This folder contains data and reports from the ELUM project - Ecosystem Land Use Modelling and Soil Carbon Flux Trial. ELUM was funded and commissioned by the Energy Technologies Institute (the ETI) and carried out by the Centre for Ecology and Hydrology (CEH), the University of Aberdeen, the University of Southampton, Forest Research, Aberystwyth University, the University of Edinburgh and the University of York. The ELUM project aims were to provide greater understanding on the GHG and soil carbon changes arising as a result of direct land-use change (dLUC) from arable, grass and forested land to bioenergy crops, with a primary focus on the second-generation bioenergy crops Miscanthus, short rotation coppice (SRC) willow and short rotation forestry (SRF). Experimental fieldwork on Miscanthus, SRC Willow, and SRF, and adjacent control sites, was conducted at locations across the length and breadth of mainland GB to capture data across both temporal and spatial scales. 70 field sites were visited on a one-off basis to give high spatial resolution soil carbon data. These data are in folder chronosequence_soils_data. 4 network field sites spread across the UK where visited routinely and were instrumented to give high-resolution temporal greenhouse gases (GHG) data. These data are in folder network_site_data. Folder contents: ELUM_ETI_Open_Licence.txt = The licence conditions for using ELUM data and reports. chronosequence_soils_data = FOLDER: soils data, data description and README. network_site_data = FOLDER: network sites greenhouse gases (GHG) data, data description and README. reports = FOLDER: Reports from the ELUM project, including the Executive Summary report.
