Sin embargo, en su empleo es necesario tener cuidado con los datos usados para su cálculo, ya que este índice puede ser sensible tanto a la ubicación temporal de los datos como a la longitud de los registros. Así, el objetivo consistió en un reanálisis del índice de concentración de la precipitación diaria (CI) en la cuenca del Río Grande de Morelia para determinar cómo afecta la ubicación temporal de los datos y la longitud de los registros a los valores del CI, además de analizar bajo tres condiciones diferentes el comportamiento del CI en dicha cuenca. Los resultados muestran que la ubicación temporal de los registros puede afectar el valor del CI aumentándolo si se analizan los últimos años disponibles o disminuyéndolo si se toman registros anteriores a 1980. En cuanto a la longitud de los registros, se encontró que el valor de este índice tiende a estabilizarse en la mayor parte de los casos estudiados para longitudes de registros mayores a 20 años. El comportamiento anual del CI está dentro de lo reportado en la literatura; por década y para el periodo de 30 años se observó una disminución en su variabilidad. Así, se recomienda que en estudios de este tipo se elija para los análisis un periodo de registros común y de longitud acorde con los objetivos perseguidos.]]></p></abstract>

However, it is necessary to be careful with the data used for its calculation since this index can be sensitive to both the temporal location of the data and the length of the records. Thus, the objective of this work consisted of a re-analysis of the daily precipitation concentration index (CI) in the Río Grande de Morelia basin to determine how the temporal location of the data and the length of the records affect the CI values. In addition to analyzing the behavior of the CI under three different conditions. The results show that the temporary location of the records can affect the value of the CI, increasing it if the last available years are analyzed or decreasing it if records before 1980 are taken. Regarding the length of the records, it was found that the value of this index tends to stabilize in most of the cases studied for record lengths greater than 20 years. The behavior of the CI at the annual level is within that reported in the literature, and at the decade level and for the 30-year, a decrease in its variability was observed. Therefore, it is recommended that in studies of this type, a common recording period be chosen for the analyzes and a length according to the objectives pursued.]]></p></abstract>
