BASCOE assimilates Aura-MLS with a latency of 3 days, delivering analyses of O3, H2O, N2O, HNO3, HCl, ClO, and CO. This NRT implementation has been described and validated by Lefever et al. (ACP, 2015) and keeps operating as part of the CAMS validation service.
This changelog page provides all details about the current NRT implementation. The analyses for the 6 latest months are publicly available on our ftp server (no registration required) in the netCDF format (look here for technical details).
