Available Processors

  • S3 OLCI Radiometry
    Performs radiometric corrections on OLCI, like gas-absorption and Rayleigh correction

    Reconstruct the original nadir and forward view images of Sentinel-3 SLSTR (in development) and Envisat AATSR L1B products
  • MERIS Radiometry
    Performs radiometric corrections on MERIS, like calibration, equalisation and smile-effect correction
  • OWT Classification
    Optical water type classification based on atmospherically corrected reflectances
  • FU Classification
    True colour classification with the discrete Forel–Ule scale
  • Pixel Classification (IDEPIX)
    Classification of pixels (cloud, snow, ice, land, water) originating from optical sensors
  • FLH/MCI retrieval
    FLH/MCI Processor calculates the Fluorescence Line Height and the Maximum Chlorophyll Index
  • ARC SST Processor
    Implementation of parts of the ARC/SST-CCI processor
