Dear ACTRIS Aerosol In Situ Community,
For your information and consideration, the upcoming Summer School on Formation and Growth of Atmospheric Aerosols, which will be held in Hyytiälä, Finland, from 17–27 August 2026.
The summer school will bring together students and early-career researchers from across the field, offering lectures, hands-on activities, and opportunities to exchange ideas with leading experts. In addition to being scientifically stimulating, it will provide a great chance to build connections within the atmospheric science community.
Sincerely, Silja Häme

Dear all,
We´re pleased to invite you to the 2nd OGTAC-CC community meeting that will be held online on April 28 from 1 to 4 p.m. CEST.
This is the second virtual community meeting within the framework of ACTRIS for all interested in QA/QC of particulate organic tracers (OTs). We invite you to a lively workshop where OGTAC-CC is presenting its current implementation status, latest news and future activities of the calibration centre.
On the one hand, this invitation is addressed to those NFs that officially indicated their interest in OT measurements from filters. On the other hand, we would like to invite in particular potential future NFs to inform about the current status and next steps connected to OGTAC-CC. NFs that indicated for example offline OC/EC measurements from filters are highly welcome to join this community meeting and to discuss potential interests, opportunities of OT measurements and applications.
We would be very glad for everybody to participate who could imagine that the activities of OGTAC-CC might be of any assistance for future ACTRIS work.
If you are planning to participate, please send a brief notice to: mothes[at]tropos.de
Please find attached the agenda of the meeting including the online zoom link.
We´re looking forward to get in touch with you.
Please feel also free to distribute this invitation to everybody interested.
All the best,
Falk and Hartmut

Dear community,
you can find the actual version of the "MPSS evaluation software with R" as a download under "Measurement Guidelines" -> "Particle number size distribution - mobility diameter 10-800 nm". Please use only the approved version by WCCAP to avoid any problems or mistakes during the evaluation process.
First information about the software were given during the last community meeting on February 12th, 2026. Please have a look at the presentation in the section "Meetings & Minutes".
