Combined SAGE II–GOMOS ozone profile data set for 1984–2011 and trend analysis of the vertical distribution of ozone
We have studied data from two satellite occultation instruments in order to generate a high vertical resolution homogeneous ozone time series of 26 yr. The Stratospheric Aerosol and Gas Experiment (SAGE) II solar occultation instrument and the Global Ozone Monitoring by Occultation of Stars (GOMOS) instrument measured ozone profiles in the stratosphere and mesosphere from 1984–2005 and 2002–201...
متن کاملGOMOS: Ozone profile measurements by stellar occultations
The Global Ozone Monitoring by Occultation of Stars instrument (GOMOS) will be launched on board ESA’s Envisat satellite in late 2001. GOMOS will measure ozone and trace gases in the atmosphere by detecting the absorption of star light in UV, visible and infrared wavelengths. GOMOS will deliver ozone and other trace gas profiles at altitudes 15-90 km with a good vertical resolution and with a g...
متن کاملValidation of Gomos Ozone Profiles Using Ndsc Lidar: Statistical Comparisons
The lidars deployed in the NDSC framework have been used for the validation of GOMOS onboard ENVISAT. During the commissioning phase around ten coincidences per site have been investigated. No significant bias, larger than ±5%, has been reported except around 50 km and 20 km where both techniques are known to present some limitations. The estimated errors of both GOMOS and lidar are in good agr...
متن کاملInfluence of Scintillation on Quality of Ozone Monitoring by Gomos
Point-like nature of stars leads to significant disturbances of light beams passed through the atmosphere by refractive effects. These effects should be taken into account in retrievals from stellar occultation measurements. We consider the influence of scintillation on stellar occultation measurements and on quality of ozone retrievals from these measurements, based on experience of the GOMOS ...
متن کاملGOMOS ozone profile validation using ground-based and balloon sonde measurements
The validation of ozone profiles retrieved by satellite instruments through comparison with data from groundbased instruments is important to monitor the evolution of the satellite instrument, to assist algorithm development and to allow multi-mission trend analyses. In this study we compare ozone profiles derived from GOMOS night-time observations with measurements from lidar, microwave radiom...
