Is there an influence of short-term solar activity variations on mesopause region airglow?
(Elsevier, 2007-12)
A-priori, rapid variations of solar activity that directly impact on the terrestrial environment should be expected to influence airglow brightness in the mesopause region via the photodissociative production of atomic ...
Vertical propagation of gravity waves determined from zenith observations of airglow
(Elsevier, 2001-12)
From our growing data base of OH and 02 airglow intensity and temperature measurements at lower midlatitudes, gravity wave information has been extracted by time series spectral analysis. According to existing theories, ...
Statistical properties of nonlinear wave signatures in OH and O2 airglow brightness data observed at lower midlatitudes
(Elsevier, 2010-04)
Among 2187 nights of airglow observations of the OH(6-2) and O2b(0-1) bands from Argentina (mainly from El Leoncito, 32°S 69°W), 132 show airglow brightness jumps (ABJs) of short duration (16 min median). ABJs are supposed ...
Evidence of change after 2001 in the seasonal behaviour of the mesopause region from airglow data at El Leoncito
(Elsevier, 2009-12)
Airglow intensities and rotational temperatures of the OH(6-2) and O2b(0-1) bands acquired at El Leoncito (32°S, 69°W) provide good annual coverage in 1998–2002, 2006, and 2007, with between 192 and 311 nights of observation ...
Searching for trends in mesopause region airglow intensities and temperatures at El Leoncito
(Elsevier, 2002-12)
Using our large data base from the Argentine site at El Leoncito that covers the years from August 1997 to May 2001, and four individual campaigns in 1986, 1987, and 1992, we search for trends in temperatures corresponding ...
Detection of meteor radar wind signatures related to strong short-duration day-to-day airglow transitions at sites 2600 km apart
(Elsevier, 2005-12)
Bursts of strong day-to-day variations in airglow brightness and temperature for the mesopause region that last one or a few nights have frequently been observed at El Leoncito (LEO; 31.81S 69.21W), since 1997. After the ...
Mid-latitude plasma and electric field measurements during space weather month, September 1999
(Elsevier, 2003-07)
Using data collected during the September 1999 combined ionospheric campaign (CIC), we examine the effects of moderate geomagnetic activity on low and mid-latitudes. Perturbations in the zonal electric field, measured at ...
The semidiurnal tide for individual nights derived consistently from O 2 and OH intensities and temperatures
(Elsevier, 2019-05)
The semidiurnal tide is studied with 159 special cases from the large airglow database acquired at El Leoncito (31.8ºS, 69.3ºW). These cases correspond to nights which exhibit similar periods in the temperature and intensity ...
