Abstract
Index equation from Sentinel Hub custom scripts (link in Related Documents). Sentinel-2 surface reflectance products are obtained from Defra and JNCC Sentinel-2 ARD CEDA dataset. NDMI index files are generated in R v4.4.1 (R Core Team, 2024) using the calc function of the R package raster v3.6-26 (Hijmans, 2023). Data are provided in EPSG: 27700 OSGB36 / British National Grid, with a pixel size of 10m, and data is pixel-aligned to the source ARD file. No-data pixels are set to a value of -9999.
