Abstract ATM-9503277 Shah, Kathryn P. Columbia University Title: Supersonic Aircraft Emission Signals in Satellite & GCMAM Microwave Maps Aircraft emissions can potentially change the regional and global climate through their greenhouse interaction with reaction with radiation and though their photochemical interaction with ambient atmospheric species such as ozone. Supersonic aircraft exhaust adds water vapor, NOx, CO2, sulfur, soot, and cloud condensation nuclei to high altitudes (20 km) in the stratosphere. Current atmospheric forcing by aircraft emission will no doubt be amplified by the increased supersonic fleet planned by 2015. A microwave radiative transfer model can be enhanced to work with Global Climate-Middle Atmosphere Model (GCMAM) experiments. These GCMAM experiments predicted the atmospheric impacts of water vapor and ozone perturbations from supersonic aircraft emission. The signature of the supersonic ozone and water vapor perturbations can be sought in NOAA satellites' Microwave Sounding Unit (MSU) data based on the GCMAM microwave maps produced by microwave radiative transfer model. The GCMAM microwave maps can also assess the progression of changes at different altitudes during the GCMAM's time integration as compared with actual satellite data. Finally, this would lead into future research investigating the importance of the emission signal relevant to other anthropogenic signals and to natural variability given current and future satellite resolution and sensitivity. This is a Research Planning Grant.

Am-9503277卫星上的超音速飞机发射信号&GCMAM微波地图飞机的排放可能通过它们与辐射的温室相互作用以及通过它们与周围大气物种(如臭氧)的光化学相互作用来改变区域和全球气候。超音速飞机尾气将水蒸气、氮氧化物、二氧化碳、硫磺、烟尘和云凝结核添加到平流层的高海拔(20公里)。计划在2015年前增加超音速机队，无疑将放大目前由飞机排放造成的大气压力。一个微波辐射传输模式可以得到改进，以便与全球气候-中层大气模式(GCMAM)的实验相配合。这些GCMAM实验预测了超音速飞机排放的水蒸气和臭氧扰动对大气的影响。从NOAA卫星的微波探测单元(MSU)数据中可以找到超音速臭氧和水汽扰动的特征，该数据基于微波辐射传输模式产生的GCMAM微波图。GCMAM微波地图还可以与实际卫星数据相比，评估GCMAM时间积分期间不同高度的变化进程。最后，这将导致今后的研究，调查发射信号与其他人为信号相关的重要性，以及考虑到当前和未来卫星分辨率和灵敏度对自然可变性的重要性。这是一项研究计划拨款。
