Meteorological data collected at Welsh Short Rotation Coppice (Intensive) sites
As a result of high oil prices in the mid-1970s, many European and Scandinavian countries initiated research programmes investigating fuel production from energy crops. Initial studies were aimed at identifying suitable crop systems.
Although informative, results from early research programmes could not predict the yield of willow or poplar SRC under different environmental conditions. Without this information planners could not make informed decisions as to where SRC plantations and power generation plants should be sited in order to maximise yield and land use efficiency. Growers also needed information on likely yields achievable by different site/clone combinations, in order to estimate their financial return from these crops. For these reasons the Department of Trade and Industry (DTI), the Ministry of Agriculture, Fisheries and Food (now incorporated into the Department of the Environment, Farming and Rural Affairs [Defra]) and the Forestry Commission (FC) sought to quantify and model the yield potential of a diverse range of willow and poplar clones when grown as SRC on agricultural sites across the UK.
The subsequent research programme ‘Yield models for energy coppice of poplar and willow’ was coordinated by ETSU and carried out by Forest Research (FR) and the Department of Agriculture and Rural Development, Northern Ireland (DARDNI, formally Department of Agriculture, Northern Ireland). The backbone of this research programme was a network of 49 field trials established on agricultural land throughout England, Scotland, Wales and Northern Ireland. Data collected from these sites continues to be used in the development of empirical yield models and process based predictive yield models capable of estimating the productivity of varieties grown under a range of environmental conditions.
This data set contains the meteorological data collected at these sites during the project. The variables recorded were:
Mean air temperature (oC); Wet bulb temperature (oC); Maximum air temperature (oC); Minimum air temperature (oC); Mean soil temperature (oC); Maximum soil temperature (oC); Minimum soil temperature (oC); Rainfall (mm); Mean relative humidity (%); Surface wetness; Net solar radiation (W.m-2); Global solar radiation (W.m-2); Wind direction (o); Wind speed (ms-1)
