Variations of mean winds and solar tides in the mesosphere and lower thermosphere over time scales ranging from 6 months to 11 yr: Saskatoon, 52°N, 107°W

Journal of Atmospheric and Terrestrial Physics, 1994
Abstract The MF radar (spaced antenna) winds technique has been used to measure mean winds at Saskatoon (52°N, 107°W), Canada for over a solar cycle. The data from 1974 to 1991 are used to study different periods of oscillation such as 24-, 12-, 6- and 3-month oscillation etc.

Modes of Daily Mean Thermospheric ΣO/N₂ Variability Over a Solar Cycle Observed by TIMED/GUVI

Journal of Geophysical Research: Space Physics
AbstractThe relative column abundance of monatomic oxygen to molecular nitrogen (ΣO/N2) in the lower thermosphere has been measured for over two decades by TIMED/GUVI. This data set provides an opportunity to assess how well current empirical thermosphere climatologies reproduce observed composition variations on timescales of days to a solar cycle ...

Time Series of Daily Mean Solar Irradiance over South America: Some Results of 11 Years of CPTEC GL Model Using GOES Imagery

AIP Conference Proceedings, 2009
Distribution of solar radiation over South America is daily assessed by the CPTEC’s GL1.2 model using GOES satellite imagery (VIS channel). A time series of 11 years, January 1996 to Dezember 2006 is now available and may be used for climatological, agricultural and energy‐source studies in the scale of 1 day, 0.04°.
