Paper Abstract

Validated models describing on-orbit performance of Earth sensing instruments provide understanding of the calibration of the instrument and insight that can be used to guide design choices for future missions. The success of the Cloud Aerosol Lidar with Orthogonal Polarization (CALIOP) launched as part of the CALIPSO instrument suite provides an opportunity to develop validated radiometric and integrated models of the instrument. We present validation of these models with on-orbit data and describe how these models can be used to help define instrument requirements for future active sensing missions that hope to capture both atmospheric and oceanographic properties. While designed for atmospheric returns, CALIOP data includes backscatter from land, ice, and ocean surface and from beneath the ocean surface. A radiometric model describing atmospheric returns that has been validated against CALIOP performance is extended to include ocean subsurface returns. The model output is compared with CALIOP, aircraft lidar measurements, and space-based ocean color measurements. This provides an opportunity to explore the value of space-based lidar measurements to ocean measurements and to identify the impact of laser and detector design choices on the returned lidar signal from the ocean as part of an ongoing effort to investigate oceanographic lidars.
