Study of the use of an infrared telescope for astronomical observation as a means to measure global warming substances

Research grant

Project Description

Examination of a technique that uses an infrared telescope for astronomical observation as a means to measure the concentrations of carbon dioxide, methane and other substances in the atmosphere that are causes of global warming. The objective is to confirm this method so that ground-based observatories of global warming substances can be set up in South America and other as-yet uncovered regions. In addition, the project also seeks to establish techniques that can be applied to the analysis of astronomical observation data from observatories around the world, in order to prepare the basis for the setting up of an observational network for the Earth's atmosphere that uses telescopes.
