Abstract

HFC-23 (CHF

_{3}

) retrievals from the Atmospheric Chemistry Experiment Fourier transform spectrometer (ACE-FTS) have been improved. The volume mixing ratio (VMR) values in the recent update (v6) have increased compared to the previous ACE version 5.2 retrievals, and the relative uncertainties have decreased. The HFC-23 VMR time series has been calculated and compared with Advanced Global Atmospheric Gases Experiment (AGAGE) ground-based measurements, and the agreement has been improved in this new version. ACE data show that HFC-23 has increased at a rate of 1.03 ppt/year in recent years spanning 2012–2024.
