We describe the approach to estimating the atmospheric carbon dioxide (CO 2) for the
Aerosol and Carbon Detection Lidar (ACDL) onboard the Atmospheric Environment …

The increase in atmospheric greenhouse gas concentrations of CO2 and CH4, due to
human activities, is the main driver of the observed increase in surface temperature by more …

We have developed a portable near-infrared laser heterodyne radiometer (LHR) for quasi-
simultaneous measurements of atmospheric carbon dioxide (CO_2), methane (CH_4), water …

Nitrous oxide (N 2 O) and methane (CH 4) are two important greenhouse gases in the
atmosphere. In 2019, mid-infrared (MIR) solar absorption spectra were recorded by a Bruker …

Carbon dioxide (CO2) is the most important long-lived greenhouse gas and can be retrieved
using solar absorption spectra recorded by a ground-based Fourier-transform infrared …

We analyzed the vertical distribution of atmospheric methane (CH 4) retrieved from
measurements by ground-based Fourier Transform Spectrometer (FTS) instrument in …

Results obtained from ground-based high spectral resolution measurements of solar IR
radiation absorption spectra are analyzed. These measurements have been carried out in …

AirCore samplers have been increasingly used to capture vertical profiles of trace gases
reaching from the ground up to about 30 km, in order to validate remote sensing instruments …

Ground-based high-spectral-resolution infrared measurements are an efficient way to obtain
accurate tropospheric abundances of different gaseous species, in particular greenhouse …

The laser heterodyne radiometer (LHR) has the advantages of miniaturization, low cost, and
high spectral-resolution as a ground-verification instrument for satellite observation of …
