The conifer tree rings and spatial climate information allow reconstructing climate in areas with scarce observed data.
Dendroclimatic reconstructions in agricultural basins lacking streamflow data such as the Mayo river basin (MRB) in Northern, Mexico, are important to analyze the interannual and multiannual climatic variability and streamflow volumes used for agricultural purposes. The objective of this study was to develop a dendroclimatic reconstruction of precipitation and temperature in MRB and to determine the high and low-frequency variability of climate in the region. Dendrochronological series for the study area were downloaded from The International Tree-Ring Data Bank and associated with precipitation and temperature records generated with the North American Land Data Assimilation System v002. The reconstructed model for the analyzed variables were generated for the subperiods with the highest correlation values. High-frequency events were identified with a Density Spectral Analysis. Mann–Kendall and Pettitt tests were used to determine significant trends in the reconstructed time series. In addition, an association between the regional chronology and Standardized Evapotranspiration–Precipitation Index was determined. Time series of precipitation and temperature were reconstructed for the period 1750–2019, highlighting 30 and 28 wet and dry episodes, respectively. We found a significant (
