Mapeo y análisis multitemporal de carbono negro y gases de efecto invernadero con imágenes satelitales

Abstract

Climate change is one of the most pressing challenges facing modern society, largely driven by greenhouse gases (GHGs) and black carbon, both known for their ability to disrupt climate systems and impact public health (Zhao et al., 2023). These pollutants interact with regional topography, influencing critical factors such as land use, vegetation, humidity, temperature, and air circulation patterns. This study proposes the use of multitemporal satellite imagery and Geographic Information System (GIS) tools to spatially map and analyze these pollutants between 2019 and 2024, using data from the Copernicus and NASA programs. The analysis focuses on both national scale and the department of Cundinamarca, identifying patterns and temporal variations in black carbon and GHG concentrations. The results aim to facilitate the interpretation and analysis of environmental data. The Institute of Hydrology, Meteorology and Environmental Studies (IDEAM) is a public entity under Colombia’s Ministry of Environment and Sustainable Development, with administrative autonomy, legal status, and independent assets. Its mission is to generate knowledge and provide reliable, consistent, and timely scientific and technical information on Colombia’s natural resources and environment. This information is essential for shaping environmental policies and supports decision-making across the public and private sectors, as well as among the general public. IDEAM is also responsible for monitoring, classifying, and zoning land use nationwide, providing a technical basis for territorial planning and management. By 2026, IDEAM aims to be recognized nationally and internationally as a model institute that delivers key information for sustainable development and climate change mitigation.
