Mini-SAOZ
SAOZ Miniaturized version developed at LATMOS/CNRS
Two sites in France for long-term comparisons with regular SAOZ:
=> Guyancourt since June 2010
=> OHP since September, 2011 => NDACC qualification
Renewal of Roshydromet/Central Aerological Observatory ozone network 10 instruments under deployment in Russia
1 in prep for CMA Beijing

Future plans
Progressive replacement of aging SAOZ by Mini-SAOZ when major failure
First version of SAOZ / Mini-SAOZ operation manual available
Report for Mini-SAOZ NDACC qualification in preparation
Mini-SAOZ deployment in Arosa in Sept-Oct 2015 for long comparisons with Dobson and other instruments
Mini-SAOZ installation in 2016 at 2 new sites (Maïdo in La Reunion & Seychelles)
Participation in Sentinel 5 Precurssor Cal/Val for stratospheric O3 & NO2 columns. Possible participation in CINDI-2 for tropospheric NO2 columns
Continuation of long-term Satellite/SAOZ comparisons for trends
