Instrument

NH3 CIMS
Ammonia Chemical Ionization Mass Spectrometer

The Ammonia (NH3) Chemical Ionization Mass Spectrometer (CIMS) is an airborne, in situ spectrometer operated by NOAA. It employs the CIMS measurement technique to detect NH3 in the atmosphere. It has a time resolution of 1 to 5 seconds, depending on the measurement requirements of the field campaign. NH3 CIMS has a precision of 35 to 80 pptv for 1-second data and an accuracy of 25%.
