CLAES's PLOTS

CLAES AER790_46
(aerosol extinction coefficient)

CLAES aerosol extinction coefficient measurement at 46.4 mbar over length of CLAES observing period.

CLAES ClONO2

Measurement of ClONO2 at 46.4 mbar over length of CLAES observing period. 

Correlation scatter diagrams of CLAES CF2Cl2 and N2O zonal-mean mixing ratios over the altitude range of 19-48 km for various latitudes...

The figure shows global polar projections of CLAES stratospheric CF2Cl2 in ppbv at 21 km (46 mb) in the fall for the northern hemisphere on September 25, 1992 (top panel) and for the southern hemisphere on March 27, 1992 (lower panel). The CF2Cl2 variations in latitude and longitude can be seen in the two panels. [For more information see "Global CF2Cl2 measurements by UARS cryogenic limb array etalon spectrometer: Validation by correlative data and a model," by Nightingale et al.,

Polar orthographic projections of 24 hours of ClONO2 data at 21 km as measured by CLAES in the Arctic stratosphere for individual days between July 1992 and May 1993. These days emphasize the northern winter vortex region and the band or collar of increased ClONO2 around it. [Similar to figures and discussion in "Observations of Lower-Stratospheric ClONO2, HNO3, and Aerosol by the UARS CLAES Experiment between January 1992 and April 1993", by Roche et al., J. Atmos. Sci., 51, 2877-2902, Oct. 15, 1994.] 

CLAES global stratospheric CF2Cl2 is shown as combined, pole-to-pole zonal-mean plots in ppbv for two days in March (top panel) and two days in September 1992 (lower panel). The two days in each case span the CLAES door closure for the UARS yaw around manuever. The double peaked structure at higher altitudes in the tropics in March is probably caused by the semi-annual oscillation (SAO) of the equatorial zonal-mean wind acting on the long-lived tracer gases in the stratosphere.
