TL;DR: An extension of the analysis at high latitudes using ground-based observations of δD¯ and a model study shows that dynamic processes can entirely compensate for temperature effects on the isotopic composition of precipitation.

TL;DR: In this paper, an empirical solar spectrum covering the 700 to 4430 cm −1 spectral range has been constructed from an average of 224,782 individual ACE-FTS solar spectra.

TL;DR: In this article, the first aircraft calibration campaign of five European TCCON sites and a mobile Fourier Transform Spectrometer (FTS) instrument was introduced, and the results of the campaign show that the FTS mea- surements are consistently biased 1.1 %± 0.2 % low with re- spect to WMO standards.

TL;DR: In this article, the authors describe the statistical analysis of annual trends in long term datasets of greenhouse gas measurements taken over ten or more years, and employ a bootstrap resampling method to determine both the longterm and intra-annual variability of the datasets, together with the uncertainties on the trend values.

TL;DR: The Atmospheric Chemistry Experiment (ACE) mission was launched in August 2003 to sound the atmosphere by solar occultation, and the ACE-Fourier Transform Spectrometer (ACE-FTS) as discussed by the authors performs measurements in both the CO 1-0 and 2-0 rovibrational bands, from which vertically resolved CO concentration profiles are retrieved, from the mid-troposphere to the thermosphere.
