Release of CHRIS PROBA-1 toolbox for SNAP

PROBA -1 continues to provide valuable hyperspectral data to the scientific community, and so the tools to handle this data have been incorporated into ESA’s SNAP multi-mission toolbox.

Data - EO Sign In Authentication (Open)

PROBA-1 CHRIS Level 1A

CHRIS acquired a set of up to five images of each target during each acquisition sequence, these images were acquired when PROBA-1 was 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/Ground Resolution Mode 1 Aerosols 13 km 62 at 34 m (773 nm / 1036 nm) Mode 2 Water bands 13 km 18 at 18 m Mode 3 Land channels 13 km 18 at 18 m Mode 4 Chlorophyll band set 13 km 18 at 18 m Mode 5 Land channels 6.5 km 37 at 18 m Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.
