ACE-FTS Version 3.0 Initial Validation using Correlative Datasets
Abstract
The ACE-FTS is a high resolution (0.02 cm-1) Fourier transform spectrometer which takes measurements over the 750-4400 cm-1 (2.2 to 13.3 µm) spectral region. It is one of two instruments on board the Canadian SCISAT-1 satellite which was launched on the 12 August 2003 and has now been measuring the atmosphere for ~6.5 years. ACE-FTS is a solar occultation instrument which provides profiles of atmospheric temperature, pressure and more than 30 trace gas species over a latitude range of ~85oN to ~85oS. Direct version comparisons have been produced between the new ACT-FTS version 3.0 dataset, which is currently being processed, and the previous well-validated (version 2.2 + updates) dataset. These show the specific changes made in between the two versions of the ACE-FTS data. Correlative datasets from other satellite instruments such as Aura-MLS and HALOE have been compared to both the ACE-FTS version 2.2 and version 3.0 products for various species, such as O3, CH4, N2O, H2O, NO, NO2, HNO3, HCl and HF.
