On 1st and 2nd July 2013 the steering comitee meeting of the CHC-GAW scientific consortium was held in La Paz. The LFA was honoured with attendees of most of the consortium:
From the 24th June to the 1st July 2013 an international school course on atmospheric aerosol physics, measurement, and sampling was organized by the Laboratory for Atmospheric Physics (LFA), La Paz, Bolivia in collaboration with the Leibniz Institute for Tropospheric Research (TROPOS), Leipzig, Germany. The lecturer was Prof. Dr. Alfred Wiedensohler (TROPOS), a widely recognized expert on the topics of the course, who is currently editor in chief of the Journal Atmospheric Environment and the head of the World Calibration Centre for Aerosol Physics of the WMO World.
Interesant courses were organized by the LFA and held at the UMSA campus of Cota Cota by the end of 2012:
Aerosol Chemistry, given by Paolo Laj, PhD., a recongized expert in the aerosol science field, experienced in different sampling environmnents, from the french lowlands to the nepalian highlands and current director of the LGGE of Grenoble (20th to the 23rd of November). Atmospheric Aerosol Teledetection, an extensive course lasting from the 29th of November to the 5th of December, was given by the young researcher Daniel Perez, PhD. from the University of Granada (now at the Goddard Space Flight Center, NASA, USA). On 7th December, David Whiteman, PhD. (Goddard Space Flight Center, NASA, USA) delighted us with an unforgettable seminar about the history of LIDAR systems. M. Whiteman shares his vast experience working on LIDAR instruments with the LFA by acting as the prime mover of the installation of a LIDAR system at the campus of Cota Cota. The Chacaltaya GAW station was officially inaugurated the 3rd of april 2012. The university authorities and members of the scientific consortium were present. Observations of the free troposphere are needed to understand long-range transport, climate change and trends in the oxidizing capacity of the atmosphere, as well as to provide a baseline for the characterization of atmospheric chemistry and physics. A review of global networks shows that the Southern Hemisphere is clearly under-sampled in comparison to the Northern Hemisphere and, although this is partly due to the predominance of oceanic surfaces, it is also due to both the lack of monitoring stations on land and the restricted number of dedicated field campaigns in vast areas of the Southern Hemisphere.A consortium of scientific institutions(1) has proposed and carried out the implementation of a long-term station at Mount Chacaltaya (16º21'S, 68º08'W, 5300 masl) operated by the Laboratory for Atmospheric Physics (Laboratorio de Física de la Atmósfera, LFA-UMSA) with the potential to become the 3rd. GAW global station in South America and a unique high-altitude station over the continent.The new station has begun operations on December 2011. After some infrastructure refurbishing at the station and the installation of a brand new weather station at the summit (part of the SENAMHI network) all instruments were installed and are currently working (see photographs). In addition, a LIDAR system has been used on a regular basis since 2011 at the LFA to characterize the boundary layer and it will be used in the future to study the BL evolution in the vicinity of the new CHC-GAW station.
With this letter I would like to confirm that we have considered your project entitled "The implementation of a regional GAW station at Chacaltaya (5320 m., Bolivia)" and obtained an oficial letter of support for this project from the Permanet Representative of Bolivia with the World Meteorological Organization (WMO).
