The PI plans to examine (1) involvement of natural hydrocarbons for the formation of H2O2 and HCHO in air and (2) liquid phase formation of H2O2 and organic acids in clouds. Specifically, he will conduct continuous measurements of formaldehyde and peroxides in the gas phase, in cloud water, and in precipitation at Whiteface Mountain with concurrent measurements of other key atmosheric trace gases, including O3, CO, NOy, SO2 and selected hydrocarbons and trace elements. The goal is to document the chemistry of individual cloud events and to determine seasonal and air mass specific differences in cloud water chemical composition. Additionally, the PI plans a limited flight program focussing on measuring horizontal and vertical profiles for H2O2 and O3 under clearly defined meteorological conditions in clear and cloudy air, including airborne cloud water collections. He will also add measurements of other photochemically important species such as hydroperoxides and other low molecular carbonyl compounds (aldehydes and ketones) as the initial research program matures.

PI计划检查（1）自然参与 在空气中形成H2O2和HCHO的烃，以及（2） H2O2和有机酸的液相形成。 具体而言，他将对以下方面进行连续测量： 甲醛和过氧化物在气相中，在云水中， 白面山的降水量， 其他关键大气痕量气体，包括O3、CO、NOy、SO2和 选择碳氢化合物和微量元素。 目标是记录 个别云事件的化学成分，并确定季节性 云水化学物质和空气质量的具体差异 混合物. 此外，PI计划有限的飞行计划 重点测量H2 O2的水平和垂直分布， O3在明确定义的气象条件下， 多云空气，包括空中云水收集。 他将 还增加了其他光化学重要物种的测量 例如氢过氧化物和其它低分子羰基化合物 （醛和酮）作为初步研究计划的成熟。
