Seasonal composites of Sentinel-2 L2A imagery created as part of the Geo-harmonizer project, containing median of the blue, green, red, NIR, SWIR1 and SWIR2 bands (see complete list), as well as pixel counts per season, produced in the ETRS89-extended / LAEA Europe (EPSG:3035) spatial reference system.

Mosaics were produced from winter 2017 to spring 2020, with the imaging intervals per season being:

  • winter: 02/12 of previous year to 20/03
  • spring: 21/03 to 24/06
  • summer: 25/06 to 12/09
  • fall: 13/09 to 01/12

Seamlessness of the composites was achieved through overlapping pixel averaging weighted by distance from the suborbital track.
