ACTRIS CiGas Community Workshop 2024: Advancing Collaboration and Data Excellence

Matera, Italy – November 7, 2024

The ACTRIS CiGas Community Workshop 2024, held during the ACTRIS week 2024 in Matera, Italy, brought together representative from the National Facilities of the ACTRIS Centre for Reactive Trace Gases In Situ Measurements (CiGas) and CiGas unit heads. This hybrid event, accessible both in-person and online, provided an opportunity to share updates, foster collaboration, and advance data management practices in the CiGas community.

With the ever-growing importance of high-quality atmospheric data in addressing global environmental challenges, this workshop provided a platform for participants to share updates, exchange ideas, and discuss the implementation of methodologies.

Attendees explored strategies to enhance the reliability and accessibility of observational data, with a strong focus on fostering transparency, inclusivity, and collaboration within the atmospheric research community.

The program featured a lineup of speakers and sessions, covering topics from data portal advancements to instrument auditing and database development.

These discussions underscored the community's collective commitment to advancing data quality standards and ensuring the utility of atmospheric observations in scientific and policy contexts.

Lidar QA/QC workshop 2024

16 Jul
/
16 Jul

CARS and ARES invite the Principal Investigators of the aerosol remote sensing facilities to discuss the status of the lidar QA/QC. The workshop is organized online, 9-12 December 2024. Each lidar has a dedicated 30 minutes time slot to clarify aspects related to performances of the instrument as identified through the QA tests, specifics and validity time period of the operational configurations, and data processing with the SCC.

Details about the format of the workshop are distributed via the aerosol remote sensing mailing list. Please contact Doina Nicolae (nnicol@inoe.ro) for additional information.

ACTRIS Aerosol Remote Sensing Workshop November 2024

16 Jul
/
16 Jul

ACTRIS Center for Aerosol Remote Sensing (CARS) and the Aerosol Remote Sensing unit of the ACTRIS Data Centre (ARES) organize a joint workshop on 7th November 2024, as part of the ACTRIS Week. The workshop is organized in hybrid format, however, we encourage the community to join us physically in Matera, Italy.

The focus of the workshop is on the global perspective of our work, operations, quality assurance and data products. A joint session with the cloud remote sensing community is planned at the end of the day, focusing on the EarthCARE Cal/Val pilot, as well as on the future development of synergy products based on aerosol and cloud remote sensing instrumentation. ACTRIS aerosol and clouds remote sensing teams and their collaborators are welcome to join. Please register via the ACTRIS Week registration platform by selecting the appropriate form of participation under "CARS-ARES (aerosol remote sensing) workshop, Thu Nov 7".

Registration is open by 4th October 2024.
