 +The Tier 1 methodology for the emissions from salt mining represents only a small portion of emissions from this sector - few than 4%, depending on the PM fraction. Considering the limited scale of the activity and emission, the part is considered to be below the significance for higher Tiers. Please see the small relevance of this under trend diskussion.

-In particular, this concerns input variables on humidity and wind speed, which are differentiated into regions. Due to data availability, the regions are represented by the administrative states (German Länder), which does not necessarily represent characteristic weather regimes. Regionality can be increased by merging urban and surface states. Parameters on weather as well as on areas can thus be improved, in a first step by using open wheather data back to 1990.+In particular, this concerns input variables on humidity and wind speed, which are localized according to the administrative states of Germany. Larger city states (Berlin, Hamburg and Bremen) were merged with the respective larger states (Brandenburg, Schleswig-Hollstein, Niedersachsen) as the city states do not neccessarily represent the local weather conditions.  
 +Parameters on weather as well as on areas can thus be improved in the model above. In a first this was done by using weather data from the German Weather Service (DWD), which may be obtained as daily station data from the Open Data Portal: ClimateDataCenter (CDC) of the DWD URL: https://opendata.dwd.de/climate_environment/CDC/observations_germany/climate/daily/kl/

 With the help of the GB tools, IEFs are estimated on an annual basis, which are used for the inventory method AR x EF. The emission factors are virtual, but the calculation of this is modified by national circumstances on the parameters. So we would name the EF as country-specific. With the help of the GB tools, IEFs are estimated on an annual basis, which are used for the inventory method AR x EF.
