Please, who can advise us, which atmoshperic correction are best for Sentinel 2 data?
in literature review, the Sen2Cor method were frequently used for atmospheric correction of Sentinel-2 imagery.
I agree with Amir, but normally new Sentinels don't need for corrections..
Dear karel
I applied sen2cor for doing sourface reflectance on Sentinel L1C format.
It is very good.
The spectral profile after correction for vegetation,soil and water was precision
It was better than FLAASH on Landsat 8
Dear Karel,
There are many tools for that, and you can compare the results in your images:
* Sen2Cor Software of @ESA: http://step.esa.int/main/third-party-plugins-2/sen2cor/
(Software easy to use in college, University context or work).
* Maja Software (ancient MACCS) of @CNES and @CESBIO: http://www.cesbio.ups-tlse.fr/multitemp/?p=14980
A little difficult to use, but strong in their results. (Personal advice).
... in my opinion, Maja is better for cloud detection and atmospheric corrections in my study Area (Latin America). But, it is better to take a little area and test the 2 software in your case.
On the other hand, there are images in level 2A corrections now, delivered by ESA (atmospheric corrections included) for Europe and Africa. They have plans to do the same for the entire world.
If you want to know more about Sentinel-2 work, corrections, time series analysis, there is an interesting Cesbio blog that explains many topics about that (agriculture included).

Dear Mostafa,
Maja software is not yet in Windows.
But linux version is ok!, linux it's not as difficult as it seems! :) . You can try with Redhat or Ubuntu.

Dear Luz-Maria ,
Thank you for your respansibility
Can i use them on the Wndows?
Thanks regards,
Dear Mostafa, in Windows you can use a virtual Machine to run MAJA.
Best regards,
Dear Karel, in this link you can find a recent paper about atmospheric correction and cloud detection for Sentinel-2 using Sen2Cor or Maja tools.

Hi everyone!
You also can correct Sentinel 2 imagens using the Semiautomatic Classification Pluguin (SCP) for QGIS, by the DOS1 method. DOS1 is a great and simple method to atmospheric correction ( Article Atmospheric and Radiometric Correction Algorithms for the Mu...
).SCP is a very good, free and intuitive tool, and tutorials to learn SCP management are available in https://www.researchgate.net/project/Semi-Automatic-Classification-Plugin.

Dear Karel , you can try acolite, it works well with sentinel ,
Here is the link of acolite

Dear Karel,
Please be more specific, for studies on water or on the continent?
Best,
SY
Hello, look at this and maybe you get some idea, which AC from those compared there is best for you.
