With growing concern due to climate variation, it is important to create measurement systems to monitor the presence and concentration of elements, molecules and particulates in the atmosphere. This team proposes the design of a low-power solar spectrograph that will measure the relative intensity of H2O Fraunhofer lines (absorption lines) in the atmospheric solar spectrum. Through the design of a durable weather-resistant system, long-term measurements of Fraunhofer lines will be collected at accessible or remote locations to monitor the changes in atmospheric gas concentrations.
