C2RCC for MSI using NASA ancillary data (ozone and pressure)



I am using SNAP V6.0 and I m trying to use ancillary data in the C2RCC processor for Sentinel-2 MSI products.

I download AURAOMI and NCEP data from ‘[https://oceandata.sci.gsfc.nasa.gov/Ancillary/Meteorological/]’, and I use the .hdf files downloaded as input for the c2rcc processor.

The processor works fine, however, the outputs from c2rcc have now the resolution of my ancillary data ~1degree. Am I doing something wrong? Should I use other ancillary products?

Thanks for your help!
