Methodical study nitrous oxide eddy covariance measurements quantum cascade
2010/1/14
Nitrous oxide fluxes were measured at the Lägeren CarboEurope IP flux site over the multi-species mixed forest dominated by European beech and Norway spruce. Measurements were carried out during ...
Suitability of quantum cascade laser spectroscopy for CH4 and N2O eddy covariance flux measurements
Suitability quantum cascade laser spectroscopy CH4 N2O eddy covariance flux measurements
2010/1/14
A quantum cascade laser spectrometer was evaluated for eddy covariance flux measurements of CH4 and N2O using three months of continuous measurements at a field site. The required criteria for eddy co...
Multi-station synthesis of early twentieth century surface atmospheric electricity measurements for upper tropospheric properties
vertical columnar current density tropospheric properties surface
2010/1/27
The vertical columnar current density in the global atmospheric electrical circuit depends on the local columnar resistance. A simple model for the columnar resistance is suggested, which separates th...
Statistical and neural classifiers in estimating rain rate from weather radar measurements
Statistical and neural classifiers rain rate weather radar measurements
2010/1/26
Weather radars are used to measure the electromagnetic radiation backscattered by cloud raindrops. Clouds that backscatter more electromagnetic radiation consist of larger droplets of rain and therefo...
Elastic oscillations of water column in the 2003 Tokachi-oki tsunami source:in-situ measurements and 3-D numerical modelling
Elastic oscillations water column Tokachi-oki tsunami source 3-D numerical modelling
2009/12/30
During the 2003 Tokachi-Oki tsunamigenic earthquake the real-time JAMSTEC observatory obtained records which provided a unique opportunity to have a look deep inside the tsunami source. Considering wa...
Measurements of hydrocarbon emissions from a boreal fen using the REA technique
Measurements hydrocarbon emissions boreal fen REA technique
2010/1/13
Fluxes of biogenic volatile organic compounds (VOC) and methane were measured above a boreal fen. Vegetation on the fen is dominated by Sphagnum mosses and sedges. A relaxed eddy accumulation (REA) sy...
