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，它是酸的中和剂。氨也是固定氮通过大气和生物圈循环的重要物种，而固定氮是生命的重要营养物质。然而，由于氨对酸、水和表面的亲和力，对氨的可靠测量已被证明是困难的。该项目的目标是为1989年冬季NOAA（美国国家海洋和大气管理局）比对计划现场部署乔治亚理工学院真空紫外/光碎片激光诱导荧光（VUV/PF-LIF）氨传感器。这项相互比较工作目前定于1989年冬季在科罗拉多州博尔德附近进行。这种相互比较的主要目的是测试和评价能够测量接近大陆背景水平的环境氨浓度的仪器的性能特征。

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.
