Measurement of aerosol optical depth and sub-visual cloud detection using the optical depth sensor (ODS)
A small and sophisticated optical depth sensor (ODS) has been designed to work in the atmosphere of Mars. The instrument measures alternatively the diffuse radiation from the sky and the attenuated direct radiation from the Sun on the surface. The principal goals of ODS are to retrieve the daily mean aerosol optical depth (AOD) and to detect very high and optically thin clouds, crucial paramete...

Reviewer #1: Synopsis: This paper provides a description of a rather innovative instrument to estimate aerosol optical depth. Readers are first reminded that this Optical Depth Sensor (ODS), was originally designed to fly on a mission to Mars. Thus, the instrument must be robust (preferably no moving parts), and must be able to account for changing calibration, such as when dust collects on win...

Author’s response: This is a reasonable suggestion. We have changed the lines 15-18 in page 9620 by: "For testing the reliability of calculations, first the radiance simulated by SHDOM code was compared against the DISORT plane-parallel radiative transfer code and using different values of the number of streams. These comparisons were carried out for a total opacity of 0.5, a single scattering ...
متن کاملAerosol Optical Depth Spatial and Temporal Variability Using Satellite Data Over Indian Major Cities
Introduction: The study’s main aim is to investigate the long-term variation of Aerosol Optical Depth (AOD). It also aims to show the relationship between meteorological parameters. This study evaluates long-term (2010 to 2021) special and temporal changes over major Indian regions using satellite-based data from NASA’s Terra Satellite. Materials and Methods: This study was carried out during ...
متن کاملObserved Covariations of Aerosol Optical Depth and Cloud Cover in Extratropical Cyclones
Using NASA Moderate Resolution Imaging Spectroradiometer aerosol optical depth and total cloud cover retrievals, CloudSat-CALIPSO cloud profiles, and a database of extratropical cyclones and frontal boundary locations, relationships between changes in aerosol optical depth and cloud cover in extratropical cyclones occurring over Northern Hemisphere oceans are examined. A reanalysis data set is ...
