Seamless 30 meter Sentinel-2 L2A Pan-European seasonal cloudless mosaics from winter 2018 to spring 2020

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, 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.

The data are provided as UINT8 values and were scaled with a common threshold (13712) chosen to minimize compression loss across the dataset. Data at the original (UINT16) scale can be obtained as follows:

\(x_{\text{uint16}} = 13712 {x_{\text{uint8}} \over 254}\)
