The Venµs science mission is a joint research mission undertaken by CNES and ISA, the Israel Space Agency. It aims to demonstrate the effectiveness of high-resolution multi-temporal observation optimised through Copernicus, the global environmental and security monitoring programme.
Venµs, to be launched in June 2017, will cover once every two days at least 50 sites representative of the main terrestrial and coastal ecosystems in the world. The 20-metre-resolution images will be taken in 12 spectral bands in the visible and near-infrared ranges.

Level 1 : Single date product, Top Of Amosphere (TOA) reflectances, calibrated and geocoded.
Level 2 : Single date product, surface reflectances after cloud masking and atmospheric correction.
Level 3 : Multidate product, synthesis of cloud free pixels from the level 2 products acquired during a small period of time, it will be produced every 15 days.
A light description of Venµs L1 data is given here.
Additional information on solar irradiance and Earth-Sun distance is provided here
Venµs spectral characteristics are detailed here.
Level2 products provide surface reflectances after atmospheric correction, along with masks of clouds and their shadows.
Data is processed by MAJA chain (before called MACCS) for Theia land data center.
