Good morning,

I am working with Sentinel-5p products, my final thesis is to establish a methodology for processing this type of images, from downloading to the implementation of a colour map with the different distributions according to concentrations. Any help on this subject is of great help to me.

I download the products from ''Sentinel-5p Pre-operations Data Hub'', but the L2, ozone and sulphur dioxide products do not open in SNAP(Sentinel Application Platform) CO, NO and the aerosol index do open. I have read other forums and they tell me that they are not compatible and that I should download toolboxes, but I don't know how to do it.

I would be very grateful to anyone who has worked with me and would like to help me.

  • $\begingroup$ I'm not familiar with SNAP, but it's possible that the products not opening have different data elements or more dimensions than what SNAP expects. Are you using HDF files? $\endgroup$

  • $\begingroup$ Thank you for all the answers. @Jean-Marie Prival, do you know how I can incorporate these tools into SNAP. Or how I can make use of them? $\endgroup$ Jul 5, 2021 at 6:42
  • $\begingroup$ @f.thorpe Sentinel-5p products are netCDF files. $\endgroup$ Jul 5, 2021 at 6:43
