There are four tar files containing data and scripts
to intercompare the AMVs with other data centres, model
reanalysis grids, and RAOBs:

amv_dataset.tar.gz: Text files of AMVs
grid.tar.gz: ECMWF reanalysis grids
raob.tar.gz: Text file of RAOB data
amv_scripts.tar: bash, MATLAB, and Python scripts

All four tar files are needed and should be
extracted in one directory. 

Each tar file has a README file with information
on the contents of the tar file and documentation
of the scripts. Also, there is information on versions
of MATLAB and Python, which were used to run the scripts.
