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.
