Climate scientist and astronomer

Danish Meteorological Institute, Copenhagen

I am a climate scientist and astronomer at the Danish Meteorological Institute. My work includes extreme-value statistics, climate variability, Earthshine and terrestrial albedo, time-series analysis, remote sensing, astronomical image analysis, and scientific software.

Research and projects

Earthshine & Earth's albedo

Measuring light reflected by Earth onto the dark side of the Moon, with the aim of monitoring terrestrial reflectivity and understanding instrumental and scattered-light effects.

Climate extremes

Statistical work on extremes, climate variability and change, including sea level, temperature and precipitation.

Astronomical image analysis

Wide-field and fisheye astrometry, lunar image analysis, calibration, PSFs, scattered light, and methods for extracting quantitative information from difficult astronomical imagery.

Scientific software & electronics

Small tools and experiments for astronomy, data analysis, cameras, Raspberry Pi, Arduino and laboratory work.
