Journal ArticleDOI
Aerosol classification using airborne High Spectral Resolution Lidar measurements – methodology and examples
Sharon P. Burton,Richard Ferrare,Chris A. Hostetler,J. W. Hair,R. R. Rogers,Michael D. Obland,Carolyn F. Butler,A. L. Cook,David B. Harper,Karl D. Froyd +9 more
TL;DR: In this article, a methodology based on observations of known aerosol types is used to qualitatively classify the extensive set of airborne high-spectral resolution lidar measurements into eight separate types.
Journal ArticleDOI
Observations of the spectral dependence of linear particle depolarization ratio of aerosols using NASA Langley airborne High Spectral Resolution Lidar
Sharon P. Burton,J. W. Hair,Michael Kahnert,Michael Kahnert,R. A. Ferrare,Chris A. Hostetler,A. L. Cook,David B. Harper,Timothy A. Berkoff,S. T. Seaman,S. T. Seaman,J. E. Collins,Marta A. Fenn,R. R. Rogers,R. R. Rogers +14 more
TL;DR: In this paper, the authors presented the results of three case studies from the NASA Langley airborne High Spectral Resolution Lidar-2 (HSRL-2) for three wavelengths: 355, 532, and 1064 nm.
Journal ArticleDOI
NASA LaRC airborne high spectral resolution lidar aerosol measurements during MILAGRO: observations and validation
R. R. Rogers,J. W. Hair,Chris A. Hostetler,R. A. Ferrare,Michael D. Obland,A. L. Cook,David B. Harper,Sharon P. Burton,Yohei Shinozuka,Yohei Shinozuka,Cameron S. McNaughton,Antony D. Clarke,Jens Redemann,P. B. Russell,John M. Livingston,Lawrence I. Kleinman +15 more
TL;DR: In this paper, the authors present high spatial and vertical resolution HSRL measurements of aerosol extinction and optical depth from MILAGRO and comparisons of those measurements with similar measurements from other sensors and model predictions.
Assessment of the CALIPSO Lidar 532 nm attenuated backscatter calibration using the NASA LaRC airborne High Spectral
Resolution Lidar,R. R. Rogers,Chris A. Hostetler,J. W. Hair,R. A. Ferrare,Zhaoyan Liu,David B. Harper,A. L. Cook,Kathleen A. Powell,M. Vaughan,D. M. Winker +10 more
TL;DR: In this paper, the authors present a quantitative assessment of the CALIOP 532 nm calibration (through the 532nm total attenuated backscatter) using in- ternally calibrated airborne HSRL underflight data.
Journal ArticleDOI
Comparison of mixed layer heights from airborne high spectral resolution lidar, ground-based measurements, and the WRF-Chem model during CalNex and CARES

TL;DR: In this article, a modified Haar wavelet covariance transform method was used to derive the ML heights from high spectral resolution lidar (HSRL) profiles during 31 flights, many in coordination with other research aircraft and ground sites, to study the structure of the atmospheric boundary layer.
