SEN2COR tool


Agreed, I’d recommend 8GB and a 64-bit operating system as the baseline setup.


Its tru… I try 8GB…And now everting its fine…But the band 8 after the process disappeared


Dear Uwe, Sorry to trouble you, could you tell me the QUANTIFICATION_VALUE of Sentinel-1C is 1000 or 10000? I found the QUANTIFICATION_VALUE for Sentinel-1C and 2A in the header file is <QUANTIFICATION_VALUE unit=“none”>10000</QUANTIFICATION_VALUE>, but other people said QUANTIFICATION_VALUE for IC is 1000 and 2A is 2000. could you tell me what is right? thank you very much!


As this value can change over time and for various products I would trust the one in the image’s metadata:


but other people said QUANTIFICATION_VALUE for IC is 1000 and 2A is 2000. could you tell me what is right? thank you very much!
This is long time ago. The correct is stated in the L1C metadata with 10.000.


OK I see , thank you very much


That happened to me as well. I think, after a few times of uninstalling and installing via the TOOLS>PLUGINS widow I finally just ignored the error and it processed fine.


Ok i install sen2cor. Now what can i do next? How i save the result of sen2cor process?i don’t know how to process the image , can you help me?

thanks in advance


Hi All,
May I know whether the sen2cor only applicable to the whole scene only and not the granule level?


you can perform atmospheric correction for all scene (images released before 2016-09-26) and also for single Granules. Its depend on picture and what you want to do with this. For single Granules for few tiles eg(for one date Granules UXT UXV UXU) I used R software in order to set a queue and pefform process



Hi Kiryl,
I have tried for the granule (1 tile image) but here is the error code

Is it because of the folder directory name?


try to set folder eg in D disc D:\S2A_OPER_PRD…
if in folder Granules have more than one Granules (in your case I think its 13-15 single tiles you have two ways: First remove all Granules which are not interested fore you, second change the name for Granules are not interested for you. I used symbol ~before name (eg. S2A_OPER_MSI_L1C_TL_SGS__20151231T141323_A002736_T34VDH_N02.01 I get ~S2A_OPER_MSI_L1C_TL_SGS__20151231T141323_A002736_T34VDH_N02.01). Latest you have in command line write this: L2A_Process (path to folder where you find xml files S2A_OPER_MTD_SAFL1C_PDMC_20151231T175113_R022_V20151231T102248_20151231T102248.xml and optionaly resolution)
It seems like this L2A_Process D:\S2A_OPER_PRD_MSIL1C_PDMC_20160401T003323_R018_V20160330T034406_20160330T034406.SAFE (optionally --resolutions 10



Hi Kiryl,
Thanks. It is working good now.
Best regards


In order to get reflectance value, bath math using in Radiometric conversion of sentinel 2 images can be used?


unfortunately I dont know. I never performed this operation

Best Regards


Thank you Kiryl.



I have the same problem but when I change the path PYTHON doesn’t work (see scceenshot)!!
In my case sen2cor doesn’t exist in Anocanda2 files but in Python27. What should I do?
Thank you


try to copy files Sen2Cor from Python27 to Anaconda2 folder.



Hello @ABraun ,

I installed the version sen2cor-2.3.0 but I find in operator descriptor another version 2.1.2

Please, is that the configuration of the varibles system is correct ???

thank you in advance


I followed your advice and I copied the folder and now I have this error …
