles derived from measurements of two
instruments onboard polar orbiting satellites, MLS onboard EOS-AURA
and SABER onboard TIMED. The agreement is within 10% in the middle
and upper stratosphere and 30% in the lower mesosphere. The
deviation shows systematic and oscillating features which are,
however, constant during the period of comparison.
The data set is therefore suitable for studies of mesospheric and
stratospheric response to changes in dynamics or due to solar
influences on climate. |
