These data have been created by the Department for Environment, Food and Rural Affairs (Defra) and Joint Nature Conservation Committee (JNCC) in order to cost-effectively provide high quality, Analysis Ready Data (ARD) for a wide range of applications. The dataset contains modified Copernicus Sentinel-2 (Level 1C data processed into a surface reflectance product (Level 2)). Defra and JNCC data were processed on separate platforms using a common specification to produce complementary outputs.
The majority of data captured between July 2015 and August 2017 was processed by Aberystwyth University for Defra and later updated by JNCC to the same specification as the rest of this dataset. Please see the image-level metadata for details of data lineage and processing.

|Title||Computation for Defra and JNCC Sentinel-2 Analysis Ready Data|
|Abstract||Sentinel-2 Level 1C products processed into a Level 2 surface reflectance product using ARCSI ( https://www.arcsi.remotesensing.info/ ). Processing used the following steps: re-projection to either OSGB 1936/British National Grid (EPSG27700) or TM65/Irish Grid (EPSG:29902), band sharpening to 10m (removing the native 60m ESA Bands 1, 9 and 10), cloud masking, atmospheric correction and topographic correction using either the Aerial Photography Great Britain (APGB) 10m resolution DEM or the Ordnance Survey Northern Ireland (OSNI) 10m resolution DEM. Please see individual image metadata for the versions of software used in processing.|
