Aerosol Air Mass Distinctions over Jalisco using Multi-Angle Imaging Spectroradiometer

Aerosols play an important role in global climate change.[Reference new IPCC report]. These particles directly affect the radiative budget due to absorption and scattering of radiation. Additionally, aerosols are known to alter various ecosystems, cloud formation and properties, precipitation, air quality and visibility. They also have well-documented impacts on human health. In the last 30 years, progress has been made in remote sensing retrievals of aerosol distribution and properties, using different satellite sensors as well as ground-based sun photometer instruments, monitoring programs, and intensive field campaigns around the world. This paper describes how the study and analysis of satellite-based (CALIPSO) measurements and the Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) model make it possible to identify some of the predominant tropospheric aerosols, black carbon and organic carbon. We present the black carbon and organic carbon aerosols and their optical properties by season, within the region of Jalisco México.ITESO, A.C.Universidad de Guadalajar

Model for Identification of Seasonal Aerosols within the Environment for a Particular Region using Remote Sensing Data

Remote sensing methods for the understanding of physical phenomena has been used since the last 50 years. Satellite- based sensors and ground-based sun photometers provide quantitative and qualitative knowledge about the composition of different elements that exists within the atmosphere of the Earth. One of the current tasks relates to understanding the changes of the climate on different regions throughout the planet, where a particular problem 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 dominant temporal aerosols.ITESO, A.C.Universidad de Guadalajar

Satellite Measurements of the Angstrom Exponent using an Innovative Mathematical Method to Identify Seasonal Aerosols

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.ITESO, A.C.Universidad de GuadalajaraNASA Goddard Space Flight Cente

Development of a Novel Algorithm to Calculate the Optic Properties of Temporal Aerosols Through Remote Sensing Data Measurements: Prospective Study

Satellite’ sensors as well as ground-based sun photometers instruments surface are utilized gather data about the quantitative composition of components in the Earth’s atmosphere. The relationships among these components produce effects in different phenomena, like regional climate change. Aerosols, consisting of particles from 0.01 to 10 m, are atmosphere components, whose effects are still poorly understood. Through Remote Sensing, it is possible to classify them and gain information about their role in different atmospheric processes: low visibility, solar energy balance, cloud formation and increases or decreases of the quantity of precipitation. This paper describes how the study and analysis of satellite-based and ground-based measurements can be used to develop and validate a novel procedure to calculate the optical properties of temporal aerosols found in and around Guadalajara, based on previous algorithms:, to determine the aerosol size distribution function, scattering phase function, single scattering albedo, complex refractive index and asymmetry parameter. 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. These effects include: alteration of weather and climate, change of the tropospheric temperature, contribution to environmental ills, the formation and properties of the clouds, effects on the ecosystems, local solar energy balance, and the impacts on human health.ITESO, A.C.ITESMNASA Goddard Space Flight Cente
