该提案要求提供资金,对对流层臭氧进行高精度的氧同位素测量,以便更好地了解对流层臭氧的化学性质。 所有三种氧同位素(O-16、O-17和O-18)都将使用稳定同位素比质谱法对大气臭氧样品进行测量。 建议进行测量,以解决臭氧迁移和转化率的程度和可变性、远程海洋臭氧化学以及平流层臭氧注入对流层的程度。
英文摘要
This proposal requests funds to pursue high precision oxygen isotopic measurements of tropospheric ozone in an effort to better understand tropospheric ozone chemistry. All three oxygen isotopes (O-16, O-17, and O-18) will be measured on atmospheric ozone samples using stable isotope ratio mass spectrometry. Measurements are proposed to address the extent and variability of ozone transport and transformation rates, remote marine ozone chemistry, and the magnitude of stratospheric ozone injections into the troposphere.
