ammonia concentrations, nitrogen balance, passive samplersAbstract:
From 2002 to 2004, a monitoring network was operated in <st1:place w:st="on">Hesse</st1:place> to determine atmospheric ammonia concentrations using passive samplers. Primary goal of the measurements was the assessment of a data set which could be used to check the validity of the atmospheric transmission and deposition model. In addition, these data were to provide information about the accuracy and spatial representativeness of such measurements.<o:p></o:p></span></p>

The concentrations of the latter were surprisingly high.<o:p></o:p></span></p>
