CVAO-Observatório Atmosferico de Cabo Verde Humberto Duarte Fonseca*

 2015 capeverde

The Cape Verde Atmospheric Observatory, CVAO (16° 51' 49 N, 24° 52' 02 W) is a World Meteorological Organisation-Global Atmospheric Watch (WMO-GAW) global station and quality-assured atmospheric data for use by both UK and German scientists, and the wider international community are regularly deposited at both the WMO-GAW and British Atmospheric Data Centre (BADC) data archives. The University of York, provides the CVAO trace gas measurements (O3, CO, NO, NO2, NOy, VOCs, halocarbons, TGM), supported by the Natural Environmental Research Council (NERC) through the National Centre for Atmospheric Science's (NCAS) Atmospheric Measurement Facility (AMF). The Max-Planck-Institut für Biogeochemie, Jena, Germany (MPIB Jena) make the greenhouse gas measurements, and the Leibniz-Institut für Troposphärenforschung, Leipzig, Germany (IfT) measure various characteristics of aerosol. Collaboration is also with the Instituto Nacional de Meteorologia e Geofísica, São Vicente (INMG), who provide logistical support and employ staff at the CVAO. The sister ocean site is a partnership of the Instituto Nacional de Desenvolvimento das Pescas, São Vicente (INDP), and the GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany (GEOMAR Kiel). Scientific activities at both sites are coordinated in collaboration with the above institutions.


Scientific Objectives

1. To provide a long-term record of inter-annual variability and trends in marine tropospheric composition and associated meteorological, geophysical and oceanographic factors

2. To investigate biogeochemical processes important in regulating atmospheric composition and climate, particularly those associated with ocean-atmosphere exchange, dust deposition, and pollution.

3. To provide a regional focal point and long-term data context for short-term campaigns, experiments and process studies in the marine tropics.


30m Meteorological data can be found here.

We also have a Gill Windsonic, installed December 2014. This wind rose shows the stability of the wind at the site and the dominance in the site receiving air from the north easterly direction.

* Humberto Duarte Fonseca studied the climatology, meteorology, oceanography and ecology of the Cape Verde area and published numerous papers in the 1950s-1970s. He died in 1982. His work was primarily devoted to ameliorate the living conditions on Cape Verde (e.g. fisheries, production of wind energy).
