摘要

本文介绍了 1902-1915 年间马德林港最高、最低和平均气温、气压和相对湿度测量的早期记录恢复情况。利用内部一致性、容差性和时间一致性测试对数据质量进行了仔细评估。根据每日原始数据构建的所有变量的月平均序列经过了多次同质性测试,仅在气压和相对湿度方面发现了不连续性。同质化后的月平均序列与二十世纪再分析序列在年度和季节时间步长上进行了比较。此外,还使用 Mann-Kendall 程序评估了各变量的变化趋势,并研究了相对湿度与其他变量之间的相关性。结果表明,温度测量值与再分析值之间的一致性非常好,斯皮尔曼相关系数为 0.94。最低气温和最高气温的原始数据为观测数据和再分析数据的平均气温值提供了很好的上下限。相对湿度和气压的一致性较低,相关系数均接近 0.6。没有发现这些变量的变化趋势。湿度测量值与其他变量的相关性分析表明,湿度与温度呈反比关系,而与气压值没有关系。

Unlocking Weather Observations at Puerto Madryn-Patagonia, Argentina, 1902–1915
The recovery of early records of maximum, minimum, and mean temperatures; pressure; and relative humidity measurements in Puerto Madryn for the period 1902–1915 is presented. A careful evaluation of the quality of the data was performed using internal coherence, tolerance, and temporal consistency tests. The monthly mean series of all the variables, constructed from daily raw data, were subject to several homogeneity tests, and only discontinuities in pressure and relative humidity were found. The homogenized monthly mean series were compared with the Twentieth Century Reanalysis series in annual and seasonal time steps. In addition, the trends of each variable were assessed using the Mann–Kendall procedure, and correlations between relative humidity and the other variables were examined. The results show a remarkably good agreement between the temperature measurements and reanalysis values with a Spearman correlation coefficient of 0.94. The raw data for minimum and maximum temperatures represent a very good upper and lower bound for the mean temperature values of both observational and reanalysis data. Agreement was found to be lower for relative humidity and pressure with the correlation coefficients being close to 0.6 in both cases. No trends were found for the variables. The correlation analysis of the humidity measurements with the other variables shows an inverse dependence of the temperatures and no relatedness with the pressure values.
