b) optical measurements (AP, int. Nephelometer)

c) chemical measurements (OC/EC, ACSM)

d) other technical questions.

3. The ACTRIS In Situ Data Centre unit will offer an intensive support period for your questions around data reporting. Between 17 – 21 May 2021, we will have increased focus on responding to your questions (via ebas@nilu.no) as fast as possible.

4. Our DC In Situ colleagues Ann Mari and Yong will give lectures on the data reporting process at the Hyytiälä winter school next week. The lectures will be turned into videos. These videos will be made available as educational material for your help (by separate mail once available).

8. ECAC und the DC created a new email list of the ACTRIS aerosol in-situ community hosted by the data center (this email was sent by this email list)

9. We are sure that this email list in not complete yet, since we don’t know all interested people, especially from the new coming up National Facilities. We would like ask, if you could possible inform also your colleagues about this list. If they want to be added, they should write an email to Markus Fiebig (mf@nilu.no).
