The Ammonia (NH3) Chemical Ionization Mass Spectrometer (CIMS) is an airborne, in situ spectrometer operated by NOAA. It uses the CIMS 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. The NH3 CIMS has a precision of 35 to 80 pptv for 1-second data and an accuracy of 25%.
