The data on the 1 x 1 km emissions of nitrogen oxide are depicted both as a color grid and as an absolute value. The color depiction uses rounded-off numbers.

The polluter-related calculated pollution is depicted to match the presentation of the sum of nitrogen oxide emissions for 1989. These have been determined with the help of the above described dispersion calculations and using a normal distribution approach as described in the TA-Luft.

Since the pollution measurements are taken continuously, those for the current year 1991 could be selected. The nitrogen oxides are presented the measured pollution as annual mean of the sum in the comparison with the results of the dispersion calculations and as nitrogen dioxide to the comparison with the limits. For NO2 the limits IW1 and IW2 of TA-Luft 1986 were set as class values for the delimitation the highest class. They were compared to the reference values I1 (annual mean) and I2 (98 %-value). In comparison to the display in the Environmental Atlas 1985, the limit for the short term load (98-Percentile Map 03.03.10) adapted to the revised TA-Luft 1986.

The interpolation of the isolines resulted per hand. In addition, the respective values are presented BLUME - measurement stations, distinguished according to type the stations.
