Monitoring of volcanic gases by INVOLCAN/ITER is carried out within the framework of a geochemical program for volcanic monitoring of the Canary Islands. This program involves the operation and maintenance of:

(i) Canary Geochemistry Network, a permanent instrumental network composed of INVOLCAN/ITER geochemical stations.

(ii) Scientific periodic observation campaigns, which are carried out in the various active volcanic systems of the Canary Islands.
