Supersonic Aircraft Emission Signals in Satellite & GCMAM Microwave Maps

摘要ATM-9503277 Shah，Kathryn P.哥伦比亚大学题目：卫星GCMAM微波图中的超音速飞机发射信号 飞机排放物通过与辐射反应的温室效应相互作用以及通过与周围大气物种（如臭氧）的光化学相互作用，可能改变区域和全球气候。 超音速飞机的废气会将水蒸气、氮氧化物、二氧化碳、硫、烟尘和云凝结核添加到平流层的高空（20公里）。 毫无疑问，到2015年，计划增加的超音速机队将扩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被增强以与全球气候-中层大气模式（GCMAM）的实验一起工作。 这些GCMAM实验预测了超音速飞机排放的水汽和臭氧扰动对大气的影响。 利用微波辐射传输模式生成的GCMAM微波图，可以从NOAA卫星的微波探测单元（MSU）数据中寻找超音速臭氧和水汽扰动的特征。 GCMAM微波图还可以评估GCMAM时间积分期间不同高度的变化进程，并与实际卫星数据进行比较。 最后，这将导致未来的研究，调查排放信号相对于其他人为信号和自然变异的重要性，考虑到目前和未来的卫星分辨率和灵敏度。 这是一个研究规划补助金。

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.
