Space helps monitor Earth’s changing biosphere
Earth’s biosphere is continually changing. Through its pioneering Earth observation missions, ESA is making critical contributions to monitor these changes and their impacts on Earth’s water and carbon cycles.

Data - Data Description
Proba-1 CHRIS Level 1A
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 Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.

PROBA-1
PROBA-1 is a technology demonstration satellite that later became an operational Earth observation mission.
Campaign
SPARC
ESA's SPectra bARrax Campaign (SPARC) activity was part of the preparatory study for a proposed ESA Earth Explorer mission called SPECTRA. The objective was to collect a CHRIS/PROBA reference dataset for SPECTRA-related studies.
