| Title: | Space Weather Program: Low Latitude Ionospheric Sensor Network |
| Abstract: |
Since 2007 the National Institute for Space Research starts a task force to develop and operate a Brazilian space weather program. The main purpose of the program is to monitor the space climate and weather from sun, interplanetary space, magnetosphere and ionosphere-atmosphere, and to provide useful information to space related communities, technological, industrial and academic areas. Several physical parameters of the sun-earth environment are already being monitored through a large ground base network of scientific sensors and under collaboration with other space weather centers. Most of these physical parameters are daily published on the Brazilian space weather program web site, mostly related to the low latitude ionospheric sensor network. A comprehensive data bank and an interface layer are under development to allow an easy and direct access to the useful information. Nowadays, the users will count on products derived from a GPS monitor network that covers most of the Brazilian territory; a digisonde network that monitors the ionospheric profiles in two equatorial sites and in one low latitude site; and two coherent radars that sound the E and F equatorial ionospheric region searching for plasma irregularities. In a near future, another coherent radar, three other digisondes, and several other GPS sensors are to be installed. The coherent radar should be installed in Belém-PA, close to the dip equator. The three digisondes should be installed in the western portion of Brazil under the same magnetic meridian in specific location in such a way that they will cover a south, equatorial and north latitude. New GPS sensors will be spread all over the country in order to cover blanks in the network. Contacting Author: C. M. Denardini (denardin@dae.inpe.br) |
