The High Spectral Resolution Lidar (HSRL) for Aerosols Winds and Clouds using the Optical Autocovariance Wind Lidar (HAWC-OAWL) is designed to provide co-located and simultaneous measurements of wind and aerosol properties with a focus on the study of how aerosols and winds affect cloud radiative forcing. Under this IIP, Ball Aerospace will enhance the OAWL system science measurements in the following ways: provide additional aerosol characterization information by adding 1064 nm wavelength backscatter and depolarization to the existing 532 nm and 355 nm channels; enable retrievals of horizontal wind speed and direction profiles by integrating two high TRL-telescopes with perpendicular line-of-sight (LOS) perspectives on the wind fields; increase data coverage by adding a wavelength/polarization multiplexing system to make measurements along the two LOS perspectives, simultaneously, with one wavelength per view; increase TRL and improve data precision and throughput through the design and build of low-noise detector electronics and a robust path-to-space data acquisition system with real-time processing of wind and aerosol products; and package and qualify the system for ground and for flexible NASA aircraft operation with frame and housing that provide structural and thermal independence from widely varying aircraft environments. The system will be validated in a co-located ground-based validation of the HAWC-OAWL system against an existing HSRL after which we will work with the HAWC science team to demonstrate the impact that combined wind/aerosol data products can have on future atmospheric science campaigns The HAWC-OAWL IIP is a three year period of performance, with a flexible start date of March 2014. The entry Technology Readiness Level for the overall HAWC system is TRL3 and the exit is expected to be TRL5.
• Develop a rugged wind and high spectral resolution aerosol lidar to measure aerosol transport, and aerosol, wind, and cloud interactions • Demonstrate HAWC-OAWL wind and aerosol measurements in airborne flight tests • Validate HAWC aerosol measurements and develop new aerosol and wind data products

New and innovative technologies will lead to flight instruments that are smaller with reduced materials, costs and build time. Furthermore, by early investment in the life cycle of an instrument and demonstrating performance, space-flight instrument builds will encounter less development risk, cost, and schedule uncertainty.
Strategy
As promising new technologies emerge from core programs in government, private industry, academic, or other non-profit organizations, proposers are encouraged to incorporate these latest developments into their instrument concepts. NRAs are expected to solicit some combination of feasibility studies; requirements analysis; design; construction of breadboards, prototypes, and engineering models; and laboratory and field demonstrations. Individual NRAs may focus on specific science questions or may address the whole science program. IIP provides a continuing source of mature instrument designs merging state-of-the-art technologies with measurement objectives available for use in the next generation of science missions.
Program Content Determined via NASA Research Announcements (NRA)
A key element of the Instrument Incubator Program's strategy is the advanced studies and ground-based demonstration phase. NRAs are released regularly to ensure that a steady stream of instrument technologies is available for future measurements. This activity will be conducted via a peer reviewed process by government, academic, and private industry research teams knowledgeable in remote-sensing and in situ measurement techniques to study global variables of the Earth system. The program encourages the use of the latest remote sensing technologies resulting from NASA's technology development programs and combining them with other government agency, academic and private industry investments to develop new instrument systems and subsystems.
