Met.3D requires meteorological data on a regular lat-lon grid.The Data handling section provides an overview about the data that can be processed by supported data and file types in Met.3D. If you download ERA5 data on a regular grid, you should be able to directly load the data into Met.3D and start your visual data exploration. If the data is on a Gaussian or Spectral grid, you need to interpolate the data to a regular grid before you can analyse it using Met.3D. The Climate Data Operators (CDO) provide a convenient way to interpolate ERA5 data onto a regular grid.For a detailed documentation of CDO, please see: https://code.mpimet.mpg.de/projects/cdo/.
