Joint ALADIN/HIRLAM Newsletters

ALADIN and HIRLAM are jointly publishing their ALADIN - HIRLAM Newsletters since September 2013.

The aim is to do this twice a year: one edition around summer (dedicated to the joint All staff Workshop in spring) and one edition in the winter season.

If you have a contribution for the newsletter please contact the ALADIN secretariat (at MF) and the HIRLAM secretariat (at KNMI).


contributions for the 11th common ALADIN/HIRLAM Newsletter
deadline: early August 2018
  • will be mainly devoted to the presentations given by ALADIN and HIRLAM staff at the joint Wk/ASM 2018 in Toulouse
  • will give a focus on:
    • the recent doctors (if any)
    • articles just published
  • will list the future events such as scientific meetings, working weeks, working days
  • and: any additional contribution is also very welcome!


Please be reminded:
