Field Deployment of a VUV/PF-LIF Ammonia Sensor as Relates to the NOAA Hosted NH3 Instrument Intercomparison Program

氨是低层大气中的一种重要气体。 它 在颗粒的形成中起着至关重要的作用， 酸的中和剂。 氨也是一种重要的 物种在固定氮循环，这是一个至关重要的 通过大气层和生物圈为生命提供养分。 然而，氨的可靠测量已被证明是困难的。 因为它对酸、水和 表面。 该项目的目标是实地部署 格鲁吉亚理工学院真空紫外/光致碎裂激光诱导 荧光（VUV/PF-LIF）氨传感器1989年冬季 国家海洋和大气管理局 相互比较方案。 这种相互比较的努力是 目前定于1989年冬季在科罗拉多的博尔德附近。 这种相互比较的主要目的是测试和 评估仪器的性能特征， 测量接近背景的环境氨浓度 大陆水平。

Ammonia is an important gas in the lower atmosphere. It plays a crucial role in the formation of particles and it is a neuturalizing agent of acids. Ammonia is also an important species in the cycling of fixed nitrogen, which is a vital nutrient for life, through the atmosphere and biosphere. However, reliable measurements of ammonia have proven difficult to obtain because of its affinity for acids, water, and surfaces. The goal of this project is the field deployment of the Georgia Tech Vacuum UV/Photofragmentation Laser-Induced Fluorescence (VUV/PF-LIF) ammonia sensor for the Winter 1989 NOAA (National Oceanic and Atmospheric Administration) Intercomparison Program. This intercomparison effort is currently scheduled for Winter 1989 near Boulder, Colorado. The primary purpose of this intercomparison is to test and evaluate the performance characteristics of instruments capable of measuring ambient ammonia concentrations near background continental levels.
