A31F:
Advances in Instrumentation and Methods for Atmospheric Chemistry I


Session ID#: 10909

Session Description:
Innovative instrumentation and measurement techniques drive progress in atmospheric chemistry. The last several years have seen tremendous advances in instrumentation for both gas and aerosol phase measurements. Progress has been made in gas phase measurements spanning scales from highly reactive radicals at sub parts per trillion levels to long-lived greenhouse gases at parts per million scales. Innovations in the aerosol phase have included everything from nucleation to coarse mode particles. The advances in methods including spectroscopy, fluorescence, mass spectrometry, gas chromatography and many others have revolutionized our understanding of atmospheric chemistry.  Refinements in the accuracy and precision of well-established techniques have also advanced the field.  This session invites submissions describing recent advances in analytical instrumentation and methods for the study of atmospheric chemistry in both field and laboratory settings. We are seeking to promote discussion of new techniques and innovative methods, as well as create an environment conducive to collaboration.
