AB: Popocatépetl volcano 60 km SE of Mexico City is a high-emission rate, passively degassing eruptive stratovolcano. On December 21 1994, Popocatépetl started to erupt and the activity has continued, consisting of degassing, explosions, ash emissions and lava, as well as the recurrent dome formation and destruction by explosions of variable energy magnitude as well as seismicity. Popocatépetl forms part of the Network for Observation of Volcanic and Atmospheric Change (NOVAC). The NOVAC project encompasses a global network of stations to monitor volcanic gas emissions using Scanning Dual-beam miniature - Differential Optical Absorption Spectrometer (Mini-DOAS) instruments. This report describes the installation, at Popocatépetl volcano, of three Scanning Dual-beam DOAS instruments as part of the NOVAC project. Details of the installation, selection of suitable sites and data transfer are further discussed. First results from the instruments are also presented, and particularly the usefulness of this array.
