Level-1 Processing
The Level-1 Processing Module is responsible for the generation of level-1 products, from level-1a to level-1c. Raw Data is inputted in the module and processed to remove instrument noises, recover the pixel uniformity and perform calibration and geolocation of the acquired profile.
The L0 pre-processing (e.g. decompression of data packages) is not taken into account.
The L1 simulation contains the following Blocks:
- The Geolocation Block calculates the range, latitude, longitude, height of each sample of the profile.
- The Radiometric Corrections Block corrects the DSNU, the detector chain linearity corrections, background subtraction for Straylight and laser energy normalisation.
- The Cross-talk Analysis computes the cross-talk parameters that allow the retrieval of the Mie and Rayleigh scattering profiles.
- The Physical Signal Retrieval Block
- The Calibration Block performs the radiometric, spectral and dark noise calibration based on instrument measures on a calibration target
