Comparedwith the thirteen-year average, temperature (TEMP) over the reporting periodwas above average. Although radiation (RADPAR) and total precipitation (RAIN)were below average, this higher temperature still results in above averageBIOMSS. According to HGCA, 55% of the winter wheat area, all of the winterbarley area, 40% of the spring barley area, 60% of the oat area, and 99% of thewinter oilseed rape area have been harvested. The CropWatch agroclimaticindices indicate generally favorable condition at the national scale betweenApril and July in 2014, which is confirmed by the BIOMSS increase of 2% and theVCIx of 0.91. This is also consistent with the NDVI profile, which shows thatthe national NDVI average is well above the recent five-year average and closeto the five-year maximum value. According to the NDVI clusters, the NDVI valuesacross the country are above average, with the exception of the southeast andnorthern regions (Edinburgh, West Lothian, Falkirk, Dumfries and Galloway,Fife, Cambridgeshire, Suffolk and Kent), where NDVI values are below average inApril (covering approximately 16.4% of thenational territory),and the central and southern regions (South Yorkshire, Gloucestershire andWorcestershire), where NDVI values are below average in May (coveringapproximately 11.1% of the national territory).These findings are confirmedby the VCIx map. In general, the outcome of the winter crops was good; theoutlook for summer crops is average.
