Seria factible ligar (correlacion) esta serie temporal con una serie generada en GEE basada en el area clasificada como "agua", de los datos Global Surface Water (GSW) y Water Occurrence, de Landsat:
Global Surface Water Explorer (web application). Has many ways to access and download data, including via GEE. And this: "The full global surface water datasets can be downloaded by using this Python script. The zip file contains the Python script and a set of instructions for using it."
Igual con el Xolotlan, con series temporales mas de altimetria mas limitadas?!
