Maximum-likelihood reconstruction of photon returns from simultaneous analog and photon-counting lidar measurements
Maximum-likelihood reconstruction photon return simultaneous analog photon-counting lidar measurement
2011/8/2
Abstract: We present a novel method for combining the analog and photon-counting measurements of lidar transient recorders into reconstructed photon returns. The method takes into account the statisti...
Tree ring-based February–April temperature reconstruction for Changbai Mountain in Northeast China and its implication for East Asian winter monsoon
February–April temperature Northeast China Changbai Mountain winter monsoon
2009/12/3
Long-term climatic records are scarce in the northeast Asia for understanding the behavior of the East Asian Winter Monsoon. Here we describe a 250-year February–April temperature reconstruction (TCBM...
A few prospective ideas on climate reconstruction：from a statistical single proxy approach towards a multi-proxy and dynamical approach
climate reconstruction dynamical approach multi-proxy
2009/12/3
Important progresses have been made in palaeoclimatological studies by using statistical methods. But they are in somewhere limited as they take the present as an absolute reference. This is particula...
Two-dimensional reconstruction of past sea level (1950–2003) from tide gauge data and an Ocean General Circulation Model
past sea level Ocean General Circulation Model Two-dimensional
2009/12/3
A two-dimensional reconstruction of past sea level is proposed at yearly interval over the period 1950–2003 using tide gauge records from 99 selected sites and 44-year long (1960–2003) 2°×2° sea level...
Climate reconstruction from pollen and δ13C records using inverse vegetation modeling – Implication for past and future climates
Climate reconstruction future climates
2009/12/3
An improved inverse vegetation model has been designed to better specify both temperature and precipitation estimates from vegetation descriptions. It is based on the BIOME4 vegetation model and uses...
Grid resolution dependence in the reconstruction of an atmospheric tracer source
Grid resolution dependence reconstruction atmospheric tracer source
2009/11/9
Methods for reconstructing sources of inert atmospheric tracers from ground measurements are currently studied, tested, and even implemented (in accident-type radionuclide release backtracking, for re...
Limb scatter ozone retrieval from 10 to 60 km using a multiplicative algebraic reconstruction technique
Limb scatter ozone multiplicative algebraic reconstruction technique
2009/9/14
The OSIRIS instrument onboard the Odin spacecraft routinely measures vertical profiles of spectrally dispersed, limb scattered sunlight from the upper troposphere into the lower mesosphere. These meas...
Aerosol mass closure and reconstruction of the light scattering coefficient over the Eastern Mediterranean Sea during the MINOS campaign
Aerosol mass light scattering coefficient Eastern Mediterranean Sea MINOS campaign
2009/2/16
As part of the Mediterranean Intensive Oxidant Study (MINOS) performed during August 2001 in the Eastern Mediterranean Region, intensive measurements of chemical and radiative properties of atmospher...
2-D reconstruction of atmospheric concentration peaks from horizontal long path DOAS tomographic measurements: parametrisation and geometry within a discrete approach
2-D reconstruction of atmospheric concentration peaks horizontal long path parametrisation geometry discrete approach
2009/1/4
In this study, we theoretically investigate the reconstruction of 2-D cross sections through Gaussian concentration distributions, e.g. emission plumes, from long path DOAS measurements along a limite...
Inverse modelling-based reconstruction of the Chernobyl source term available for long-range transport
Chernobyl source long-range transport
2008/12/4
The reconstruction of the Chernobyl accident source term has been previously carried out using core inventories, but also back and forth confrontations between model simulations and activity concentra...
Reconstruction of erythemal UV-doses for two stations in Austria: a comparison between alpine and urban regions
erythemal UV-doses Austria alpine urban regions
2008/11/24
The aim of this study is the reconstruction of past UV-doses for two stations in Austria, Hoher Sonnblick and Vienna, using a physical radiation transfer model. The method uses the modeled UV-dose und...
