Instead of broadly pursuing all science objectives every month as we have been doing in the past, we plan to focus on particular science objectives in campaigns lasting up to 4 months each. These campaigns are not exclusive, it just means that they will get top priority; other observations are still possible during these campaigns.
The specific campaigns planned are: - Focus on surface observation in at least 1 of 2 orbits during eclipse season #23 (Jan-Feb 2013) - SPICAV NO observation campaign in 1 of 2 orbits in Eclipse season #24 (May-June 2012) - SO2 observation campaign (SPICAV nadir, SOIR, and ground-based) in every orbit of eclipse season #25 (Sep-Oct 2013). - South Polar dynamics campaign: VMC & VIRTIS cloud tracking, and VeRa HGA2 *egress* soundings in every orbit from orbit 2680-2760 (Nov - Dec 2013, note date change for this campaign). - SOIR mesospheric sounding campaign in every orbit of eclipse season #26 (Dec 2013 - Feb 2014). This spans inferior conjunction.
In particular, the SO2 observation campaign is a great opportunity for ground-based observation. VEx will obtain vertical profiles of mesospheric SO2 using SOIR as well as dayside nadir observations using SPICAV-UV to map the spatial and temporal distribution of SO2 and UV absorber. This will happen near maximum elongation of Venus from the Sun, permitting ground-based observations including IRTF/TEXES, JCMT, or even HST observations to elucidate the sulphur cycle.
See above documents for dates of specific campaigns.

- SOIR Files:
In order to make it easier for all observers to have access to the observations date & time performed by SOIR on VEX, the SOIR team has built a web tool which allows the user to find past and near-future observations of SOIR corresponding to several search criteria. This tool can be accessed freely with no password needed through our web site at the following address : 
SOIR solar occultation opportunities in the period 1/1/2012-31/12/2012 are described in the following file: File:SOIR MTP76-MTP86.xls

The Venus ground-based image Active Archive (VAA) allows you to upload and retrieve ground-based Venus observations obtained in infrared, visual or ultraviolet light. The aim of this archive is to complement the Venus Express (VEX) spacecraft observations of Venus with worldwide ground-based images to allow for continuous monitoring of the planet.
