Laboratory’s rapid tunable daylight differential absorption lidar system for
monitoring ozone throughout the free troposphere is described. The system
components are optimized to provide continuously and rapidly profiles of
ozone, day or night, with a vertical resolution of 1 km and an absolute
accuracy of ±10% to the tropopause under clear sky conditions.
Routine observations of ozone with frequent error assessments are made by
scanning wavelengths between 286 and 292 nm.

Values given are for the 286–291-nm
wavelength pair.
Statistical errors for 2200 shots (110 s
at 20 Hz) and data from Fig. 14. Actual errors will
depend on ozone profile and can be reduced by combining profiles as
shown.
Upward (downward) arrows denote errors
that increase (decrease) with increasing altitude.
Tropopause from 0 GMT Denver sounding
(210 mbar).
Total errors relative to the Bass and
Paur ozone cross sections.
Sum of (1B2 +
