AbstractNeste trabalho são apresentadas medidas de temperatura da Mesosfera superior no setor Brasileiro de baixas latitudes através das técnicas de Radar de Laser e Luminescência Atmosférica durante um período de dois anos. A técnica de Radar de Laser consiste essencialmente na detecção do espalhamento ressonante em dois comprimentos de onda do sódio, um no pico D_2a e outro entre os picos D_2a e D_2b, que permitem calcular os perfis de densidade e temperatura em uma faixa de altitude de 80 e 110 km. Além disso, medidas da temperatura rotacional da hidroxila através da Luminescência Atmosférica foram inferidas com dados de Fotômetro. Rotinas feitas em IDL (Interactive Data Language) e Visual Basic for Applications, facilitaram a comparação de medidas simultâneas de temperatura e possibilitou a determinação do pico de emissão do OH através do ajuste obtido pelo método de mínimos quadrados destas temperaturas durante os anos de 2007 e 2008, utilizando dados do Radar de Laser, situado em São José dos Campos (23ºS, 46º O) e do Fotômetro, situado em Cachoeira Paulista (22,7ºS, 45º O). Em geral, as temperaturas do OH foram mais altas do que as do Na. Em algumas ocasiões foram observadas oscilações na altura de emissão estimada do OH, que podem ser causadas devido a atividades de ondas de gravidade. ABSTRACT: We present temperature measurements of the upper mesosphere obtained by lidar and airglow in the low latitude Brazilian sector over a period of two years. In the 80-110 km region, free sodium atoms are abundant enough to allow probing of the Doppler broadened hyperfine structure of the D2 resonance transition by ground-based lidar. The lidar technique consists in detection of the resonance transition at two wavelengths, one at the D_2a peak, and another at the minimum between the D_2a and D_2b peaks, making it possible to calculate the density and temperature profiles. At the same time, rotational temperatures obtained from the airglow OH (6-2) emission using photometer data were determined. Given the lidar-derived temperature profile, we adjusted the height of an empirical OH emission profile so as to minimize the difference between the observed OH temperatures and the weighted lidar temperature. This procedure was carried out using lidar data from São José dos Campos (23ºS, 46ºW) and photometer data from Cachoeira Paulista (22,7ºS, 45ºW), about 100 km away. In general, the OH temperatures were higher than those derived from the lidar measurements, and it was not always possible to fine an emission profile giving good agreement between the two. On some occasions we observed oscillations in the estimated OH emission height, which we believe to be caused by gravity waves.
