Level-2 Land LRR and LFR
The OLCI Level-2 land reduced or full resolution products, OL_2_LFR and OL_2_LRR respectively, are outputs from the OLCI Level-2 processor and contain land and atmospheric geophysical products at full and reduced resolutions.
The content of these files depends on several switches included in the OLCI configuration parameters. Each geophysical parameter format is only triggered if the corresponding switch is set to ‘1'. Note that all pixels flagged as cloudy are discarded from OLCI Level-2 processing.
The only difference between OL_2_LFR and OL_2_LRR products is the spatial resolution, with a spatial sampling of approximately 300 m for full resolution and 1.2 km for reduced resolution. The products are assumed to be computed in near real-time (i.e. delivered to users less than 3 hours after acquisition), in non-time critical (i.e. within 1 month after acquisition) or in re-processed non-time critical.
Each product provides as measurement data files (more fully described in the table below):
Several associated variables are also provided in the annotations data files:

The classification, quality and science flags provide information about validity, suspicious quality, cosmetic filling, environment and input quality.
