Summer crops (sugar beets) in the United Kingdom have beenharvested, and winter crops (winter wheat, winter barley, and rapeseed) havebeen planted. In the monitoring period, negative departures from average wererecorded for both agroclimatic and the agronomic indicators. As shown by theNDVI profiles, national NDVI values were lower than average from November to earlyJanuary, but above to average by late January. According to the crop conditionmap based on NDVI, close to 62.1% of the country recorded lower than averageNDVI from October to January, while for the remainder (37.9% of the region)crop condition was higher than average, including Norfolk, Suffolk, Yorkshire,Durham, Northumberland, Berwickshire, East Lothian, Midlothian, Fife,Kinross-shire, and Perthshire). This spatial pattern is also reflected by themaximum VCI in the different areas, with a VCIx of 0.87 for the countryoverall. At the national scale, precipitation totals were 31% below average,and temperature (TEMP, -2.3°C) and radiation (RADPAR, -1.2%) were below theaverage. Prospects for winter crops are currently unfavorable.
