The Kiruna Microwave
Radiometer (KIMRA)
Since 2002 the ground-based
Kiruna Microwave
Radiometer
KIMRA
is in operation at the
Swedish Institute of Space Physics (IRF) at Kiruna (67.84°N, 20.41°E, 425 m asl),
Sweden.
KIMRA is a cooperation of IMK and IRF and covers the
frequency range 195-224 GHz including signatures of ozone, N2O,
HNO3, and ClO. Data
analysis of the measured spectra is performed at IMK in Karlsruhe using same the methods as
for the MIRA 2 measurements.
Results:
73 kB
Time series ozone profiles (upper panel), ozone partial columns above 10 km (middle panel),
and the tropospheric transmission over Kiruna between November 28th, 2002, and
April 16th, 2008, as measured by KIMRA. The seasonal variation is clearly discernible.
