PROBA-1 DOWNLOAD Dataset available after EO SIGN IN registration.

blue arrow DESCRIPTION

CHRIS acquires a set of up to five images of each target during each acquisition sequence, these images are acquired when Proba-1 is pointing at distinct angles with respect to the target.

CHRIS Level 1A products (supplied in HDF data files, version 4.1r3) include five formal CHRIS imaging modes, classified as modes 1 to 5:

Mode Name Swath Spectral Bands Nadir ground sampling distance
MODE 1   Full swath width 62 (773nm / 1036nm) 34m @ 556km
MODE 2 WATER BANDS Full swath width 18 17m @ 556km
MODE 3 LAND CHANNELS Full swath width 18 17m @ 556km
MODE 4 CHLOROPHYL BAND SET Full swath width 18 17m @ 556km
MODE 5 LAND CHANNELS Half swath width 37 17m @ 556km

 

All Proba-1 passes are systematically acquired according to the current acquisition plan, CHRIS data are processed every day to Level 1A and made available to ESA users.

Observation over a new specific area can be performed by submitting the request to add a new site to the acquisition plan.

blue arrow HOW TO ACCESS THIS DATA

Users can freely access the collection using the below links and will be requested to login (new users shall register) to ESA EO Sign In to download the products.

ESA internal users can use their ESAAD account.

The products are available for download via the following interfaces:

ESA EO Multimission Catalogue (EO CAT) Allows users to discover and search products among the available datasets from ESA and Third Party Missions and instruments, using various criteria (spatial, temporal, specific).

ESA Third Party Missions (TPM) dedicated dissemination service and catalogue The data is collection based and allows data browse and download through the treeview as well as via geographical search using a clickable zoom map.

project proposal with 'PROBA/CHRIS request for acquisitions' table in attachment has to be submitted to ask for the addition of a new site to the acquisition plan: the request outcome shall be provided after project proposal evaluation and feasibility analysis.
