NOTE: The Level-1 SYN product (SY_1_MISR) is an internal product, and not disseminated to Users.
The SY_1_MISR product is produced by the Synergy software (Level-1 + Level-2 + VGT-P processing) and correspondence grids between all OLCI and SLSTR channels.
Depending on the computed channels and stripes, this product contains 26 to 36 datasets. These datasets are Annotation Data Files (ADFs), that contain the correspondence/collocation grids between OLCI/SLSTR L1b grids and SYN Level 2 reference grid:
The misregistration/collocation values for rows and columns will be mapped onto a rectangular grid of 300 m resolution: the SYN Level-2 reference grid, similar to the OLCI acquisition grid associated with the OLCI reference channel.
