"The NASA Micro Pulse Lidar Network: An overview of NASA's global ground-based lidar network"

SPEAKER: Dr. Judd Welton - NASA Airborne Science Program

DATE: September 15, 2022

Time: 3:30 - 4:30 pm MST



The NASA Micro-Pulse Lidar Network (MPLNET) is a global federated network of polarized Micro-Pulse Lidar (MPL) systems. Almost all sites are co-located with the NASA Aerosol Robotic Network (AERONET) to provide joint data on column and vertically resolved aerosol and cloud data. MPLNET lidars run continuously, capturing the full diurnal cycle. MPLNET began in 2000, and there have been 79 sites deployed worldwide, with 24 currently active and 7 more in planning or proposal stages. Many MPLNET sites have now collected over 10 years of data on atmospheric structure, cloud and aerosol properties, and mixed-layer diurnal evolution. MPLNET has matured over time, adding new instrumental and data product capabilities as well as web-based user tools and APIs. There have been three Version releases of MPLNET, each marking significant maturation events. The current version, V3, was officially released in November 2021 after 6 years of intensive development. V3 MPLNET products include signals and diagnostics, and cloud, aerosol, and mixed-layer height products. I will provide a brief history of MPLNET and an overview of V3 instrument capabilities, data products, and web tools and APIs that are available to the research community. I will present our methodology for the generation of new level 3, diurnal products and climatologies. Finally, I will discuss partnerships with other lidar networks and our efforts to maintain interoperability with other networks.
