Unlocking weather observations at Puerto Madryn-Patagonia, Argentina, 1902–1915
Abstract: 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...

CLIMATOLOGIA CONTROL DE CALIDAD DATOS TEMPERATURA AMBIENTAL HUMEDAD PRESION Abstract: 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. 2024-05-07T14:17:47Z 2024-05-07T14:17:47Z 2024 Artículo Lakkis, S.G.; Canziani, P.O.; Yuchechen, A.E.

Abstract: 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. |
