- Abstract
Stable isotopes monitoring of rainfall in México has been limited. This study presents the characterization of the isotopic composition (δ18O, δ2H, Excess-d) of meteoric water that occurred in the Querétaro Valley from September 2017 to July 2021. Laser water isotope analyzers Picarro L2110-i and Los Gatos Research LWIA-45EP were used to carry out the stable isotope analyses. The local meteoric water line was obtain using a least squares regression of the isotope data, δ2H = 7.65 δ18O + 6.97. This Line has a slope and an intercept lower than the World Meteoric Line (LMM). The data show that the Local Meteoric Line has a lower slope and intercept than the LMM, due to secondary evaporation of small rainfall (< 30 mm per month). This collector forms part of the National Network for Monitoring the Isotope Composition of Rain that the Mexican Institute of Water Technology installed in various physiographic provinces of the country.
