1. Maré lunar observada com radar meteórico em três latitudes no Brasil / Lunar tide observed with meteor radar at three latitudes in Brazil
Using meteor radar data from three Brazilian sites [São João do Cariri (7.4° S ; 36.5° W), Cachoeira Paulista (22.7° S; 45.0° W) and Santa Maria (29.7° S; 53.8° W)], the atmospheric semidiurnal lunar tide in the mesosphere and lower thermosphere was studied from January 2005 to December 2008. Monthly tidal amplitudes and phases were determined using

2. Maré lunar observada com radar meteórico em três latitudes no Brasil / Lunar tide observed with meteor radar at three latitudes in Brazil
Usando dados de radares meteóricos de três localidades brasileiras [São João do Cariri (7,4° S ; 36,5° W), Cachoeira Paulista (22,7° S; 45, 0° W) e Santa Maria (29,7° S; 53, 8° W)] foi possível estudar a maré lunar atmosférica semidiurna na região da mesosfera e baixa termosfera para o período de janeiro de 2005 a dezembro de 2008. Para determ

3. Can ozone depletion and global warming interact to produce rapid climate change?
The atmosphere displays modes of variability whose structures exhibit a strong longitudinally symmetric (annular) component that extends from the surface to the stratosphere in middle and high latitudes of both hemispheres. In the past 30 years, these modes have exhibited trends that seem larger than their natural background variability, and may be related t
