Resumen:
The DIAL system belonging to Observatorio
Atmosférico de la Patagonia Austral, Río Gallegos, Argentina has been
included in the NDACC since December 2008. One caveat of large networks such
as NDACC is the difficulty to report information of similar nature
consistently from one research group (or instrument) to another. The
inversion algorithm used in the stratospheric ozone DIAL measurements
involves different source of systematic and statistic errors. Due to the
rapid decrease of the signal-to-noise ratio in the high stratosphere, it is
necessary to degrade the vertical resolution of the measurement in order to
limit the statistical error at this altitude range, to reasonable values. The
final statistical error on the measurement is the result of a compromise
between the experimental system characteristics such as the duration of the
measurement and the final vertical resolution. The aim of this study is test
the DIAL algorithm resolution used to retrieve the ozone profile comparing
with the synthetic ozone profile. This synthetic ozone profile is calculated
by mean of lidar equation using an ECC
sonde profile as input parameter. This ozone profile was measured with an
ozonesonde launched in Río Gallegos in March 2011 as part of intercomparison
campaign.
