The University of Hamburg have supplied a spectral radiometer. Contact Mayk Fischer :mayk.fischer@zmaw.de. The University of Lancaster and the Oceanographic Institute at Southampton have filter samplers at the Observatory. For more details contact Matt Patey at: mpatey@noc.soton.ac.uk and Luca Nizzetto at: luca.nizzetto@uninsubria.it or Rosalinda Gioia at : r.gioia@lancaster.ac.uk. Radiosonde measurements are made on the nearby island of Sal, providing information on the physical structure of the boundary layer. A Multi-Axis DOAS from the Institute for Environmental Physics, University of Heidelberg, Germany (http:\\www.iup.uni-heidelberg.de) is now also in place to provide information on the optical properties of aerosols, IO and BrO measurements (U. Platt, U. Frieß and J. Balbo). During short term "intensive campaigns" further measurements could be added to this suite, e.g. RHaMBle, SOS (Future
campaigns/measurements at the site)
If you would like to do some science at the CVAO please complete the facility request form and e-mail to km519@york.ac.uk. |
