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.

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，并且是酸的中和剂。 氨也是固定氮循环中的重要物种，固定氮是生命在大气和生物圈中的重要营养素。 然而，由于氨对酸、水和表面的亲和力，氨的可靠测量已被证明很难获得。 该项目的目标是为 1989 年冬季 NOAA（国家海洋和大气管理局）比对计划现场部署佐治亚理工学院真空紫外线/光碎裂激光诱导荧光 (VUV/PF-LIF) 氨传感器。 目前这项比对工作计划于 1989 年冬季在科罗拉多州博尔德附近进行。 此次比对的主要目的是测试和评估能够测量接近背景大陆水平的环境氨浓度的仪器的性能特征。
