TODO

  • SNR: where to compute SNR for reflectance?
  • where to store values for SNR and reflectance?
  • neue Instanz von L1B erstellen oder L1B modifizieren?

TOArad2TOAref

Transforms TOA radiance to TOA reflectance

Input

  • L1B data
  • Solar irradiance spectrum

Output

  • TOAreflectance (L1B overwritten data cubes)
  • Log file / Error message?

Memory Budget

  • < 2 MB

Necessary Functions

  • Sun-earth distance (day, month, year)
  • Spectral resampling (spectrum, SRFs, spectral smile)

Process Work Flow

  • Calculate sun-earth distance
  • Spectral resampling of solar spectrum for each image cokumn using valid SRFs and spectral smile.
  • Transformation to TOA reflectance using sun-earth-distance, solar irradiance spectraum and solar zenith angle.

Testing

  • Input L1B:
