DESIS instrument can acquire data from nearly 90% of the populated Earth due to the pointing capabilities of the MUSES platform and the DESIS instrument. Two types of data products can be distinguished. The internal L1A products are stored in the long-term archive of the DLR and are accessible for internal use only. The L1B, L1C and L2A products can be generated and delivered to DESIS science users according to their request.
The fully automated processor works on tiled data (1024 x 1024 pixels) covering ~ 900 km2. It runs on users request and considers processing parameters defined by the users.
The DESIS products are described in Table 1 (all products with a * can be delivered to science users via a proposal).
Spectral binning means the summation of adjacent spectral bands (taking into account the spectral response functions). Standard binning is performed in the L1B processor and is denoted as software (SW) Binning.
(Note: Four spectral binnings can be selected with no-binning results in 235 spectral bands at ~2.55 nm spectral resolution (FWHM), 2x binning with 118 spectral bands (~5.10 nm FWHM), 3x binning with 79 spectral bands (~7.65 nm FWHM) and 4x binning with 60 spectral bands (~10.20 nm FWHM)). As the spectral resolution is band-dependent, the given spectral resolutions are average values, and the precise values are provided in the metadata.
