PROBA-1 CHRIS

PROBA CHRIS Level 1A (PROBA.CHRIS.1A)


CHRIS stands for Compact High Resolution Imaging Spectrometer. It was launched aboard ESA's Proba-1 satellite on 22 October 2001 and provides hyperspectral images to a resolution of 18m. The Proba-1 mission objectives are primarily for in-orbit demonstration and evaluation of new technologies, the CHRIS instrument is one of these technologies, the data provided from CHRIS is targeted to help with environmental monitoring applications.

CHRIS data is supplied in HDF data files (version 4.1r3).

CHRIS acquires a set of up to five images of each target during each acquisition sequence, these images are acquired when Proba is pointing at distinct angles with respect to the target.

CHRIS Level 1A products include five formal CHRIS imaging modes, classified as modes 1 to 5:

  • MODE 1: Full swath width, 62 spectral bands, 773nm / 1036nm, nadir ground sampling distance 34m @ 556km
  • MODE 2 WATER BANDS: Full swath width, 18 spectral bands, nadir ground sampling distance 17m @ 556km
  • MODE 3 LAND CHANNELS: Full swath width, 18 spectral bands, nadir ground sampling distance 17m @ 556km
  • MODE 4 CHLOROPHYL BAND SET: Full swath width, 18 spectral bands, nadir ground sampling distance 17m @ 556km
  • MODE 5 LAND CHANNELS: Half swath width, 37 spectral bands, nadir ground sampling distance 17m @ 556km
