To do that, the modeller has to create a subdirectory under /lustre/storeA/project/fou/kl/emep/Web/AeroVal and link the data-directory to that directory, e.g. for heikok:
# on PPI, e.g. ppi-r8login-a1
cd /lustre/storeA/project/fou/kl/emep/Web/AeroVal
mkdir heikok
cd heikok
ln -s /lustre/storeA/users/heikok/path/to/my/data .
The data is then available at http://aeroval-test.met.no/heikok and will be shown with the latest aeroval visualization.
