Programa de Estaciones Meteorológicas del Bachillerato Universitario

Coordinador General – Dr. Michel Grutter de la Mora

El Programa de Estaciones Meteorológicas del Bachillerato Universitario (PEMBU) es uno de los proyectos institucionales de la UNAM que vincula las funciones sustantivas de docencia e investigación, las dependencias y los niveles educativos de la UNAM, en los que participan conjuntamente los Subsistemas del Bachillerato y de la Investigación Científica.

La misión del PEMBU consiste no solo en el acopio de datos meteorológicos, sino también contribuir al conocimiento de las condiciones locales de la atmósfera en la Ciudad de México. El PEMBU busca que los estudiantes tengan oportunidad de integrar los conocimientos adquiridos en diferentes materias y aplicarlos al análisis y discusión de problemas de la ciudad. Asimismo, tiene como meta poner a disposición de maestros, una base de datos de variables meteorológicas con fines de investigación y docencia.

Red Universitaria de Observatorios Atmosféricos

Coordinador General – Dr. Michel Grutter de la Mora

El registro continuo de variables atmosféricas nos permite estudiar la variabilidad de parámetros meteorológicos y ambientales en diferentes escalas de tiempo. La Red Universitaria de Observatorios Atmosféricos (RUOA) impulsa la investigación y la docencia a través de la interdisciplina y la cooperación institucional, estableciendo sitios de medición con procedimientos predeterminados con un alto control de calidad en cuanto a la operación de sensores y manejo de datos. El carácter académico de esta red permite el intercambio de las experiencias para mejorar los lineamientos y la difusión de la información generada con la política de datos abiertos.

Red de Carbono Negro

Coordinador General – Dr. Oscar Peralta Rosales

El carbono negro proviene principalmente del uso de leña a nivel doméstico y de las quemas agrícolas, seguido de los automotores a diésel.
La Red de Carbono Negro es un esfuerzo entre instituciones por establecer un sistema de mediciones continuas de carbono negro en toda la República Mexicana. Con los valores de carbono elemental se determina el coeficiente de absorción de masa, esta determinación permitirá tener el factor de corrección a las lecturas de carbono negro obtenidas con etalómetros y de esta manera realizar los ajustes de concentraciones en cada entidad donde se está monitoreando actualmente, dando validez a la información generada por la Red de Carbono Negro.

PAPILA Project

Coordinado en México: Dr. José Agustín García Reynosa

The overall objective of the PAPILA project (Prediction of Air Pollution in Latin America and the Caribbean) is to establish a sustained network of partners with complementary expertise that develop and implement an analysis and forecast system for air quality with downscaling capability for Latin America and the Caribbean region (LAC region), and to assess the impact of air pollution (background and peaks) on health and on the economy. This system will help decision-makers improve air quality and public health, and avoid the occurrence of acute air pollution episodes, particularly in urban areas.

Participants: José Agustín García, Arón Jazcilevich, Michel Grutter, Luis Gerardo Ruiz Suárez, Wolfgang Stremme, María del Carmen Calderón, Benjamín Martínez, Arturo Quintanar, Graciela Binimelis de Raga

The project combines an ensemble of state-of-the-art models, high-resolution emission inventories, space observations and surface measurements to provide near real time forecasts and analysis of regional air pollution in the LAC region. To reach this objective, the project will bring together an interdisciplinary team of scientists from Europe, Latin America (Argentina, Bolivia, Brazil, Chile, Colombia, Mexico, Venezuela) and the Caribbean (Puerto Rico), and foster synergies between the groups involved in research and service activities. The project will co-develop with users and other stakeholders several products and services of importance for the LAC region. An important objective of the project is to make use of complementary competence to develop innovative ideas, to established sustained partnerships between research groups, to transfer information to the public, to develop educational activities and to create a dialogue with interested stakeholders. Societal impacts, specifically on human health, on crop production, on ecosystems, on the mountain snow cover and on the hydrological cycle as well as the economic benefits of mitigation policies will be assessed. Finally, the planned activities will provide the basis for sustained capacity building actions.

 

Specific Objectives: The Air Quality Analysis and Forecast System (Figure 1) that will be produced at the completion of the Papila Project will include: (a) a real-time state-of-the-art multi-model quasi-operational air quality prediction system that will forecast the four dimensional distribution of air pollutants (reactive species and particulate matter) and provide related health indices, (b) a real-time (quasi-operational) chemical data system that collects and processes observations of air pollutants; (c) a state-of-the-art data assimilation system that will provide best estimates of the atmospheric chemical state via integration of Earth observations (specifically space observations) in chemistry transport model predictions; (d) an emission inventory based on direct “bottom-up” estimates of anthropogenic sources and on “top-down” inverse modelling methodology (following the efforts undertaken by Andrade et al., 2016), (e) dissemination platforms that will release daily “chemical weather” forecasts with quantified uncertainties, and (f) exchanges and transfer of results to national and international agencies. We propose to use (a) an ensemble of air quality prediction models that account for the complex coupling between dynamical, physical and chemical processes in the atmosphere, (b) different data assimilation schemes that optimize the model forecasts, and (c) a comprehensive validation process based on a statistical comparison of the forecasts with surface measurements of chemical species (Dennis et al., 2010). Particular problems of great interest in the Latin American region are the strong anthropogenic emissions of primary pollutants in megacities (hotspots), emissions in the Amazon of biogenic and pyrogenic species (Guenther et al., 2006), the transport of chemical species in the complex topography of the Andes, and the deposition of black carbon on the cryosphere of the high mountains (Molina et al., 2015).

The modelling and analysis system to be developed by the Papila Project will be used:

  • To provide daily deterministic and probabilistic air quality predictions and related air quality health indices in Latin America and the Caribbean region (LAC region) with spatial resolutions that will be increased in densely populated areas and other hotspots (grid nesting, statistical downscaling, kriging).
  • To determine and release forecasts of regional distributions of primary chemical species (NOx, CO, VOCs, SO2, particle matter (PM) including dust and black carbon), of secondary species (ozone, sulphate, secondary organic aerosols, etc.) and health indices.
  • To study the expected changes in future air quality in response of various forcings such as changes in the emissions due to urbanization and industrialization, and climate change.
  • To estimate the immediate impacts (e.g., acute human health effects, crop damage) and long-term effects (e.g., chronic health impacts, deposition on the biosphere, climate impacts) of air pollution
  • To support the design of air pollution mitigation strategies.
  • To support educational activities related to air pollution and climate change.
  • To develop a sustained capacity building effort and take the opportunity of mutual exchanges to train students and junior scientists from LAC and European countries

European and Latin American research and service institutions will team up through the proposed RISE project, and use their complementary expertise to create synergies on questions related to model development and evaluation, analysis of observational data, and air quality forecasts. This cooperation will be greatly facilitated by the deployment of secondments in Europe and Latin America, by technical workshops and by the participation of the partners in educational activities. The training of early-career scientists and stakeholders from the LAC region will be a key aspect of the Papila project. It will enable them, through their visits in European Laboratories, to become familiar with existing forecast systems and to contribute to their development. The goal is to improve their local and regional air quality modelling capabilities as well as their operational air quality forecasts in their respective Latin American countries. It is also to transfer knowledge, methodologies and tools, and to provide to the staff involved the opportunity to improve skills and career opportunities.
