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.

New cross-calibration readies PROBA-1 data for climate research

While PROBA-1 has already exceeded expectations by suppling over 21 years of Earth observation hyperspectral data, recent cross-calibration activities are aiming to ensure the data will robustly serve long time-series research, even when the satellite ends operations.
