Entry ID: MACQ_NO2

[ Get Data ]

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.

MONOCHROMATORS Ancillary Description
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.

Data can also be accessed directly from the NDACC site, via the provided URL.
