To do that, the modeller has to create a subdirectory under /lustre/storeB/project/fou/kl/emep/Web/AeroVal and link the data-directory to that directory, e.g. for the heikok_project:
# on PPI, e.g. ppi-r8login-b1
cd /lustre/storeB/project/fou/kl/emep/Web/AeroVal
mkdir heikok_project
cd heikok_project
ln -s /lustre/storeB/users/heikok/path/to/my/data .
The data is then available at http://aeroval-test.met.no/heikok_project and will be shown with the latest aeroval visualization.
