Webinar Introductorio: Un Vistazo a Cómo la NASA Mide la Contaminación del Aire logo. Image: NASA

¿Le gustaría saber cómo acceder y visualizar imágenes satelitales de la NASA? La reciente disminución de la contaminación atmosférica a nivel mundial debido al bajón económico ha capturado la atención del mundo entero y recibido mucha cobertura mediática. Inspirándose en ello, esta serie de dos webinars imparte conocimiento fundamental para novatos y sirve de curso de repaso para los demás. Ud. aprenderá cuáles son los contaminantes que se pueden medir desde el espacio, cómo los satélites hacen estas mediciones, lo que se debe hacer y no se debe hacer al momento de interpretar datos satelitales y cómo descargar y crear sus propias visualizaciones. 

Objetivos de Aprendizaje:

  • Al finalizar esta capacitación, los/las participantes podrán:
  • Nombrar los contaminantes que pueden ser observados por satélites de la NASA
  • Encontrar y descargar imágenes para NO2 y aerosoles/partículas
  • Describir las capacidades y limitaciones de las... read more
Introductory Webinar: An Inside Look at how NASA Measures Air Pollution logo. Image: NASA
Participants will learn which pollutants can be measured from space, how satellites make these measurements, the do’s and don’ts in interpreting satellite data, and how to download and create your own visualizations.
 
Learning Objectives
By the end of this training, attendees will be able to:
 
  • List the pollutants that can be observed by NASA satellites
  • Find and download imagery for NO2 and aerosols/particles
  • Describe the capabilities and limitations of NASA NO2 and aerosol measurements
Air quality monitoring with Sentinel-5p. Image: RUS

During this webinar, you will be introduced to Sentinel-5p data and learn how to process the data using the BEAT software. We will demonstrate how using basic analysis, Sentinel-5p data can be used to monitor air quality at regional and global scale.

The webinar is structured as follow:

  • Study area
  • Remote sensing background
  • Introduction to Sentinel-5P
  • RUS service
  • Exercise

The training will focus on using the BEAT Open Toolbox to process Sentinel-5P data for different trace gas and aerosol in the atmosphere. Attendees will also gain knowledge on Sentinel-5P products and use the data to create world maps of the pollution. They will follow polluting events (such as rain-forest fires, pipeline emissions) with the daily measurement and global coverage of Sentinel-5P. Eventually special focus will be given on quantifying the pollution in a city during distinct periods of the year.

Participants will access a Virtual Machine from their own laptop, to exploit the open-source toolboxes available in the RUS environment and download and process Sentinel-5P data.

During this webinar, participants will learn how to access the RUS environment allowing to download, process, analyse and visualize the free data acquired by the Copernicus satellite and you will be introduced to Sentinel-5P data, especially Level 2 Products. Participants will then discuss the structure of the netCDF files used to distribute the data and we will explore them using the well-known Python library xarray. In addition, participants will learn how to generate Level 3 products using HARP for a multi-temporal evaluation of NO2. The analysis will focus on Northern Italy, where NO2 emissions drastically dropped since the beginning of March 2020, as a result of Italy’s lockdown due to Covid-19, leading to a slump of the industrial activity.

The National Aeronautics and Space Administration (NASA), the European Space Agency (ESA) and the Republic of Korea are working together on a global satellite constellation of three space-based instruments that could track global pollution on an hourly basis. These air quality satellites will measure pollutants, including ozone, nitrogen dioxide, formaldehyde and tiny atmospheric particles called aerosols in order to enhance our understanding of air quality and air pollution. To date, air quality satellites have collected data only once a day. These three new instruments will provide hourly, highly detailed and near-real-time data that will improve air quality science and forecasting around the world, in particular around the most densely populated areas of the Northern Hemisphere. 

Collecting data hourly will allow to capture pollution that appears episodically, like rush-hour traffic or a power plant that switches on to meet peak power demands, as well... read more

Sentinel Hub, together with the European Earth Observation programme Copernicus and the European Space Agency, are looking for new and innovative ideas and scripts for Sentinel data processing and visualization. The contest will run until 5 May 2019 and all the entries will be judged by a jury of experts on functionality and usefulness, as well as possible commercial value.

The EU Earth Observation Browser and similar services are made possible through open data policies, which allow everyone to access and use satellite data. Thanks to these policies a wide variety of fields are creating applications for satellite data, however, they need support to make use of the data for these applications. Custom scripts are an easy and quick way to add value to already available data and rapidly test new algorithms.

The Sentinel Hub Custom Script Contest is a remotely run hackathon engaging data... read more

Publishing institution: German Federal Office of Civil Protection and Disaster Assistance

To meet the global challenges, the United Nations adopted several framework agreements, including the Sendai Framework for Disaster Risk Reduction at the Third United Nations World Conference on Disaster Risk Reduction (2015-2030). The framework builds the international reference point for disaster preparedness and focuses on reducing existing and future disaster risks as well as enhancing disaster resilience. In the Sendai framework, seven global targets have been agreed to measure global progress in implementing the framework through quantifiable indicators and to present, compare and evaluate the status and progress uniformly worldwide. The recording of the status and degree of target achievement using the agreed indicators requires the use of various data sources, which must be consistent and comparable in time and space in order to ensure global monitoring.
