I have Level-2 swath data files. i am interested to know how can i convert them to Level-3 gridded data files ?

multiple swath files are available on each day, i would like to merge and make a daily file. and i would like to overlay that data on the uniform grids of a particular resolution and save the daily output to a gridded netcdf file.

I have already tried HARP package in python it does not work.

please any help will be appreciated.

Thank you.
