Validation and Drift Analysis for the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) Trace Gas Data Set
Abstract
To progress from monitoring atmospheric composition to investigating and quantifying atmospheric changes, well-characterized measurements over many years are required. The long lifetime of the Atmospheric Chemistry Experiment (ACE) has provided more than a decade of composition measurements that contribute to our understanding of ozone recovery, climate change and pollutant emissions. The primary ACE instrument on SCISAT is a high-resolution (0.02 cm-1) Fourier Transform Spectrometer (ACE-FTS) operating between 750 and 4400 cm-1. The ACE-FTS data set provides profiles of temperature, pressure, and volume mixing ratios of more than 30 atmospheric trace gas species, as well as 20 subsidiary isotopologues of the most abundant trace atmospheric constituents. The profiles from this Canadian scientific satellite mission provide altitude-resolved data that are necessary for understanding processes that occur at specific altitudes or over limited vertical length scales. This paper will describe current validation results for the ACE-FTS version 3.5 data set and describe the drift analyses that are being undertaken to characterize these data to enable the generation of climate data records.
