CEOS Instrument: HDWL (3D Winds)




Instrument:HDWL (3D Winds)
Agency: NASA
Mission: 3D Winds
Status:Proposed
Type:Doppler lidar
Description:"Tropospheric winds for weather forecasting and pollution transport
Spatial Resolution: 300 km along track horizontal resolution
Swath Width: View 45 degrees of nadir at four azimuth angles: 45, 135, 225, 315 deg.
Wavebands: 2.051 ?m and 0.355 ?m
Technology: Doppler lidar
Description: Lidar measuring the Doppler shift of echoes from atmospheric components such as air molecules and aerosol. A UV wavelength is exploited, but other ones are possible. Side looking, measuring the radial component of wind in clear air. The resolution is controlled by sampling needs, and may be in the range of 100-200 km, aside of the orbital track. Applicable only in LEO.
