We present the first Italian reference secular variation curves for both direction and intensity that cover the last 3000 years. Strict selection criteria were applied to guarantee the collection of the most reliable data within a 1000 km radius of Viterbo, including archaeomagnetic records from archaeological material and volcanic rocks. The new curves are calculated using Bayesian statistics and they depict interesting geomagnetic field features, such as high‐intensity periods. These are the first curves for Italy, including both directional and intensity data, and they can be used as reference curves for archaeomagnetic dating, not only in Italy but also in nearby countries.

过去3000年中新的意大利定向和强度古地磁参考曲线：对世俗变化的认识及其对测年的意义

我们介绍了过去3000年中意大利在方向和强度方面的第一条参考长期变化曲线。应用严格的选择标准以确保在维泰博（Viterbo）半径1000公里范围内收集最可靠的数据，包括来自考古材料和火山岩的古地磁记录。新曲线是使用贝叶斯统计方法计算的，它们描绘了有趣的地磁场特征，例如高强度周期。这些是意大利的第一条曲线，包括方向和强度数据，它们不仅可以在意大利而且可以在附近国家用作古地磁测年的参考曲线。
