“…A NH 3 sensor based on this method was found to be 140 times less sensitive to N 2 O contaminant gas, even though the spectral absorption of N 2 O is significantly stronger than the spectral absorption of NH 3 in the band used. Taylor et al (1972) provide details of a similar system, intended to measure remotely (from a satellite) the temperature of the upper atmosphere from the spectral transmission of CO 2 .Th e system gathered light reflected from the earths atmosphere, and passed it though a pressure Fig. 6.…”

“…In this study, the cell length and temperature are same for each channel and every SSU sensors [Television and Infrared Observation Satellite (TIROS)-N, NOAA-6, NOAA-7, NOAA-8, NOAA-9, NOAA-11, and NOAA-14], taken as 1 cm and 302.6 K, respectively. The weighting function peak height for a CO 2 PMR (Taylor et al 1972) may be analytically expressed as The uncertainty on these three parameters induces an effect of less than 0.01% on BT changes (Brindley et al 1999), and can be negligible compared to the impact of the cell pressure changes, which can be on an order of 1 K. The assessment of the effects of the cell drifts upon measured BTs is discussed in section 5.…”

To better use the Stratospheric Sounding Unit (SSU) data for reanalysis and climate studies, issues associated with the fast radiative transfer (RT) model for SSU have recently been revisited and the results have been implemented into the Community Radiative Transfer Model version 2. This study revealed that the spectral resolution for the sensor's spectral response functions (SRFs) calculations is very important, especially for channel 3. A low spectral resolution SRF results, on average, in 0.6-K brightness temperature (BT) errors for that channel. The variations of the SRFs due to the CO 2 cell pressure variations have been taken into account. The atmospheric transmittance coefficients of the fast RT model for the Television and Infrared Observation Satellite (TIROS)-N, NOAA-6, NOAA-7, NOAA-8, NOAA-9, NOAA-11, and NOAA-14 have been generated with CO 2 and O 3 as variable gases. It is shown that the BT difference between the fast RT model and line-by-line model is less than 0.1 K, but the fast RT model is at least two orders of magnitude faster. The SSU measurements agree well with the simulations that are based on the atmospheric profiles from the Earth Observing System Aura Microwave Limb Sounding product and the Sounding of the Atmosphere using Broadband Emission Radiometry on the Thermosphere Ionosphere Mesosphere Energetics and Dynamics satellite. The impact of the CO 2 cell pressures shift for SSU has been evaluated by using the Committee on Space Research (COSPAR) International Reference Atmosphere (CIRA) model profiles. It is shown that the impacts can be on an order of 1 K, especially for SSU NOAA-7 channel 2. There are large brightness temperature gaps between observation and model simulation using the available cell pressures for NOAA-7 channel 2 after June 1983. Linear fittings of this channel's cell pressures based on previous cell leaking behaviors have been studied, and results show that the new cell pressures are reasonable. The improved SSU fast model can be applied for reanalysis of the observations. It can also be used to address two important corrections in deriving trends from SSU measurements: CO 2 cell leaking correction and atmospheric CO 2 concentration correction.

“…These bands have been used, for example by Walshaw (1960) and Vigroux (1969) for the determination of the vertical distribution of 0 3 and for satellite vertical temperature distributions from CO e (see e.g. Taylor et al, 1972;Abel et al, 1970;Houghton and Smith, 1970). Williamson and Houghton (1966) have described balloon measurements of the 6.3/~ HeO emission band~ Rotational emission from H20 is important in the 18# region.…”

The techniques of studying the IR airglow are briefly discussed followed by a review of recent observations. The main emphasis is on the molecular emissions of OH and 02 from the mesosphere and lower thermosphere with a shorter discussion of the F-region atomic emissions. The theoretical interpretations of these emissions are reviewed. It is concluded that dynamic effects must play a dominant and as yet incompletely understood part in the photochemistry of the molecular emission region. An atlas of recently available airglow spectra is included.
