• Micro Pulse Lidar Systems (MPL)
• GSFC Patent
• First commercial, autonomous, eye-safe aerosol
  cloud lidar (50 sold worldwide)
• 523 or 527 nm wavelength
• low energy, fast pulse rate
• small FOV, no multiple scattering

Each MPL instrument MUST be sited with a
reliable sunphotometer
The MPL and MPLNET recently won a Technology
Transfer award from the Federal Laboratory
Consortium

• Lidar identifies the height, structure, and
  growth/decay of the planetary boundary layer
  (PBL)

7

• Level 1 Lidar Signals
• 1 minute, 75 meters
• near real time - next day
• Level 1.5b Layer Heights
• 1 minute gridded product
• near real time - next day
