Abstract
Nitrogen dioxide (NO2) is very important in the tropospheric chemistry. Short-term NO2 exposure, ranging from 30 minutes to 24 hours, can cause the exacerbation of asthma symptoms, in some cases resulting in hospitalization. Long-term NO2 exposure is likely to have a causal relationship with respiratory effects, based on evidence for the development of asthma. Hampton University (HU) built a Differential Absorption Lidar (DIAL) based on an Optical Parametric Oscillator (OPO) laser which can obtain more accurate measurements of NO2 using three-wavelengths elastic signals. NO2 concentration profiles were obtained using the HU three-wavelength OPO DIAL and these results were compared with simulated data from WRF-Chem model and NO2 profile from Pandora to assess their accuracy.
