Abstract. Tailings ponds in the Alberta oil sands region are significant sources of fugitive emissions methane to atmosphere, but detailed knowledge on spatial and temporal variabilities is lacking due limitations methods deployed under current regulatory compliance monitoring programs. To develop more robust representative for quantifying emissions, three micrometeorological flux (eddy covaria...

Abstract Riparian forests are known as hot spots of nitrogen cycling in landscapes. Climate warming speeds up the cycle. Here we present results from a multi-annual high temporal-frequency study soil, stem, and ecosystem (eddy covariance) fluxes N 2 O typical riparian forest Europe. Hot moments (extreme events emission) lasted quarter period but contributed more than half soil fluxes. We demons...

The Congo basin is home to the second-largest tropical forest in world. Therefore, it plays a crucial role regional water cycle, global carbon cycle and continental greenhouse gas balance. Yet very few field-based data on related processes exist. In wake of change, there need for better understanding current future response biome this region. A new long-term effort has been set up measure excha...
