- 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 1/1/2012-31/12/2012are described in the following file: File:SOIR MTP76-MTP86.xls.
For further details, contact the SOIR Principal Investigator: Ann-Carine Vandaele <A-C.Vandaele@aeronomie.be>
- VeRa Files:
This file descibes all VeRa radio occultations carried out in the period 1/7/2006 - 2/6/2010.
For further information contact the VeRa team: Martin Paetzold <Martin.Paetzold@uni-koeln.de>, Bernd Hauesler <Bernd.Haeusler@unibw.de>, and Silvia Tellmann <tellmann@geo.uni-koeln.de>
This file describes all opportunities for Radio occultations in occultation seasons in January 2011 - November 2012. File kindly provided by Stefan Remus, ESAC. Note that not all radio occultation opportunities are exploited.

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.
