Settlement areas and transport infrastructure (Division A01)
Condition variableSubvariableUnitCondition 2015Condition 2018Condition 2021
The values of the condition variables present the yearly arithmetic average for the respective ecosystems, if not definied differently by the measurement unit.
1: According to 39. BimSchV AOT (Accumulated Ozone Exposure) 40 is the sum of differences between ozone values above 80 micrograms per cubic metre over a specific period, based on hourly concentrations between 8 an 20 CET.
2: Due to a methodological change in the underlying data source (increased spatial resolution) the changes between the time steps cannot be interpreted.
