Resumen
Descripción
The remote sensing methods for understanding physical phenomena are being used since the last 50 years. Satellite- based sensors and ground-based sun photometers provides quantitative and qualitative knowledge about the composition of elements within the Earth’s atmosphere. One actual problem is the changes on the climate of different regions of the Earth; one of them is related to aerosol climate forcing. Improvement in measurement-based systems is necessary to identify remaining issues and improve quantification of aerosol effects on climate. Also the improvement in modeling is necessary to confidently extend estimates of forcing to prior times and to project future emissions. Achieving these capabilities will require a synergistic approach between observational systems and modeling. This paper describes how the study and analysis of satellite-based and ground-based measurements can be used to develop an innovative method, based in the existent methods to calculate some optical properties that will help in characterization of the dominant temporal aerosols found in and around the city of Guadalajara in Mexico, based on previous algorithms. The quantifiable knowledge about the temporal and regional aerosols’ optical properties will contribute to future investigations related to their quantitative effects on atmospheric processes in this region.
