Every year the Steering Committee Meeting of the Chacaltaya Global GAW station gathers in order to discuss scientific advances and other topics. This year the group was also celebrating the upgrade of Chacaltaya GAW station from Regional to Global. Moreover, this year's meeting was highlighted by the presence of Lorenzo Labrador in representation of the WMO-GAW program, Stéphane Sauvage as the head of the ACTRIS program, Gisella Marincovich on behalf of the Ushuaia global GAW station, Luis Suarez from Huancayo IGP GAW observatory, Johan Rojas of Senamhi-Peru GAW Marcapomacocha station, Julio Warthon from Cusco-Perú, and Carolina Concha from the Univ. del Desarrollo - Chile. The meeting was held in a hybrid manner with colleagues connected from other locations and this gathering provided the opportunity for fruitful community discussions.

During the last steering committee meeting, the post-graduate studies department of UMSA (DIPGIS) prepared a series of interviews related to the Chacaltaya GAW station.
In order to provide confidence that international standards on aerosol data gathering will be met at Chacaltaya GAW station, it underwent a technical audit performed by Dr. Alfred Wiedensohler on behalf of the ECAC. The station general setup and MAAP, nephelometer, MPSS and NAIS-5 operations were audited. This is part of a quality assurance strategy of the Chacaltaya GAW station, as any identified shortfalls will try to be solved to comply with GAW/ACTRIS reccomendations. After two years of virtual meetings, this year the Chacaltaya Steering Committee Meeting took place in La Paz. Sessions were held on the 26 and 27th September at the UMSA campus, but it was also possible to participante on-line. The main scientific results obtained in the last year were thoroughly discussed in a fruitful meeting, along with other matters related to future projects and the station operation. A distinction was given to Dr. Alfred Wiedensohler, Dr. Radovan Krejci, Dr. David Whitemann and Dr. Gaëlle Uzu on behalf of Dr. Paolo Laj, as a token of recognition of their support to Chacaltaya GAW station activities during the last 10 years.
A short steering committe meeting was held on line on the 23rd November 2022. The topics discussed were the review of current scientific programs and main findings, the status of different instruments, the scientific advances and the perspectives and plans for the Chacaltaya station and the urban sites of La Paz and El Alto.
Due to the covid-19 travel restrictions still on place worldwide, the annual steering committee meeting took place on-line on the 4th and 5th December 2020. From left to right and up to bottom: L.
