Period: 1999 – present

Sensor: SPOT-VGT and PROBA-V

Frequency: 10 days

Resolutions: 1km

Extent: Global

Algorithm description: The algorithm is based on neural network and is same as described for Copernicus BioPAR GEOv1 LAI product.

Accuracy: Direct validation with ground-based data showed RMSE and R2 equal to 0.078 and 0.889 respectively. For comparison,  direct validation for other available products resulted in: RMSE = 0.108 and R2 = 0.779 (Camacho et al, 2013).


  • This accuracy tests were calculated using SPOT-VGT time series. However, since 2014 data come from PROBA-V. Products derived from PROBA-V have shown less accurate results than those from SPOT-VGT.
  • The GEOV1 product is not gap-filled.
  • Large gaps in products over northern latitudes in wintertime and equatorial areas.
  • Larger fraction of missing values on PROBA-V products than on SPOT-VGT products due to stricter cloud masking algorithm.
