Resources and Data

Data for Download

  1. Continuous soil temperature and moisture records for various vegetation types and for the birch hummock snowfence and greenhouse experiments at a low arctic tundra site since 2006 at 4 hourly and diel frequencies (Daring Lake, NWT, Canada). (Soil temperature and moisture diel data download (3.8MB)ReadMe file) (Comparable 4 hourly data are also available via Dropbox etc). Please contact Paul for details if you wish to use any of these data in a publication.
  2. CO2 emissions calculator for travel by small fixed-wing and helicopter aircraft as well as travel by commercial aircraft, rail or road.
