Résumé :

When retrieving Aerosol Optical Depth (AOD) from passive satellite sensors, the vertical distribution of aerosols usually needs to be assumed, potentially causing uncertainties in the retrievals. In this study, we use the Moderate Resolution Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) sensors as examples to investigate the impact of aerosol vertical distribution on AOD retrievals. A series of sensitivity experiments was conducted using radiative transfer models with different aerosol profiles and surface conditions. Assuming a 0.2 AOD, we found that the AOD

Résumé :

Abstract. The theoretical basis of the Ozone Mapping and Profiler Suite (OMPS) Limb Profiler (LP) Version 1 aerosol extinction retrieval algorithm is presented. The algorithm uses an assumed bimodal lognormal aerosol size distribution to retrieve aerosol extinction profiles at 675 nm from OMPS LP radiance measurements. A first-guess aerosol extinction profile is updated by iteration using the Chahine nonlinear relaxation method, based on comparisons between the measured radiance profile at 675 nm and the radiance profile calculated by the Gauss–Seidel limb-scattering (GSLS) radiative transfer

Résumé :

In the Multi-Axis Differential Absorption Spectroscopy (MAX-DOAS) trace gas and aerosol profile inversion algorithm, the vertical resolution and the observation information obtained through a series of continuous observations with multiple elevation angles (EAs) can affect the accuracy of an aerosol profile, thus further affecting the results of the gas profile. Therefore, this study examined the effect of the vertical resolution of an aerosol profile and EAs on the NO2 profile retrieval by combining simulations and measurements. Aerosol profiles were retrieved from MAX-DOAS observations and c

Résumé :

Backscatter and polarization lidars have already been used extensively to investigate ice clouds (see chapters 2 and 10). A severe limitation is that trustworthy values of the volume-scattering coefficient, one of the most important parameters in the description of the impact of cirrus on climate, cannot be derived from data taken with these lidars. Even the retrieved cirrus backscatter-coefficient profile is often questionable. A discussion of achievements and limitations of the lidar method can be found in the literature (e.g., Fernald et al. 1972; Klett 1981; Fernald 1984; Klett 1985; Sasan

Résumé :

This paper deals with the problem of estimating the optical properties of aerosols based on a finite number of extinction measurements. This kind of problem arises in many situations involving the remote sensing of aerosols with optical instrumentation such as radiometers for extinction measurements and lidar systems for backscattering measurements. A technique has been developed so that extinction measurements at a finite number of spectral regions can be inverted directly to yield either extinction or backscattering values at other wavelength regions without solving for the aerosol size dist

NOAA/NESDIS is producing on an experimental basis global data sets of total aerosol optical depth over oceans.

Effectively, the retrieval algorithm correlates aerosol optical thickness with the radiance from the upwelling Channel 1 (0.58-0.68 μm) as described by Rao et al.1 and Griggs and Stowe2. Regions containing clouds have been filtered out in the aerosol retrieval algorithm.

Résumé :

In July, 1989, the Goddard Space Flight Center mobile stratospheric lidar was deployed at JPL's Table Mountain Facility in the San Gabriel Mountains east of Los Angeles (34.4N, 117.7W). The purpose was a major intercomparison of ozone sensors in order to validate the lidar technique as a reliable, accurate and precise instrument for the measurement of stratospheric ozone. The GSFC lidar data have also been used to extract a temperature profile between 30 and 65 km. The temperature retrieval utilizes the ozone profile reference wavelength (355 nm) which is essentially no absorption due to ozone
