M. Yela, O. Puentedura, and M. Navarro (INTA) – Zenith measurements of column NO2, since 1994 with a grating scanning monochromator . Since 2015, two MAXDOAS systems have been operating (one for NO2 and ozone) and the other for BrO and OClO. The scanning system will continue to take measurements until 2020 in order to overlap with those by the MAXDOAS systems. In 2015 joined NDACC. Data from 1994 to 2016 not yet archived.
