Atmospheric Correction of Sentinel-2 Images Using Sen2Cor | Convert L1C (ToA) to L2A (BoA)

OSRSGIS
Atmospheric effects in optical remote sensing can significantly alter reflectance values and lead to erroneous results. Thus, atmospheric correction is arguably the most important step in the preprocessing of satellite imagery. This tutorial shows how to implement Sen2Cor processor to derive Sentinel-2 surface reflectance products (Level 2A) from top-of-atmosphere reflectance products (Level 1C).

We can also reach the folder in Windows following 2 easy steps
1) Go to the folder using files explorer
2) Type "cmd" (without quotes) on the address bar

Excuse me, I would like to know that why the BOT reflectance value was less than the TOA reflectance value?

Thank you so much !
Is there any way I can perform a batch of images at once.

how i can calculate turbidity from? is that possible?

Thank you very much for this tutorial. I have a question: Is it possible to perform the process for multiple images at the same time? I have to process around 60 images and it would be perfect to be able to do it all at once.
Thank you!

Thank you very much. One question: after this procedure, would it be ok to compare the ndvi of one image from 2016 with the ndvi of another image from 2022?

Hi. Is it possible to perform the process on a merged image

Are other corrections needed for sentinel 2 a msi level 2a such as atmospheric correction or positional correction?
