Guus Velders MD, PhD

Guus Velders studied applied physics at the University of Twente where he obtained his PhD in quantum chemistry . From 1992 to 1993 he worked at the Royal Netherlands Meteorological Institute (KNMI) and from 1993 to 2005 and since 2011 at RIVM. In 1999 he worked at the Aeronomy Laboratory (NOAA, USA) and from 2006 to 2010 at the Netherlands Environmental Assessment Agency (MNP, PBL).

Velders worked mainly on scenarios and modeling of the ozone layer. Later he focused on air quality at the European and national level. As project leader of the large-scale concentration and deposition maps for the Netherlands (GCN/GDN), he was responsible for the air quality data for local models since 2006. This data became part of the National Air Quality Collaboration Programme (NSL) and the Programme Approach Nitrogen (PAS).
