Uncertainties in primary PM emissions from CAMS-REG at the grid cell level. D5.3
report
This deliverable presents a comprehensive methodology to estimate uncertainties in gridded, regional primary PM emissions. The uncertainties data consist initially of country-level emission uncertainties, gridded uncertainties related to the spatial distribution, and spatial correlation lengths. These estimates are based on a wide range of data at the highest level of detail possible (generally per sub-sector and fuel) and aggregated to the GNFR sector using error propagation. We present an overview of the data that is used and how everything is combined. The results show that significant uncertainties exist in primary PM emissions, both at the national scale and in the spatial distribution.Next, we demonstrate an optimization procedure, which is used to create consistency between country-level and gridded uncertainties. The results of the optimization procedure are scaled spatial correlation lengths and gridded uncertainties, which match with the country-level uncertainties. In this way, the gridded uncertainties can be used directly instead of having to combine them with country-level data. This is more user-friendly, but also increases consistency and statistical soundness.
