Evidence of refractive index variation with roughness in CLOUDSAT W-band radar and different applications of lidar/radar ocean surface echo

چکیده
Lidar and radar observations from CALIPSO and CloudSat missions have allowed the development of methods to determine atmospheric parameters [1, 2]. Total aerosol optical depth (AOD) and cloud liquid water path have thus been derived at the scale of the lidar or radar footprint using AMSR-E wind speed information [3, 4], or the combination of lidar and radar observations using ocean surface echo[5]. We present here the relationship between the wind speed retrieved by AMSR-E radiometer and the normalized scattering cross section of the radar (CPR) in cloud free regions [6]. We also discuss the potential improvement for lidar and radar calibration and the value of collocated lidar/radar ocean surface observations to study the different way to correct CLOUDSAT from water vapor attenuation.

Studies of Sea Surface Normalized Radar Cross Sections Observed by Cloudsat
The primary science instrument of the CloudSat Mission is the Cloud Profiling Radar (CPR). The CPR is a W-band (94 GHz) nadir looking radar (e.g. Tanelli, 2008) with the purpose of measuring backscattered power from hydrometeors (clouds and precipitation). Although the CPR contains an internal calibration system, external calibration using geophysical sources with known normalized radar cross-s...
متن کاملHydrometeor Detection Using Cloudsat—An Earth-Orbiting 94-GHz Cloud Radar
In late April 2006, NASA launched Cloudsat, an earth-observing satellite that uses a near-nadir-pointing millimeter-wavelength radar to probe the vertical structure of clouds and precipitation. The first step in using Cloudsat measurements is to distinguish clouds and other hydrometeors from radar noise. In this article the operational Cloudsat hydrometeor detection algorithm is described, diff...
متن کاملObservations of Wintertime U.S. West Coast Precipitating Systems with W-Band Satellite Radar and Other Spaceborne Instruments
The potential of CloudSat W-band radar for observing wintertime storms affecting the West Coast of North America is evaluated. Storms having high hydrological impact often result from landfalls of ‘‘atmospheric rivers’’ (‘‘ARs’’), which are the narrow elongated regions of water vapor transport from the tropics. CloudSat measurements are used for retrievals of rain rate R and cloud ice water pat...
متن کاملAn Analysis of Ku-Band Profiling Radar Observations of Boreal Forest
Radar sensors have the potential to retrieve vertical forest structure measurements thanks to their capability to penetrate into the foliage. However, studies are needed in order to understand better the interaction of radar beams with the canopy. The most commonly used radar technique for estimating forest parameters operates from spacecraft at different wavelength (X-, C-, and L-band). In ord...
متن کاملOcean and Polarization observations from active remote sensing: Atmospheric and Ocean science applications
In the past few years, we have demonstrated how the surface return measured by the active instruments onboard CloudSat and CALIPSO could be used to retrieve the optical depth and backscatter phase function (lidar ratio) of aerosols and ice clouds. This methodology lead to the development of a data fusion product publicly available at the ICARE archive center using the Synergized Optical Depth o...
