Technical audit to Chacaltaya GAW station

In order to provide confidence that international standards on aerosol data gathering will be met  and that any shortfalls will try to be solved,  Chacaltaya GAW station aerosol underwent a technical audit performed by Dr. Alfred Wiedensohler on behalf of the ECAC.
The station setup and the aerosol instruments were audited.  The instruments audited were the MAAP, the polar nephelometer, the MPSS and the NAIS-5.
This is part of a quality assurance strategy at Chacaltaya GAW station in compliance with ACTRIS and GAW reccomendations.
