Propagated Sentinel-2 Radiometric Uncertainties in NDVI, EVI and GLAI for an Entire Growing Season

Radiometric uncertainties were propagated from Sentinel-1 top-of-atmosphere reflectance factors via atmospheric correction with Sen2Cor into two spectral indices EVI and NDVI (Enhanced Vegetation Index and Normalized Difference Vegetation Index) and the green leaf area index (GLAI) from inversion of the radiative transfer model ProSAIL using Monte Carlo simulation. The radiometric uncertainties are from the Sentinel-2 L1C Radiometry Uncertainty Toolbox.

The Monte Carlo framework used is freely available in github.com/remote-sensing-team/s2toarup under GPL v3 license and allows full reproducibility of the results deposited in this Research Collection. The Collection contains the original NDVI, EVI, and GLAI values for 34 Sentinel-2 scenes covering an entire growing season, as well as the associated standard uncertainties (k=1) from Monte Carlo propagation of the radiometric uncertainties.
