- | ------ | + | ===== Recalculations ===== |
+ | |||
+ | Recalculations were necessary due to revised emissions model parameters for the whole time. Because of the particular weather sensitivity of the model, there are years with higher emissions, which is not counterbalanced by reductions from the area correction. There are changes for the years 1990 to 2009 because of the corrected area data, without specific modeling. The changed weather data can be found in the data set for the adjustment of all years starting in 2010. | ||

Salt production is a sub-category of the mining activities in respect of the country specific approach used. Currently, a Tier 1 method is used: information on production of salts are multiplied with emission factors for TSP and PM. | Salt production is a sub-category of the mining activities in respect of the country specific approach used.
