ACE-FTS uncertainty budgets for temperature, ozone, and other baseline species

The Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) is a solar occultation limb sounder on the SciSat satellite, which, in 2003, was launched into a high inclination orbit. Measurements of atmospheric pressure, temperature, and concentrations of over 40 trace species began in February of 2004 and are currently still being made over 17 years later. This study will describe the methodology of producing ACE-FTS uncertainty budgets that are compliant with the recommendations from the TUNER (Towards Unified Error Reporting) SPARC activity. The uncertainty budgets include spectroscopic uncertainties, uncertainties due to field-of-view and instrument line shape modelling, measurement noise, initial climatology uncertainties, and other forward model component errors. Uncertainty budgets for ACE-FTS temperatures and the baseline species, including O3, H2O, NO2, CH4, N2O, HNO3, etc., will be shown and discussed.
