对英国气象局 1 公里雷达得出的 8 年（2006 年至 2013 年）降水率合成数据进行了检查，以评估其是否能够准确表示英国和爱尔兰长期的年平均降水量。雷达合成数据的年平均降水量与仪表测量结果相当，英国和爱尔兰的平均误差为+23mmyr−1，英国的平均误差为+29mmyr−1(3%)，爱尔兰共和国的平均误差为–781mmyr−1(46%)。雷达得出的降水合成数据在包括北爱尔兰在内的英国上空很有用，但在爱尔兰共和国上空并不准确，特别是在南部。
The Met Office 1km radar‐derived precipitation‐rate composite over 8 years (2006–2013) is examined to evaluate whether it provides an accurate representation of annual‐average precipitation over Great Britain and Ireland over long periods of time. The annual‐average precipitation from the radar composite is comparable with gauge measurements, with an average error of +23mmyr−1over Great Britain and Ireland, +29mmyr−1(3%) over the United Kingdom and –781mmyr−1(46%) over the Republic of Ireland. The radar‐derived precipitation composite is useful over the United Kingdom including Northern Ireland, but not accurate over the Republic of Ireland, particularly in the south.
