Item Open Access Actualización de instrumento óptico FPI en estación óptica del ROJ(Instituto Geofísico del Perú, 2010-09) Navarro, L.; Veliz, OscarEn el presente reporte se detalla los cambios realizados al instrumento óptico Interferometro Fabry-Perot de la estación óptica del Radio Observatorio de Jicamarca (11°57'31.38"S, 76°51'36.84"W) mediante los cuales se ha incrementado su sensibilidad al doble de órdenes interferométricos de la línea OI de la luminiscencia nocturna.Item Open Access Pasado, presente y futuro de estudios de aeronomía usando FPI en Perú(Instituto Geofísico del Perú, 2010) Navarro, L.; Veliz, Oscar; Chau Chong Shing, Jorge Luis; Meriwether, J. W.Diapositivas presentadas en el XIII Encuentro Científico Internacional, (ECI 2010i), realizado del 2 al 6 de agosto de 2010 en la ciudad de Lima.Item Open Access Red de interferómetros Fabry-Perot en Perú para estudios de aeronomía(Instituto Geofísico del Perú, 2010) Navarro, L.; Meriwether, J.; Veliz, Oscar; Chau Chong Shing, Jorge LuisPresentación interna del Radio Observatorio de Jicamarca-IGP.Item Open Access Reprocessing of data from Fabry-Perot interferometers (FPI) belonging to the IGP network of optical instruments(Instituto Geofísico del Perú, 2021-06) Barbaran Meza, J.; Rojas, R.; Navarro, L.; Veliz, Oscar; De la Jara, César; Milla, MarcoIGP network of optical instruments consist of two types of imaging instrumentation: Fabry-Perot Interferometers (FPI) and All-Sky imagers (ASI). The FPI can obtain two dimensional interferograms that are used to study the dynamics of the upper atmosphere. Since the deployment of the first FPI in 1985 and up to the implementation of the FPI network in 2009, which was fully operational in 2011, a processing technique based on Fourier decomposition of the interferogram spectra has been used. An improvement of this technique has been released with a better representation and fitting scheme of the Airy function parameters needed for better estimation of the airglow neutral winds and temperatures. Given that the new processing technique has potentially the ability to generate better products, reprocessing of the IGPs optical data base is being evaluated. First, the two methods need to be compared. In this work we present an analysis of the two methods comparison, showing differences, advantages, and possible improvements to implement.Item Open Access Simultaneous measurements of thermospheric winds and ion drifts at Jicamarca and Arequipa, Peru(Instituto Geofísico del Perú, 2010) Navarro, L.; Veliz, Oscar; Chau Chong Shing, Jorge Luis; Meriwether, J. W.Ponencia presentada en el 2010 CEDAR Workshop, University of Colorado, Boulder, CO, 20-25 June 2010.
