This folder contains OLCI MPF v1.7, OLCI melt pond fractions, spectral albedo at 400,500,600,700,800,900, 
and broadband albedo calculated according to Pohl et al., 2020, under
https://data.seaice.uni-bremen.de/olci/$YEAR e.g. ../olci/2017/ and so on, till 2023.

The data were obtained using the MPD algorithm and cloud screened using the synergy OLCI/SLSTR as in Istomina et al., 2023.
Please visit https://seaice.uni-bremen.de/start/ for details.

The NetCDF files contain daily averages of the above quantities gridded onto 12.5km polar stereographic grid.
https://nsidc.org/data/polar-stereo/ps_grids.html

The coordinates are not included into the files and can be found here:
https://data.seaice.uni-bremen.de/olci/LongitudeLatitudeGrid-n12500-Arctic.h5

Swath data or grids with other resolutions are available on request: Larysa Istomina, lora@iup.physik.uni-bremen.de

The product is available for 1.May-30.September 2017-2023 (non time critical data, 2023 still in progress) 
Operational processing with near-realtime data is available 01.05.-30.09. with the delay of one day.
