The Mini-MOPA CO2 Doppler lidar is housed in a mobile laboratory constructed from a modified sea-going cargo container. It provides vertical profiles of wind speed, wind direction, turbulence, aerosol species concentration (DIAL – introduction to Differential Absorption Lidar (DIAL) techniques), cloud geometry and microphysical parameters. Research applications include:
Wavelength | 9.2 - 11.3 µm line tunable (fully eye-safe) |
Pulse energy | 2 mJ |
Pulse rate | < 300 Hz |
Pulse length | 0.5 - 10 µs |
Wavelength switching rate | < 50 Hz |
Scan | Upper hemisphere |
Range Resolution | > 60 m |
Time Resolution | 0.3 sec (100 pulse avg.) |
Minimum range | 90 m |
Maximum range | 5 - 12 km |
Velocity accuracy | > 5 cm s-1 |
