VAPOR stands for Visualization and Analysis Platform for Ocean, Atmosphere, and Solar Researchers. It is a software system providing an interactive 3D visualization environment that runs on most UNIX ,Windows and Mac systems equipped with modern 3D graphics cards. The home of the software is https://www.vapor.ucar.edu :

ECMWF GRIB data in VAPOR?
VAPOR has it own internal data model and any data to be visualised has to be converted into this VAPOR format. There are a set of command line tools that can convert NetCDF input data into the VAPOR format but there is no such tool available for GRIB.
Metview's VAPOR Prepare icon helps to overcome this difficulty and allows converting ECMWF GRIB data into the VAPOR format. For detailed instructions
Once the data has been converted just right-click Visualise the VAPOR Prepare icon to start up VAPOR with the newly created dataset.

VAPOR data files
VAPOR input data is described by .vdf (VAPOR data Format) files. These are XML files containing the name and dimension of all the variables and the path of the actual data files storing the data values. VAPOR stores its actual data values in .vdc (VAPOR Data Collection) files. These are NetCDF files containing wavelet compressed 3D data. There is a separate file for each variable and timestep organized into a folder hierarchy.
