The achievement of the targets of coordinated control of PM 2.5 and O 3 and the carbon
peaking and carbon neutrality depend on the development of pollution and greenhouse gas …

The performance of an all fibered near-infrared laser heterodyne radiometer (NIR-LHR) is
demonstrated in ground-based solar occultation mode. A 1× 2 fiber optical switch is …

We developed a near-infrared (NIR) dual-channel oxygen-corrected laser heterodyne
radiometer (LHR) in the ground-based solar occultation mode for measuring vertical profile …

The performance of an interband cascade laser based laser heterodyne radiometer (LHR) is
demonstrated in ground-based solar occultation mode. High-resolution (0.0033 cm^− 1) …

We present the design of a portable version of our miniaturized laser heterodyne radiometer
(mini-LHR) that simultaneously measures methane (CH 4) and carbon dioxide (CO 2) in the …

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 …

A novel, to the best of our knowledge, performance-enhanced laser heterodyne radiometer
has been developed by utilizing a semiconductor optical amplifier to amplify the collected …

In this paper, we present the design of a laser heterodyne radiometry instrument that
combines, for the first time, frequency comb calibration and a remarkably high level of …

We describe the development of a near-infrared laser heterodyne radiometer: the precision
heterodyne oxygen-corrected spectrometer (PHOCS). The prototype instrument is equipped …

High-precision observations provide an efficient way to calculate greenhouse gas emissions
from agricultural fields and their spatial and temporal distributions. Two high-resolution laser …
