Quantitative information or data is based on quantities obtained using a quantifiable measurement process. In contrast, qualitative information records qualities that are descriptive, subjective or difficult to measure.
Current global observational and modelling capabilities allow scientists to produce estimates of the carbon budget, but many uncertainties remain. An EU-funded initiative was therefore established to provide more and better data on carbon dioxide (CO2) and methane (CH4) through a global carbon observation and analysis system.
