The carbon cycle describes the flow of carbon, typically in the form of carbon dioxide, between the atmosphere, oceans and land. It is influenced by changes in the sources and sinks of carbon: from anthropogenic releases (fossil fuel burning), changes in land use, the respiration and photosynthesis of plants, and the uptake and release by oceans. Atmospheric measurements of carbon dioxide are...

The Canada/France WIND Imaging Interferometer (WINDII) made measurements from NASA’s Upper Atmosphere Research Satellite from 1991 to 2003. The observations were of upper atmospheric winds in the altitude range 80 to 300 km from Doppler shifts of the visible region emissions from a number of species. Altogether the atomic oxygen O(1S) 557.7 nm and O(1D) 630.0 nm emissions along with lines in...

As part of a new research program dedicated to understanding atmospheric composition, we have initiated measurements of marine boundary layer trace gases using the technique of Open-Path Fourier Transform Infrared Spectroscopy (OP-FTIR) deployed in monostatic mode (collocated source and detector) in 2015. The recently acquired system significantly expands the measurement capability of...

The High Arctic experiences prolonged periods of total darkness in the winter and continuous daylight in the summer, influencing the atmosphere and its composition in ways that are still not fully understood. Conducting atmospheric measurements in this remote region is challenging, particularly during polar night when solar-viewing instruments are not operational. By using infrared emission...

Manifestations of thermospheric dynamics have been observed in the variations of the upper atmosphere density, temperature, neutral winds and F-region plasma over a wide time range. These fields are influenced by perturbations propagating vertically from the lower and middle atmosphere (e.g. tides) and from above through variations in the solar and geomagnetic activity. The Wind Imaging...

CHAMP (CHAllenging Minisatellite Payload), a low Earth orbit minisatellite launched by the German Space Agency (DLR), was operated between July 2000 and September 2010. Its primary mission was to provide high accuracy measurements of Earth gravity and magnetic fields, but it was also equipped with other instruments to monitor its near ionospheric environment, including a large area planar...
