Vegetation and meteorological observations (snow and radiation) were collected by various ground instruments in an area of forest near Abisko (Sweden) and Sodankylä (Finland) during measurement campaigns in March 2011 and March 2012. This dataset contains the data produced by a Vaisala WXT520 weather transmitter used to measure temperature, relative humidity, wind speed, wind direction and atmsopheric pressure during the radiometer experiments in each plot in March 2011. This was a NERC funded project.

Vegetation and meteorological observations (snow and radiation) were collected by various ground instruments in an area of forest near Abisko (Sweden) and Sodankylä (Finland) during measurement campaigns in March 2011 and March 2012. This dataset contains the trunk temperature data collected at Abisko site in March 2011. Trunk temperatures for selected trees in the continuity plots were measured by inserting thermocouples beneath the bark. This was a NERC funded project.

The ABACUS (Arctic Biosphere-Atmosphere Coupling at multiple Scales) research project is a major, linked programme of plant and soil studies, atmospheric measurements, aircraft and satellite observations, and modelling, to improve our understanding of the response of the arctic terrestrial biosphere to climate change. The data collected as part of the ABACUS Work Package 1 (Studies on plant allocation and phenology, and respiration-production ratios for major community types (via harvests, root measurement and isotope tracer experiments) includes root measurements and isotope ratios of plants as follows: Plant data for WP1 harvest and ingrowth core plots, Abisko (Sweden), 15 Jul 2007 - 08 Aug 2007 - Fine Root Length, Abisko (Sweden), 15 Jul 2007 - 08 Aug 2007 - Leaf and stem C and N, Abisko (Sweden), 15 Jul 2007 - 08 Aug 2007 - Fine Root Length, Kevo (Finland), 01 Jun 2008 - 03 Sep 2008 - Leaf and stem C and N, Kevo (Finland), 01 Jun 2008 - 03 Sep 2008
