  • This CD-ROM set contains the Volume 1 vegetation data collection. The data covers a 24 month period, 1987-1988, and all but one are mapped to a common spatial resolution and grid (1 degree x 1 degree). Temporal resolution for most datasets is monthly; however, a few are at a finer resolution (e.g., 6-hourly). This dataset contains data covering: * Background (soil/litter layer) reflectances * Fraction of Photosynthetically Active radiation absorbed by the green vegetation canopy (FPAR) * Fourier-Adjustment, Solar zenith angle corrected, Interpolated Reconstructed (FASIR) normalized difference vegetation index (NDVI) * Percentage green leaf area of total leaf area * Total Leaf Area Index (LAI) * Normalized Difference Vegetation index (NDVI) * Roughness length (Zo) * Calculated snow-free albedo * Global land cover classification from satellite data

  • QUERCC addresses land surface processes over timescales from days to centuries, with particular emphasis on the carbon cycle. Some processes are already well represented and validated in Dynamic Global Vegetation Models (DGVMs), while others that are known to impact on the carbon cycle are not. Independent carbon and vegetation data sets are being compared against DVGMs to assess their current state, and further key modules will be developed for nutrient cycling, which exerts a major feedback on carbon exchange, and for a greater resolution of plant processes. This dataset contains Imogen output model data

This dataset contains a global map of plant functional types that exert significant impacts on the carbon cycle as modelled by the Rothamsted Research institute based on the FAO (Food and Agriculture Organization) soil properties.

  • A hand-held Garmin GPS was used to map vegetation patches on Leonie and Anchorage Island in February 2007. Discrete patches of vegetation were walked round, and the recorded track saved. The aim of the data collection was to provide some ground truthing data for vegetation NVDI (Normalized Difference Vegetation Index) ratios calculated from satellite data. Funding: UK Natural Environment Research Council (core funding to the British Antarctic Survey).

  • The Principal Investigator in this project was Prof Ian Woodward from University of Sheffield, with 11 co-investigators at the Centre for Ecology and Hydrology (CEH), the Forestry Commission’s Forest Research, the Agriculture and the Environment Division at Rothamsted Research, and the Universities of Aberdeen, Edinburgh, Leeds, York, Oxford and Southampton.

A global map of plant functional types that exert significant impacts on the carbon cycle was also developed.

  • This dataset contains the percentage cover of plant species, bare ground and litter from twelve 1x1m vegetation monitoring plots. Plots are from two distinct vegetation communities (Herschel, Komakuk) approximately 500m apart. Plots were established in 1999 and monitored in 2004, 2009, 2013, 2014, 2015, 2016 and 2017. Data is presented as total percentage cover per species (not relative cover). Funding was provided by the NERC grant NE/M016323/1.

  • This dataset contains phenological records (timing of life events such as the opening of flowers) for tundra plant species from eight 2x2m monitoring plots. Plots are from two distinct vegetation communities (Herschel, Komakuk, coded in the data as HER and KOM). Plots were established in 2016 and monitored in 2016 and 2017. Data are presented as phenological stages for each monitored plant individual at survey dates across the 2016 and 2017 growing seasons. Flower stalk length, leaf length and new growth length were measured in mm. Active layer depth was measured in cm and was recorded at the corner of each 2x2 m plot. Soil moisture was measured as a percentage. Funding was provided by the NERC grant NE/M016323/1.

  • This dataset contains annual growth time series for 296 tundra shrubs belonging to 7 species (Salix and Betula genera) collected at the following sites in Northern Canada: Qikiqtaruk-Herschel Island (Yukon Territory), Kluane region (Yukon Territory), Umiujaq (Quebec) and Salluit (Quebec). Each individual time series (raw measurements) is presented along with the species and canopy size of the corresponding shrub. Funding was provided by the NERC grant NE/M016323/1.

  • This dataset contains records of the number of open flowers per plant species in each 2x2m plot on different survey dates. Plots are from two distinct vegetation communities (Herschel, Komakuk, coded in the data as HER and KOM). Plots were monitored in 2017. Funding was provided by the NERC grant NE/M016323/1.

  • This dataset contains plant trait measurements for nine plant functional traits (specific leaf area, vegetative height, reproductive height, seed mass, leaf dry matter content, wood density, leaf area, leaf fresh mass, leaf dry mass) collected in situ from tundra plant communities at three sites in the Yukon Territory, Canada. The three sites (Kluane Platueau (60.96 degN, 138.41 degW), Pika Camp (61.22 degN, 138.28 degW), Qikiqtaruk-Herschel Island (69.57 degN, 138.90 degW)) were visited annually from 2014-2017. Funding was provided by the NERC grant NE/M016323/1.
