Thank you for your answers. I have carried out some tests with 1C and 2A images of the same day and 2A values are usually higher due to the reflectance correction. I wonder to know if the time of the day when the image is taken (or in other words: the amount of light or the height of the Sun) affects to the real values of the NDVI.

Hello: I am working with Sentinel 2 images to generate NDVI maps, using QGIS. I create the NDVI image with the raster calculator using the formula NDVI=(NIR-R)/(NIR+R), but I wonder how do other factors such as cloud shadow or the previous treatment of the images. I also would like to know the difference of working with the 1C data or the 2A data to get NDVI values.
