Methane (CH4) fluxes were investigated in a subarctic Russian tundra site in a multi-approach study combining plot-scale data, ecosystem-scale eddy covariance (EC) measurements, and a fine-resolution land cover classification scheme for regional upsc

The atmospheric greenhouse gas (GHG) budget of a restored wetland in western Denmark was established for the years 2009–2011 from eddy covariance measurements of carbon dioxide (CO2) and methane (CH4) fluxes. The water table in the wetland, which w

Surface meteorology and flux data are presented from five sites in a transect crossing a 100-km-wide coastal region of west Greenland. The sites cover a variety of Arctic types: snow covered, bog and arid. The measurements show a comparatively small

An eddy covariance system is described which has been developed jointly at a number of European laboratories and which was used widely in HAPEX-Sahel. The system uses commercially available instrumentation: a three-axis sonic anemometer and an IR gas

In most laser cutting applications, the laser beam is focused to a size of 0.15 - 0.3 mm and positioned in the centre of the cutting nozzle, which has a diameter of 0.8 - 2 mm. At laser contour cutting, the focused beam spot is usually centre in the
