New Lidar for the Network for the Detection of Stratospheric Change - Mauna Loa Observatory : System Description

Abstract

The development of differential absorption lidar (DIAL) systems for long-term measurements of stratospheric ozone and for potential inclusion in the Network for the Detection of Stratospheric Change (NDSC) [Kurylo and Solomon, 1990] began at JPL in 1986. The DIAL system at the JPL Table Mountain Facility (TMF, 34.4° N, -117.7° W) was developed specifically to have the characteristics suitable for long-term measurements as proposed for NDSC. Regular measurements of stratospheric ozone concentration profiles commenced in February 1988, with temperature measurements beginning in January 1990 and aerosol measurements in July 1991. This system has been fully described elsewhere [McDermid et al, 1990]. The new system incorporates some new developments compared to the TMF system and details of the new design are presented.
