DEVELOPMENT OF A PROCEDURE FOR VERTICAL STRUCTURE ANALYSIS AND 3D-SINGLE TREE EXTRACTION WITHIN FORESTS BASED ON LIDAR POINT CLOUD
Canopy Vertical structure Tree crown 3D model Lidar Point cloud
2015/11/10
A procedure for both vertical canopy structure analysis and 3D single tree extraction based on Lidar raw point cloud is presented in this paper. The whole study area is segmented into small study cell...
Different approaches to the classification of vertical structure in homogeneous and heterogeneous forests
height variability forest status survey NFI structural classification
2015/3/19
The paper shows difficulties in the evaluation of the forest status when considering forests with different height structure (uneven-aged forests). It is the main problem in categorizing such forests....
Vertical structure of Antarctic tropospheric ozone depletion events: characteristics and broader implications
Vertical structure Antarctic tropospheric ozone depletion events characteristics and broader implications
2010/8/25
The majority of tropospheric ozone depletion event (ODE) studies have focussed on time-series measurements, with comparatively few studies of the vertical component. Those that exist have almost exclu...
Vertical structure of aerosols and water vapor over West Africa during the African monsoon dry season
Vertical structure water vapor West Africa African monsoon dry season
2009/11/9
We present observations of tropospheric aerosol and water vapor transport over West Africa and the associated meteorological conditions during the AMMA SOP-0 dry season experiment, which was conducted...
How important is the vertical structure for the representation of aerosol impacts on the diurnal cycle of marine stratocumulus?
vertical structure aerosol impacts diurnal cycle marine stratocumulus
2009/6/22
Large-Eddy Simulations (LES) are performed to examine the impact of hygroscopic aerosols on the diurnal cycle of marine stratocumulus clouds, under varying meteorological forcing conditions. When the ...
Vertical Structure of Currents and Deep Temperatures in the Western Sargasso Seal
Vertical Structure Currents Deep Temperatures Western Sargasso Seal
2009/3/7
Currents and temperatures were measured as a function of depth at two locations during the Mid-Ocean Dynamics Experiments of 1972–73. Instrumented profiling floats were used and flows were determined ...
Vertical Structure of Time-Dependent Flow Dominated by Friction in a Well-Mixed Fluid
Time-Dependent Flow Well-Mixed Fluid Friction
2009/2/18
Solutions of a linear hydrodynamic equation of motion with linear boundary conditions are obtained to describe the horizontal current, as a function of depth and time, determined by a given history of...
Moored Observations of Deep Low-Frequency Motions in the Central Pacific Ocean：Vertical Structure and Interpretation as Equatorial Waves
Pacific Equatorial Ocean Dynamics Deep Low-Frequency Motions Central Pacific Ocean
2009/1/16
Two-year time series of current and temperature collected in the deep equatorial central Pacific 0cean as part of the Pacific Equatorial Ocean Dynamics (PEQUOD) project indicate that motions with vert...
Horizontal and Vertical Structure of the Gulf Stream Velocity Field at 68°W
Vertical Structure Gulf Stream Velocity Field 68°W
2009/1/13
A curent meter mooring, instrumented from the bottom into the thermocline, was deployed in the Gulf stream at 68°W for a year. Data from the uppermost instrument indicate the Gulf Stream moved back an...
The Vertical Structure of Currents on the North West Shelf of Australia at Subtidal Frequencies
North West Shelf Australia Subtidal Frequencies
2009/1/12
An EOF analysis of current meter data collected on the North West Shelf of Australia (NWS) suggested that the major part of the low-frequency (subinertial) circulation on the shelf was wind force. The...
Evaluation of Vertical Structure Functions for the Analysis of Oceanic Data
Vertical Structure Functions Oceanic Data
2009/1/10
It is feasible to construct vertical structure functions for the analysis of oceanic data, from the gravest scales sustained by the water column to fine-structure scales. The short scales need not be ...
On the ability of chemical transport models to simulate the vertical structure of the N2O, NO2 and HNO3 species in the mid-latitude stratosphere
chemical transport models vertical structure N2O HNO3 species mid-latitude stratosphere
2009/1/7
In this paper we study the impact of the modelling of N2O on the simulation of NO2 and HNO3 by comparing in situ vertical profiles measured at mid-latitudes with the results of the Reprobus 3-D CTM (T...
Vertical Structure of Midlatitude Mesoscale Instabilities
Vertical Structure Midlatitude Mesoscale Instabilities
2009/1/6
Instability processes in frontal jet regions outside the western boundary currents are examined for their ability to produce mesoscale variability comparable to that observed in the open ocean. The im...
Vertical Structure of Low Frequency Variability in the Eastern Equatorial Pacific Ocean
Vertical Structure Eastern Equatorial Pacific Ocean Low Frequency Variability
2009/1/6
The vertical structure of low frequency velocity and temperature variability in the eastern equatorial Pacific Ocean is examined using surface and subsurface moored current meter data from 0°, 110°W b...
Vertical structure and diurnal variability of ammonia exchange potential within an intensively managed grass canopy
Vertical structure diurnal variability ammonia exchange grass canopy
2010/1/19
Stomatal ammonia compensation points (χs) of grass species on a mixed fertilized grassland were determined by measurements of apoplastic [NH4+] and [H>+] in the field. Calculated χs values were compar...
