Comparison of ozone profiles from ground‐based lidar, electrochemical concentration cell balloon sonde, ROCOZ‐A rocket ozonesonde, and Stratospheric Aerosol and Gas Experiment satellite measurements

Abstract

A series of coordinated atmospheric ozone profile measurements was made during October and November 1988. The instruments making observations and their locations were as follows. The Jet Propulsion Laboratory (JPL) and Goddard Space Flight Center differential absorption lidar systems were located at the JPL‐Table Mountain Facility 34.4°N, 117.7°W. The electrochemical concentration cell balloon sondes and the rocket ozonesondes were both launched from Point Mugu Naval Air Station at 34.2°N, 119.2°W. Stratospheric Aerosol and Gas Experiment (SAGE II) satellite measurements were at various latitudes and longitudes but only measurements made within 1000 km of both of the above sites were considered for this intercomparison study. It was found that at least for the time of year of the study, SAGE II measurements agreed only when they were made much closer than 1000 km (<500 km) from the other sites, and this is explained in terms of the large latitudinal gradient observed in the ozone concentration profile. Agreement to 5% was seen between the instruments, over the altitude range from 20 to 50 km, when the measurements were made close together in both time and space.

Stratospheric Chemistry

“…Much of this effort is summarized by WMO [1990]. McDermid et al [1990] summarize the results of an intercomparison in late 1988 of several techniques ‐ DIAL lidars from the Jet Propulsion Lab and Goddard Space Flight Center, ROCOZ‐A rocket ozonesondes, ECC sondes and the SAGE II instrument on the ERBS satellite ‐ and show agreement to within 5% from 20 to 50 km altitude. Good agreement of several remote techniques was also obtained during the Balloon Intercomparison Campaign [ Robbins et al ., 1990].…”

Assessment of the performance of ECC‐ozonesondes under quasi‐flight conditions in the environmental simulation chamber: Insights from the Juelich Ozone Sonde Intercomparison Experiment (JOSIE)

“…The earlier intercomparisons [ Attmannspacher and Dütsch , 1970, 1981; Kerr et al , 1994], included only ozonesondes, without comparisons to a reference profile measured by a separate technique. Other intercomparisons [e.g., Hilsenrath et al , 1986; Aimedieu et al , 1987; McDermid et al , 1990; Komhyr et al , 1995; Beekmann et al , 1994, 1995] used a reference profile measured by other techniques. Results of these intercomparisons yield better estimates of absolute errors for the sonde measurement as a function of altitude.…”

Aerosol lidar intercomparison in the framework of the EARLINET project 1 Instruments: erratum

“…3,4 In the stratosphere, ballonsondes, rocket sondes, and satellite measurements were used for intercomparisons. 5,6 Watervapor lidars, especially true Raman lidars, had frequently been compared to free-flying radiosondes, because the necessary calibration of the systems is similar. 7,8 Water-vapor DIAL systems had also been compared to tethered balloonsondes and other passive remote sensors, with good results.…”
