    Satellite data central to ocean monitoring

    Over 95% of Earth’s water is found in our oceans, and yet sadly, oceans are under stress from climate change and pollution. Monitoring our oceans is vital for Earth’s survival and satellites are the primary means of long-term and independent observation of our vast ocean bodies and their associated coastal zones.

    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.
