-noch zu verwenden: 
-Regionalität: wegen der Bedeutung der Regionalität statt Administration Zusammenführung von Stadt- und Flächenstaaten bei Wetter und Flächen? 
-Test: geringe Abweichungen waren erkennbar, aber unvermeidlich, weil Wetterdaten hier teilweise revisionsbedürftig und kaum als Mittel darstellbar. 
-verwendet für die Anpassung der Datensätze im Jahrestool wurden (Datenübernahme): 
- 
-Flächen im Zeitverlauf: Die Abbauflächen ändern sich im Zeitverlauf, aber rückwirkend liegen nicht alle Daten vor. 
--> Die zeitlichen Verläufe werden grob durch die bekannten Abbaumengen abgebildet. 
--> Vor 2010 liegen auch keine DWD-Datenauswertungen vor, was konsistent sein muss. 
--> Das Auslaufen der BK-Tagebaue hat durch die erfolgte Flächenbereinigung keine Auswirkung. 
--> Erst bei Verwendung eines neuen, aktuelleren CLC-Datensatzes müsste die Bereinigung neu erfolgen, weil BK-Tagebaue wegfallen. 
-1. Fazit für die zu erwartenden Rekalkulationen 
-Wegen der besonderen Wettersensitivität des Modells wird es Jahre mit höheren Emissionen geben, was nicht durch Verringerungen aus der Flächenkorrektur ausgeglichen wird. Es gibt wegen der korrigierten Flächendaten Änderungen für die Jahre 1990 bis 2009, ohne dass diese spezifisch modelliert wurden. Alle Änderungen entspringen einer Verbesserung im Rahmen nationaler Anpassungen und sind begründbar. Die geänderten Daten sind im Datensatz für die Anpassung aller Jahre 2010 ff. zu finden. 
-2. Anpassung aller Jahre 2010 ff. 
-Mit den konsolidierten Wetter- und Flächendaten sind keine Jahre vor 2010 modellierbar, weil diese Datenmenge nicht verfügbar ist.

-With the use of the 2019 GB method [(EMEP/EEA, 2019: EEA Report No 13/2019 EMEP EEA air pollutant emission inventory guidebook 2019, Copenhagen, 2019; URL: https://www.eea.europa.eu/publications/emep-eea-guidebook-2019/part-b-sectoral-guidance-chapters/2-industrial-processes/2-a-mineral-products/2-a-5-a-quarrying/view)], a Tier 2 method is available that can reflect different national conditions. In particular, this concerns input variables on humidity and wind speed, which are differentiated into twelve regions.+With the use of the 2019 GB method [(EMEP/EEA, 2019: EEA Report No 13/2019 EMEP EEA air pollutant emission inventory guidebook 2019, Copenhagen, 2019; URL: https://www.eea.europa.eu/publications/emep-eea-guidebook-2019/part-b-sectoral-guidance-chapters/2-industrial-processes/2-a-mineral-products/2-a-5-a-quarrying/view)], a Tier 2 method is available that can reflect different national conditions. 
 + 
 +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. 
 + 
 +The temporal resolution of the regional parameters has limitations: no weather data reports are available on a station basis before 2010, so no area information from the Corine land cover before 2010 is used (consistent data sets). In addition, information from CLC category 131 (Mineral extraction sites [(Copernicus 2019: CLC-classes; URL: https://land.copernicus.eu/user-corner/technical-library/corine-land-cover-nomenclature-guidelines/html/index-clc-131.html)]) had to be adjusted for areas of active open-pit lignite mines.

-As provided for in the GB model, we use AD in the split hard rock, sand and recycled material. These AD are taken from association information because the national statistics are not complete [(European Industry Association data are published annually at https://uepg.eu/pages/figures.
