MiniMPL

Mini Micro Pulse LiDAR

The Mini Micro Pulse LiDAR (MiniMPL) is a small form factor, low-power, elastic backscatter lidar. The instrument is a ground-based, optical, remote-sensing system designed to determine the altitude of cloud sand to detect atmospheric aerosols. Pulses of energy are transmitted into the atmosphere; the energy scattered back to the transceiver is collected and measured as a time-resolved signal, thereby detecting clouds and aerosols in real time. MPL and MiniMPL are the only LiDARs simultaneously approved for NASA MPLNET, US Dept of Energy ARM program, and EUMETNET.

The MiniMPL delivers advanced cloud and planetary boundary layer data for atmospheric profiling up to 15 km. Make the fastest and most accurate decisionsbased on reliable information.

Allow co-polarized and cross-polarized backscatter measurements that provide information on the cloud phase (liquid versus ice).

Enable the cloud layer mapping feature that outperforms ceilometers by observing through moderately thick fog and low clouds–fora greater number of detected layers, a better range resolution, and faster reporting times.

Use data to calculate cloud phase anddepolarizing aerosols, cloud scattering cross sections and optical thicknesses, planetaryboundary layer heights,and aerosol extinction and optical thickness profiles–including those intothe stratosphere in nighttime cases.

Utilize the all solid-state laser that provides more than 10,000 hours of uninterrupted service; a robust 80mm co-axial transmit/receive aperture; and a field replaceable fiber-coupled, photon-counting detector that needs no realignment.

Light Detection and Ranging (LiDAR)

  • Pulses of laser energy are transmitted into the atmosphere; the energy scattered back to the transceiver is collected and measured as a time-resolved signal, thereby detecting clouds and aerosols in real time.
  • The transmission path starts at the laser. The beam is first expanded, and then the polarizationorientation is set. Finally, the lasergoes through a second stage of expansion before it leaves thetelescope. Two polarization states leave the MiniMPL, co-pol and cross-pol.
  • On the return path, light that has been scattered off particles in the atmosphere enters the MiniMPLand follows the same path as the transmit beam. Once it enters the telescope,it is collected by the receiver and focused onto the detector (not shown).

The Lifecycle Care Program ensures MiniMPL integrity and performance vital to your research mission for three years or three calls (whichever comes first). When conducting complex and time-intensive laboratory or field measurements, it is critical to avoid downtime and ensure data collection accuracy. The program consists of three key deliverables for each year or call:

  1. Instrument logistics
  2. Instrument integrity
  3. Instrument performance

Lifecycle Care Program Includes:

LOGISTICS

  • Shipping to and from Droplet Measurement Technologies facility
  • Customs handling, including CARNET ATA if required

INTEGRITY

  • Incoming instrument evaluation and health check

PERFORMANCE

  • Software and firmware validation
  • 100%-unit functionality test
  • Calibration data
  • Calibration report
  • Certificate of calibration

At times, our technician might discover an instrument issue, which might not be covered by the Lifecycle Care Program or by our product warranty. In such case, we will reach out to you with a service and repair estimate to allow you to provide us with the next steps of action
