FLORES, Weidi; ACUNA, Delia; CALLE, Victoria  and  GARCIA, Jerónimo. Probabilities of occurrence of atmospheric electric discharges for the Mantaro river basin - Peru, using goes satellite infrared and water vapor bands. Ecol. apl. [online]. 2021, vol.20, n.1, pp.53-63. ISSN 1726-2216.

Statistical summaries were found in order to calculate likelihood of lighting occurrence. They were based on the difference of bright temperature from the water vapor band and satellite's infrared GOES, and location lightning data from STARNET for countrymen communications of Marcapomacocha (4 479 meters above sea level) and Huayao (3 350 meters above sea level) located in the basin of Mantaro, from the highlands of central Peru. The usage of statistical summaries in algorithms let monitor the cloud systems that offer defined characteristics to electrical atmospheric discharge occurrence. The results of this innovative technique proved that doing the correct setting adjustments on the precision of lightning detection, optimal results can be reached using more data from both detection systems. Besides, adding a monitor system of electrical atmospheric discharge occurrence could contribute with relevant information to respond to these extreme meteorological events being useful for the economic activities in the country.
