The Joint Airport Weather Studies (JAWS) Project conducted a field investigation during the summer of 1982 in and around Denver, Colorado. The principal objective of JAWS was to study convectively driven downdrafts and resulting outflows near the earth's surface. In general, information on wind fields was collected in several ways, including the use of Doppler radars, instrumented aircraft and rawinsondes. In particular, JAWS was marked by the participation of two ground-based CO2, 10.6 µm Doppler lidars, one operated by NASA/Marshall and the other by NOAA/WPL. Observations of surface winds (as well as other parameters) in the area of the lidars were made routinely using 27 Portable Automated Mesonet (PAM) stations operated by the National Center for Atmospheric Research (NCAR). Figure 1 shows the location of the lidars, PAM stations and Doppler radars (CP–2, CP–3 and CP–4, operated by NCAR).

Prior to 1983, 95% of signal processing for the NOAA coherent lidar system was performed off-line. This limited real-time processing and display performance hampered the utility of the lidar in experiments such as JAWS1 (Joint Airport Weather Study) where the inability to detect and track interesting meteorological phenomena severely limited the quantity of useful data-recorded. During JAWS, we were able to monitor radial velocities in only one range gate at any given time, thus often missing the presence of an interesting event occurring at another range.

In 1980, NOAA constructed a coherent, pulsed, Doppler lidar1 and reported2 early results of aerosol backscattering at λ = 10.6 μm. Since that time, considerably more data have been taken, processed, and archived at WPL in Boulder to form a data base that can be analyzed statistically. The results of such an analysis are presented here.

The U.S. Navy is pursuing the use of CO2 laser radar technology for a variety of applications. Rather than attempt to describe the specifics of these applications and rapidly get into classification problems, three major areas which support the uses of the technology will be described. Critical areas include componentry, signatures, and airborne imaging sensors. Under the componentry area a manufacturing technology program for CO2 waveguide lasers will be described. For the signatures part of this discussion a Navy built and operated van installation (Navy Active Target Signatures (NATS) System) will be described. Finally some results from a flight test conducted on a UH-IN helicopter of an imaging sensor will be reviewed.

Although CO2 laser Doppler velocimeters have been available in semi-breadboard form for over 10 years, only with the introduction of compact, reliable wave-guide lasers have these systems become available for the tactical environment. Today requirements can be identified for using rugged, compact laser velocimeters for monitoring wind velocities in the boost phase regime in support of free-flight rocket systems.

The Laser True Airspeed System (LATAS) developed by the RAE and RSRE and installed on the RAE HS125 research aircraft has proved exceptionally reliable and rugged. During over two years of varied flight trial experience the experimental equipment has never needed any special treatment. Optical readjustment has only been required on fitting a new laser; the latest installation has been in place 14 months with an average of two flights per week. This demonstrates that commercial ‘fit and forget’ CW Doppler Laser systems are now a practical proposition within the present state of the art.
