Measurement of Atmospheric Turbulence by 2-μm Doppler Lidar

Mars Atmospheric Characterization Using Advanced 2-μm Orbiting Lidar

Mars atmospheric characterization is critical for exploring the planet. Future Mars missions require landing massive payloads to the surface with high accuracy. The accuracy of entry, descent and landing (EDL) of a payload is a major technical challenge for future Mars missions. Mars EDL depends on atmospheric conditions such as density, wind and dust as well as surface topography. A Mars orbit...

Measurement of Atmospheric Turbulence

How light and sound propagate through the optically clear atmosphere has been of interest to children, philosophers, scientists, and engineers since antiquity. The quantum leap in our understanding of wave propagation through the turbulent atmosphere, however, came with the pioneering work by Valeryan Tatarskii and collaborators in the 1950’s and 1960’s. Their work enhanced dramatically our abi...

Comparison of balloon-carried atmospheric motion sensors with Doppler lidar turbulence measurements.

Magnetic sensors have been added to a standard weather balloon radiosonde package to detect motion in turbulent air. These measure the terrestrial magnetic field and return data over the standard uhf radio telemetry. Variability in the magnetic sensor data is caused by motion of the instrument package. A series of radiosonde ascents carrying these sensors has been made near a Doppler lidar meas...

LIDAR for Atmospheric Measurement and Probing

This paper describes a LIDAR for atmospheric measurement and probing (LAMP). The LAMP system is a commercial LIDAR unit that uses the design of boundary layer LIDAR (BLL), an optical radar technology developed at the National Atmospheric Research Laboratory (NARL) for atmospheric applications. The LAMP technology is useful for remote monitoring of atmospheric particulate and clouds in the tropo...
