CO2equi: Convert flux data to CO2 equivalent

In MadoShi64/rstep: rstep: a workflow for STEP-GENDEC-CN model under R

Convert flux data to CO2 equivalent

Description

CH4 and N2O emissions rates can be converted to CO2 equivalents using the ‘100-yr global warming potential’ factors as follows: 1 kg N2O = 298 kg CO2 equivalents. 1 kg CH4 = 25 kg CO2 equivalents. Please note that, according the most recent IPCC report (IPCC, 2013), the conversion of CH4 into CO2eq. should be: 1 kg CH4 = 34 kg CO2 equivalents Reference cited: IPCC (2013) Climate change 2013: the physical science basis. Intergovernmental Panel on Climate Change. Available at https://www.ipcc.ch/report/ar5/wg1/ "1 kg CH4-C = (16/12)x1 kg CH4 = 1.33 kg CH4". "1 kg CO2-C = (44/12)x1 kg CO2 =3.67 kg CO2". "1 kg N2O-N = (44/28)*1 kg N2O = 1.57 kg N2O"
