A One-Year Cloud Climatology Derived from the Micro Pulse Lidar

نویسنده

  • G. G. Mace
چکیده

A cloud detection algorithm that attempts to identify all of the significant power returns from the vertical column above the micro pulse lidar at all times was applied to one year of micro pulse lidar data collected at the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) central facility near Lamont, Oklahoma. The results of this analysis are presented, and the potential significance of such long-term lidar measurements is considered.

Comparison of cloud statistics from spaceborne lidar systems

The distribution of clouds in a vertical column is assessed on the global scale through analysis of lidar measurements obtained from three spaceborne lidar systems: LITE (Lidar In-space Technology Experiment, NASA), GLAS (Geoscience Laser Altimeter System, NASA), and CALIOP (Cloud-Aerosol LIdar with Orthogonal Polarization). Cloud top height (CTH) is obtained from the LITE profiles based on a s...

Conditional Random Fields for Airborne Lidar Point Cloud Classification in Urban Area

Over the past decades, urban growth has been known as a worldwide phenomenon that includes widening process and expanding pattern. While the cities are changing rapidly, their quantitative analysis as well as decision making in urban planning can benefit from two-dimensional (2D) and three-dimensional (3D) digital models. The recent developments in imaging and non-imaging sensor technologies, s...

The NASA Micro-Pulse Lidar Network (MPLNET): an overview and recent results MPLNET, Red de lidares Micro-pulso de la NASA: Descripción general y resultados recientes

We present the formation of a global ground-based eye-safe lidar network, the NASA Micro-Pulse Lidar Network (MPLNET) – founded in 2000. The aim of MPLNET is to acquire long-term observations of aerosol and cloud vertical profiles at unique geographic sites collocated with sunphotometers in the NASA Aerosol Robotic Network (AERONET). These joint MPLNET/AERONET sites collect data on aerosol and ...

A comparison of Rayleigh and sodium lidar temperature climatologies

Temperature measurements from the PCL Rayleigh lidar located near London, Canada, taken during the 11 year period from 1994 to 2004 are used to form a temperature climatology of the middle atmosphere. A unique feature of the PCL temperature climatology is that it extends from 35 to 95 km allowing comparison with other Rayleigh lidar climatologies (which typically extend up to about 85 km), as w...

Long-term trend analysis and climatology of tropical cirrus clouds using 16 years of lidar data set over Southern India

Sixteen-year (1998–2013) climatology of cirrus clouds and their macrophysical (base height, top height and geometrical thickness) and optical properties (cloud optical thickness) observed using a ground-based lidar over Gadanki (13.5 N, 79.2 E), India, is presented. The climatology obtained from the ground-based lidar is compared with the climatology obtained from 7 and a half years (June 2006–...
