Rainfall and two river flows in Colombia

Description

This dataset contains daily observations of rainfall (in millimeters) and river flows (in m^3/s) for two rivers in southern Colombia. Rainfall was recorded at a meteorological station located at an altitude of 2400 meters above sea level. River flows were measured at two hydrological stations: El Trébol station, which monitors the Bedón River at an altitude of 1720 meters, and Villalosada station, which monitors the La Plata River at an altitude of 1300 meters. The stations are located near the equator, a geographic feature that helps reduce seasonal distortions and facilitates the analysis of the dynamic relationship between rainfall and river flows. The sample period spans from January 1, 2006, to April 14, 2009.
