Level-2 Retrieval

The Level-2 Retrieval Module is in charge of performing the retrieval of the geophysical parameters that are objective of the mission/instrument. Depending on the mission and on its definition of the products, this module would generate level-2 data or products at higher level of processing, starting from the L1 products and some other auxiliary.

Depending on the particular retrieval algorithm, other inputs might be needed coming from Geometry Module products and auxiliary data, such as maps that furnish additional information about the area on ground to improve the accuracy of the retrieved Level 2 measures.

The following Blocks have been identified:

  • Coregistration Block
  • Retrieval Block


Biblos.COTS This is Biblos COTS package with installation script. Script installs libraries:- kissFFT- boost- netcdf- zlib- hdf5- eigen

Biblos.Commons This is a package common for all the Blocks and Modules. Commons contain helper functions e.g. for reading NetCDF or parsing XML files as well as Blocks and Modules interfaces.

Tool: Tiff to NetCDF converter BIBLOS works with NetCDF format for the images. This is a tool to convert Tiff to NetCDF. It is external to BIBLOS, the user shall convert the image offline. THe package includes an executable, a README file (with instructions) and an example auxiliary file.
