• Sommario/riassunto: Almost all of the breakthroughs in understanding the atmosphere have been initiated by field observations, using a range of instrumental techniques. Developing or deploying instruments to make further observations demands a thorough understanding of the chemical and spectroscopic principles on which such measurements depend.Written as an authoritative guide to the techniques of instrumental measurement for the atmospheric scientist, research student or undergraduate, Analytical Techniques for Atmospheric Measurement focuses on the instruments used to make real time measurements of atmo
