“…[16] The emission spectra are simulated using a line-ofsight integration of the Planck radiation source, where we account for absorption by both ozone [Rothman et al, 2005] and the water vapor continuum [Clough et al, 2000]. The spectral gridding of the model is 0.02 cm À1 , which we found to be appropriate for a line-by-line simulation in this spectral range.…”

[1] We investigate the synergistic use of ultraviolet reflectivity measurements in the spectral range of 290-320 nm and the thermal emission spectra at the 9.6-mm ozone absorption band for the retrieval of vertical distribution of tropospheric ozone from satellite observations. Retrievals of vertical ozone profiles are performed from simulated measurements for different atmospheric conditions. The retrievals show that the use of measurements of both spectral ranges can improve significantly the retrieved ozone in the lowest 5 km of the troposphere. Here largest improvements are found for tropical temperature distributions and for a low thermal contrast in the lower troposphere. So the use of both spectral bands may help to improve the remote sensing of tropospheric ozone from space.Citation: Landgraf, J., and O. P.

“…Two commonly used radiative transfer models are used for this purpose: LBLRTM v6.12 [Clough et al, 1992] and MODTRAN v4.2 [Berk et al, 2000]. Both of these models obtain line parameters from the HITRAN 2000 database and the water vapor continuum data from the CKD 2.4 model [Clough et al, 1989].…”

Downward longwave irradiance uncertainty under arctic atmospheres: Measurements and modeling

et al. 2003

View full text Add to dashboard Cite

[1] Measurement and modeling of downward longwave irradiance are a special challenge in arctic winter due to its low water vapor content and the extreme meteorological conditions. There are questions about the representativeness of the instrument calibration, the consistency and uncertainty of measurements and models in these environments. The Second International Pyrgeometer and Absolute Sky-scanning Radiometer Comparison (IPASRC-II), which was conducted at Atmospheric Radiation Measurement (ARM) program's North Slope of Alaska (NSA) site in Barrow provided a unique opportunity to compare high accuracy downward longwave irradiance measurements and radiative transfer model computations during arctic winter. Participants from 11 international institutions deployed 14 pyrgeometers, which were field-calibrated against the Absolute Sky-scanning Radiometer (ASR). Continuous measurements over a 10-day period in early

“…This particularly covers models for the micro-and millimeter-wave region (e.g., Liebe et al, 1993;Rosenkranz, 1993Rosenkranz, , 1998 but also several editions of the Clough-Kneizys-Davies continuum model (CKD; Clough et al, 1989Clough et al, , 2005, later enhanced by Mlawer and Tobin (MT_CKD;Mlawer et al, 2012), models that cover the entire millimeter to infrared spectral range. However, all of these continua have been developed with a focus on Earth observations.…”

Abstract. This article describes the latest stable release (version 2.2) of the Atmospheric Radiative Transfer Simulator (ARTS), a public domain software for radiative transfer simulations in the thermal spectral range (microwave to infrared). The main feature of this release is a planetary toolbox that allows simulations for the planets Venus, Mars, and Jupiter, in addition to Earth. This required considerable model adaptations, most notably in the area of gaseous absorption calculations. Other new features are also described, notably radio link budgets (including the effect of Faraday rotation that changes the polarization state) and the treatment of Zeeman splitting for oxygen spectral lines. The latter is relevant, for example, for the various operational microwave satellite temperature sensors of the Advanced Microwave Sounding Unit (AMSU) family.
