About
C. A. Hostetler is a prominent atmospheric scientist at NASA Langley Research Center whose work centers on aerosol remote sensing, lidar technology, and the characterization of atmospheric particulates. He has made foundational contributions to the development and validation of airborne and spaceborne lidar systems, most notably through his extensive work with the High Spectral Resolution Lidar (HSRL) and the CALIOP instrument aboard the CALIPSO satellite. His research has systematically advanced scientists' ability to retrieve accurate vertical profiles of aerosol extinction, backscatter, and depolarization — measurements critical for understanding air quality and climate forcing. Hostetler's validation studies have been particularly impactful, earning over 120 citations each for his assessments of CALIOP aerosol extinction products and HSRL measurements during the landmark MILAGRO megacity campaign. His participation in major field campaigns — including DISCOVER-AQ, ACEPOL, TCAP, and ORACLES — reflects a career-long commitment to bridging airborne observations with satellite retrievals. His work on aerosol optical depth enhancements near polluted clouds and the relationship between columnar aerosol properties and surface-level PM2.5 has direct implications for public health monitoring. With hundreds of cumulative citations, Hostetler remains a leading figure in multi-platform aerosol measurement science.
