Paper Abstract

Recent theoretical studies have demonstrated the potential of spaceborne high spectral resolution O2 A-band spectrometers for retrieval of aerosol and cloud optical properties. High spectral resolution is the key to these retrievals because it permits a separation of the surface and atmospheric scattering components of the reflectance measurements. Although promising, this new approach poses numerous technical challenges related to instrument design, characterization, and calibration that have not been fully addressed by previous conceptual studies. To experimentally assess the capabilities of this promising new remote sensing application, the NASA Langley Research Center has developed the Langley Airborne A-Band Spectrometer (LAABS). This instrument will serve as a unique test bed to evaluate the impact of realistic instrument performance on A-band retrieval capabilities. After full characterization of the instrument through laboratory testing, a detailed forward model of the instrument's radiance measurements will be developed. The instrument model will be validated against actual measured spectra obtained from ground-based operations of the instrument. Airborne A-band spectra obtained during initial test flights of this instrument during the CLAMS field campaign in July 2001 will be analyzed to assess aerosol retrieval capability.
