Simonich Ciencias de la Tierra airglow aeronomy Upper atmosphere atmospheric dynamics atmospheric chemistry Upper atmosphere research at the Instituto Nacional de Pesquisas Espaciais of Brazil is concentrated in the areas of photochemistryand dynamics of the mesopause and lower thermosphere, middle atmosphere climatology, and stratospheric aerosols.The main emphasis is on mesopause region dynamics. Experimental studies are carried out by lidar, airglow, meteor radar androcket-borne techniques. A lidar at São José dos Campos (23° S, 46° W) measures the vertical distribution of atmospheric sodiumbetween 80 and 110 km, the atmospheric density profile, from 35 to 70 km, and stratospheric aerosols around 20 km. Airglowphotometers at Cachoeira Paulista (23° S, 45°W) and São João do Cariri (7° S, 37° W) measure emissions from atomic andmolecular oxygen, hydroxyl and sodium. Temperature in the 75-95 km region is determined from the rotational spectrum of OHand O2. An imaging system measures the horizontal structure of the same emissions in São João do Cariri. These observations areaimed mainly at studying the propagation of internal gravity waves and their effects on the atmosphere in the mesopause region.A meteor radar at Cachoeira Paulista is used to determine wind structure between 80 and 110 km on a 24-hour basis, with the mainpurpose of studying atmospheric tides and planetary waves. Occasional rocket experiments launched from Natal (6° S, 35° W) orAlcântara (2° S, 44.5° W) are used to study the vertical distribution of airglow emissions and their relationship with other atmosphericparameters. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843102 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.43 |
