N 2 O flux and carbon isotope (δ 13 C) analyses Samples of dissolved N 2 O, CH 4, δC–CO 2, and δC–CH 4 were collected during each of the floating chamber flux …

Deforestation and land-use change are accelerating in the Congo Basin and elsewhere in the tropics affecting the soil-atmosphere exchange of greenhouse gases (GHG). There is a lack of data from Central Africa. We quantified fluxes of CO2, CH4, and N2O at the soil-atmosphere interface in a secondary forest, a cocoa agroforest, and an unfertilized cropland. Soil respiration was highest in the

For CO2 concentrations, an open-path infrared gas analyzer was used, while N2O and CH4 concentrations were measured with a recently developed continuous-wave quantum cascade laser absorption spectrometer (QCLAS).

This so called greenhouse gas effect is av M Henriksson · Citerat av 1 — kens produktion från vaggan till gårdsgrind är i huvudsak metan (CH4), lustgas (N2O) och koldioxid (CO2).

Frontiers in Environmental Science. 9 , 630721 Abstract We evaluated the spatial structures of nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4) fluxes in an Acacia mangium plantation stand in Sumatra, Indonesia, in drier (August) and wetter (March) seasons. A 60 × 100-m plot was established in an A. mangium plantation that included different topographical elements of the upper plateau, lower plateau, upper slope and foot slope Gaseous emissions (NH3, N2O, CH4, CO2, H2O) of both heaps, covered for the purpose by ventilated greenhouses, were continuously measured over four periods (57 days in total).

During the period 2010-2013, we simultaneously measured carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) fluxes using the flux-gradient

A study of the greenhouse gases methane and nitrous oxide during a year at (21 % O2) och halten CO2, O2 och CH4 mättes under 4 dygn. "Variations of dissolved greenhouse gases (CO2, CH4, N2O) in the Congo River network overwhelmingly driven by fluvial-wetland connectivity let, dessa är koldioxid (CO2), metan (CH4), kväveoxid (N2O), hydrofluorkarboner (HFCs), perfluorkarboner one metric tonne of carbon dioxide equivalent;.

Ice core records of the major atmospheric greenhouse gases (CO2, CH4, N2O) and their isotopologues covering recent centuries provide evidence of biogeochemical variations during the Late Holocene and pre-industrial periods and over the transition to the industrial period.
