JNCC Sentinel-2 indices Analysis Ready Data (ARD) Normalised Difference Vegetation Index (NDVI) v2
Abstract
NDVI is a widely used index that quantifies vegetation greenness and can provide an indication of vegetation health and vegetation density. It is calculated as the ratio between the near-infrared (NIR) and red bands. Positive values generally correspond to vegetation, with higher values reflecting healthy, dense vegetation.
NDVI = (NIR – RED) / (NIR + RED)
Sentinel-2 NDVI (Defra/JNCC ARD bands) = (B07 – B03) / (B07 + B03)
Equivalent ESA Sentinel-2 bands: B08, B04
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.
These data have been created by the Joint Nature Conservation Committee (JNCC) as part of the “Earth observation-based habitat change detection” project. This project is funded by the Department for Environment, Food and Rural Affairs (Defra) as part of the Natural Capital and Ecosystem Assessment (NCEA) programme. The project seeks to facilitate the effective uptake and use of Earth Observation data by producing data and tools for investigating and detecting parcel-level change in habitats and habitat condition.
The dataset contains NDVI, NDMI, NDWI, NBR and EVI2 indices derived from Defra and JNCC Sentinel-2 ARD. Index files have been generated for Sentinel-2 granules covering England and Scotland for the period from 2015 to 2025. Note that new unmasked index files (v2) have superseded the previous masked index files (v1). Masked files will no longer be produced. Users can mask the new index files if required using the cloud and topographic shadow masks provided with the ARD, or masks of their choice.

Contains modified Copernicus Sentinel data 2015-2025 Data were produced by the project team and supplied for archiving at the Centre for Environmental Data Analysis (CEDA). |
| Data Quality: |
All index files are quality checked automatically as part of the processing workflow. The QC process checks that the following are as expected: the data value range, file format, coordinate reference system, no-data value, data type, pixel size, pixel alignment with the source ARD file. As part of workflow testing, a representative subset of data was also manually checked. Data are as given by the data provider, no quality control has been performed by the Centre for Environmental Data Analysis (CEDA).

| Title | Computation for JNCC Sentinel-2 indices Analysis Ready Data (ARD) Normalised Difference Vegetation Index (NDVI) v2 |
| 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. NDVI 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.
