The event will take place from September 2 to 5, at Ludwig-Maximilians-Universität (LMU) in Munich. 

Due to capacity constraints, the training school will accomodate a maximum of 40 participants. Priority will be given to Cloud Remote Sensing National Facilities and open to PhD students/researchers/expert scientists…. 

A draft program for the week is currently underway, including lectures and hands-on sessions. Morning sessions would host lecturers from CCRES/CLU and external for theoretical classes, while afternoons would be dedicated to hands-on/group work. All sessions will be on-site only. Topics covered will include CCRES services, instrument calibration, quality control, CloudNet products, Cal/Val, scientific applications, Cloud properties, etc. 

Please do not hesitate to send suggestions for topics or proposals for leading such a session, or use this form if you haven't already done so. 

More information will be published through this page.

Data Flagging Workshop (Online)

The ACTRIS CiGas Data Flagging Workshop took place on 24 of January 2025.

The aim of the workshop was to discuss and harmonize the definition of local events for VOC (Volatile Organic Compounds) and NOx (Nitrogen Oxides) data submission.

A new draft guideline for data flagging was presented, along with practical examples of different local events.There was a lively discussion on the use and application of different flags among the 53 participants.

The discussion will be continued at the CiGas Data QA/QC online workshop which will take place from April 7th to 9th 2025.

Registration is already open:
