TODWL is an airborne Doppler wind lidar that can be used to
investigate issues related to local scale wind flows, fine scale model
validation, interpretation of space-based DWL data, and the calibration or
validation for other lidars. The instrument is a 5 mJ
2 micron laser with a 10cm telescope and two axis scanner. The
scanner allows the beam to be pointed within a 60 degree azimuthal arc in
the forward position and plus minus 120 degree elevation arc (with 0
pointing horizontal). The lidar scanner is mounted in a side door of the
aircraft, which allows scanning upward as well as downward. The aircraft
is an unpressurized Navy Twin Otter with a cruise speed of 95-160 knots. It
is equipped with a variety of particle probes and turbulence sensors. It
has dropsonde capability and at least two independent attitude/position
instrument sets.
At this time, this web site is intended to communicate with those
familiar with DWL technology and its applications. In the near future, a
paper will be published for the more general science community.
