This project's main objective is to make accurate photoabsorption cross sections of molecular nitrogen and oxygen in the wavelength region 80-105 nm. This region absorbs solar radiation between 100 and 240 km, and is the primary source of physical processes such as excitation, dissociation, and ionization. To completely understand basic principles of atmospheric processes, the PI will study how the solar flux is absorbed by thermospheric molecules. He will accurately determine photoabsorption cross sections in the laboratory under conditions representative of the atmospheric region where the absorption occurs.

该项目的主要目标是在80-105 nm波长范围内精确测量氮分子和氧分子的光吸收截面。 这个区域吸收100到240公里之间的太阳辐射，是激发、离解和电离等物理过程的主要来源。 为了完全理解大气过程的基本原理，PI将研究太阳通量如何被热层分子吸收。 他将在实验室中准确地确定在吸收发生的大气区域的代表性条件下的光吸收截面。
