BIOGRAPHY HIGHLIGHTS
•    PhD position at The Norwegian Polar Institute and University of Tromsø, 2002-
•    M.Eng. in Physics from University of Tromsø, 2002

MAIN SCIENTIFIC INTERESTS
I’m interested in optical properties of snow and sea-ice, covering in-situ field measurements, remote sensing and modeling. I’m also interested in how aerosols (in particular black carbon) affect the spectral signature of snow albedo.
Take a look at: www3.npolar.no/~xtina for more information.

CURRENT ACTIVITIES/PROJECT INVOLVEMENT
•    Parameterization of snow and sea-ice albedo in ECHAM5 General Circulation Model (NFR, PhD project)
•    Climate effects of reducing black carbon emissions (NFR, Postdoc project)
•    Measurements of Black Carbon aerosols in Arctic snow - interpretation of effect on snow reflectance (NFR)
•    Forskningsprosjekt på biomembran som klimatiltak: Undersøkelser av bio-membran med hensyn på overflate-albedo og jordsmonn (NPI project leader)

FIELD WORK/CRUISE
•    Black Carbon field work in Ny-Ålesund, Svalbard (2007)
•    Fram2005 cruise in Fram Strait, Arctic Ocean (2005)
•    AIO field work in Van Mijenfjorden, Svalbard (2004)
•    CLPX field work in Colorado, USA (2003)
