* Science planning poster: [[File:VEX-SCIOPS-PO-017_1_5_VEX_4th_P1_2013_Overview_2012Sep11.pdf]]
 
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 :
[http://venus.aeronomie.be/en/soir/soir_database.htm]
 
SOIR solar occultation opportunities in the period 1/1/2012-31/12/2012 are described in the following file:

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.

2013

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 : [1]

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 Exploration Analysis Group, established in 2005, is NASA's community-based forum designed to provide scientific input and technology development plans for planning and prioritizing the exploration of Venus over the next several decades

(Between 23 May and 9 June 2007 - ESA web site)

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.
