This paper presents the parameters characterization of the electric field signatures produced by the first (FRS) and subsequent return strokes (SRS) of 12 positive cloud-to-ground flashes observed in Bogota-Colombia. These signatures were obtained from a single thunderstorm day during the measurement campaign October-November 2018. First, the features of the electric field measuring system and its geographical location are presented. Later, the characterization of the magnitude and temporal parameters was performed. The peak value of the electric field, the slow front amplitude relative-to-peak and the overshoot amplitude relative-to-peak were selected as the magnitude parameters. On the other hand, temporal parameters such as the slow front duration, the fast transition duration, the zero-to-peak rise-time, the 10-to-90% rise-time and the zero-crossing time were analyzed.
