All other long- lived forcing terms reflect the steady state response of the atmosphere to sustained aircraft NO x emissions of the year 2000, based on methane lifetime changes due

Another impact of non-acyl peroxy nitrates is that they are a possible positive inter- ference to in-situ NO 2 measurements in the upper troposphere because the non-acyl peroxy

We report a new method for the simultaneous in situ detection of nitryl chloride (ClNO 2 ) and dinitrogen pentoxide (N 2 O 5 ) using chemical ionization mass spectrometry (CIMS)..

In summary, the correction procedure when sampling from the 453 and 723 K inlets is as follows: (1) We use the model simulation results in the form of look-up-tables with measured
