Inputs (atmosf_reflect) to L4A,L4B processors

Hi,
I was not able to find exact infomrmation about data inputs (L2A products) for L4A and L4B processors.
In my analysis I created all outputs from the Sen2Agri system - I have L2A, and also L4A and L4B products.

My question to the authors of the system is, where I can find the L2A data which are applied into L4A and also L4B processor?
I was checking the product data structure summary, but there was no explanation on L2A dir structure.
I was also searching inside the manual, e.g in the example of manual execution from terminal, where all the parameters of script execustion are listed, but I was not able to identify if the reflectance data are somewhere stored… (?)
For example, the data (one tile product of L2A) are as follows:
L8_TEST_L8C_L2VALD_189026_20181015.DBL.DIR
demmaccs.log
demmaccs_189026.log
L8_TEST_L8C_L2VALD_189026_20181015.DBL
L8_TEST_L8C_L2VALD_189026_20181015.HDR

please, could somebody help me or direct me where it is possible to find the data structure example.
or maybe are the reflectance data stored only temporarly inside the Sen2Agri and after the products (L4A/L4B) are generated the data are deleted?

thank you very much for any help,
eva

Dear Eva,

L2A products are created inside Sen2Agri system using MAJA processor.
The structure of the output L2A products created with MAJA can be found on CNES site:


and for “native” format (which is still preserved for L8 products):
http://www.cesbio.ups-tlse.fr/multitemp/?page_id=10464

Please note that the Sen2Agri also supports as input L2A products created with ESA Sen2Cor and in this case you should have a look on the outputs structure of this processor.

Best regards,
Cosmin
