Sen2Cor missing a file needed for processing?

I can confirm that automated configuration is not working in some cases. This topic
describes another error I’ve had:

Sen2Cor ozoneContent error

Hi people, I encountered a new problem while trying to process some Sentinel-2 imagery to surface reflectance. This is the error message I get: [image] Here is the full error log :Error (14.0 KB) Here is the L2A_GIPP i used: L2A_GIPP.xml (4.1 KB) The name of the image in question is S2A_OPER_PRD_MSIL1C_PDMC_20160217T163715_R136_V20160217T093042_20160217T093042 , but I encountered this error on other images as well (on some tiles). Can anyone help please, or try to reproduce the error…

After varying the parameters Aerosol_Type , Mid_Latitude and Ozone_Content in the L2A_GIPP.xml,
I found out that the error only occurs when Aerosol_Type or Mid_Latitude are set to AUTO. This doesn’t happen with every tile of every image, but it happens. Trying to find out what was causing the error I added 2 print statements below line 3955 in L2A_Config.py:

print("OZONE MEASURED: " + str(self.ozoneMean))
print("MID LATITUDE: " + str(self.midLatitude))

This is the error output:
