The paper presents a review of the far‐infrared (FIR) properties of the Earth's atmosphere
and their role in climate. These properties have been relatively poorly understood, and it is …

The chemical composition of the earth's atmosphere has been an area of general research
interest for many decades. 1 However, increased attention to a number of environmental …

The Middle Atmosphere High Resolution Spectrograph Investigation (MAHRSI) was
developed specifically to measure the vertical density profiles of hydroxyl (OH) and nitric …

We report simultaneous measurements of the stratospheric concentration profiles of OH,
HO2, H2O2, H2O, O3, HNO3, NO2, N2O, HCl, HOCl, and ClO during a midlatitude balloon …

We have measured pressure broadening of the 118.455 cm− 1 (3.551 THz) F 1, 7 2+← F 1,
5 2− rotational lines of OH by H 2, He, N 2, and O 2. The measurements were made using …

Infrared spectroscopy has been traditionally carried out mainly in absorption. The virtues of
infrared emission spectroscopy have been largely overlooked, but there has been a recent …

First remote measurements of stratospheric OH with an airborne vertical sounding far-
infrared (FIR) heterodyne spectrometer are reported: Thermal emission from rotational …

The interpretation of recent odd hydrogen measurements in the stratosphere from balloons
and in the mesosphere from space indicates a serious lack of understanding in atmospheric …

The field of atmospheric chemistry is data-limited, primarily because of the challenge of
measuring the key chemical constituents in the global environment. Several recent …

The investigation of changes in ozone concentration and of the increase of the greenhouse
effect requires simultaneous and global observations of atmospheric trace species …
