CH4 column over the Amazon can occur some months prior to the peak in the water table (the measure used to characterise the ’wetland’). The parameterisation is then applied globally and used in the GEOS-CHEM atmospheric chemistry model. This work is highly relevant as many of the leading land surface models (e.g., the US Community Land Model (Riley et al., 2011), the Joint UK Land Environment S...

Seasonal variability of tropical wetland CH4 emissions: the role of the methanogen-available carbon pool

We develop a dynamic methanogen-available carbon model (DMCM) to quantify the role of the methanogenavailable carbon pool in determining the spatial and temporal variability of tropical wetland CH4 emissions over seasonal timescales. We fit DMCM parameters to satellite observations of CH4 columns from SCIAMACHY CH4 and equivalent water height (EWH) from GRACE. Over the Amazon River basin we fou...

Estimation of the Carbon Footprint in Dairy Sheep Farm

By 2050, the earth’s population is expected to be more than 9 billion. The need for secure food and water supply will force agriculture to increase production. The major greenhouse gases (GHGs) from the livestock sector are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) throughout the production process. These gases are the key contributor to an in...
