General Description  

Location

NASA / Wallops Flight Facility, Wallops Island, VA

Period

May & June, 1998

Objectives 

To test and evaluate the holographic scanning telescope technology in an airborne application (3-D mapping of boundary layer aerosol and cloud structure).
Demonstrate conical scanning airborne lidar measurements of aerosol backscatter and develop data processing and analysis routines for same.
 
 
Several successful engineering test flights were conducted between April and June of 1998, and is available for use in airborne science investigations.
The HARLIE instrument is useful in atmospheric dynamics experiments, using aerosol backscatter as a tracer for atmospheric motions and structure. Standard data products not only include 3-D aerosol backscatter maps, but also 3-D atmospheric boundary layer heights and cloud boundaries. Due to its small size and ability to use a conventional instrument window, HARLIE can be accommodated on a variety of aircraft. HARLIE's design makes it very easy and inexpensive to integrate into most research aircraft. It has a real-time 2-D color backscatter image display, and is able to store over 250 hours worth of data. HARLIE can be operated by a single person with minimal training. During ground-based campaigns, HARLIE is set up to run 24/7 with automatic data transfer to networked devices.
