Electrostatic field measurements taken in Bogotá, Colombia, during thunderstorms in November (the rainy season due to inter-tropical confluence zone over central Colombia) were used to study the performance of an isolated electric field sensor and analyse its most important operational characteristics. The distances from each flash to the studied sensor were obtained by using the Colombian lightning location system. The ΔE cf distance ratio led to defining a charge model which could be used as a reference for calibrating other electrostatic field sensors to be used as lightning warning systems.
Medidas de campo electrostático realizadas en Bogotá durante episodios de tormenta en noviembre de 2010 (típicamente temporada de lluvias dada por el paso de la zona de confluencia intertropical por el centro de Colombia) fueron usadas para estudiar y analizar las características operacionales más importantes de un sensor de campo electrostático aislado. Las distancias de cada descarga nube-tierra con respecto al sensor obtuvieron a partir de los datos suministrados por el SID (Sistema de Información de Descargas). Los ΔE en función de la distancia permitieron definir un modelo de carga puede ser utilizado como sistema de referencia para la calibración de otros sensores de campo electrostático a ser implementados en sistemas de alerta de tormentas eléctricas.
