Summary
Abstract:
Slant column densities of stratospheric nitrogen dioxide (NO2) determined from spectroscopic measurements of zenith scattered twilight at wavelengths from 430-485 nanometres. These data are provided by the NDACC (Network for the Detection of Atmospheric Composition Change) on an annual basis and then stored at the AADC. Only data that are two years old are made available. Further information ... about the dataset is available from the URL given below.
This work is performed as part of ASAC project 2244.
The fields in this dataset are:
NO2 slant column density (molecules/cm**2)
Error in NO2 slant column density (molecules/cm**2)
NO2 Air Mass Factor (AMF)
NO2 vertical column density (molecules/cm**2)

Public summary of the season progress:
Ground-based measurements of nitrogen dioxide (NO2), one of the key trace gases in the atmosphere, have been made at Macquarie Island since 1996 and span now more than 12 years. These long-term observations made at Macquarie Island help us to bridge the gap between measurements made in the Antarctic and at mid-latitudes. The observations during the 2008/2009 season went smoothly and we have no problems to report.

Quality
Experiment set up in 1996 to replace discontinued dataset at Campbell Island. Data are transferred from Macquarie Island on a monthly basis and initial quality checks made then but full processing is done more typically on an annual time scale.
Access Constraints
Binary data files with spectral measurements, instrument parameters and fitted atmospheric parameters. The raw data are stored to allow for reprocessing as analysis methods improve. Processed data consisted of formatted ascii files giving slant column amounts of atmospheric nitrogen dioxide and ozone.
Data are available for download from the AADC at the provided URL. 2010 and 2011 data have also been archived, but are not yet publicly available.
