背景资料：大多数研究使用分析区域或城市附近气象站的温度观测数据作为确定性-响应关联的参考点。气候再分析数据集已经被用于气候研究，但还没有被常规地用于环境epidemiology.Methods：我们比较了死亡率与温度的关系，使用气象站温度和ERA-5再分析数据的52个省会城市在西班牙，使用时间序列回归与分布滞后非线性模型。ERA-5再分析资料与气象站的气温分布形态有很好的相关性（相关系数在0.90 ~ 0.99之间）。整体累积的温度响应曲线是非常相似的形状和风险估计冷和热的影响，虽然ERA-5的风险估计略低于气象站temperature.Conclusions：再分析数据允许温度的健康影响的估计，即使在远离气象站或没有任何可用的地区。
Background: Most studies use temperature observation data from weather stations near the analyzed region or city as the reference point for the exposure-response association. Climatic reanalysis data sets have already been used for climate studies, but are not yet used routinely in environmental epidemiology.Methods: We compared the mortality-temperature association using weather station temperature and ERA-5 reanalysis data for the 52 provincial capital cities in Spain, using time-series regression with distributed lag non-linear models.Results: The shape of temperature distribution is very close between the weather station and ERA-5 reanalysis data (correlation from 0.90 to 0.99). The overall cumulative exposure-response curves are very similar in their shape and risks estimates for cold and heat effects, although risk estimates for ERA-5 were slightly lower than for weather station temperature.Conclusions: Reanalysis data allow the estimation of the health effects of temperature, even in areas located far from weather stations or without any available.
