Earth Observation Satellites & Ground Monitoring Solutions – an essential synergy for Air Quality and Climate Change
April 30, 2020
Atmospheric monitoring and climate analysis are strategic missions in order to improve the understanding of air quality dynamics and climate change evolutions. This in turn is a pre-requisite for providing reliable information reports with real data measurements and to help decision makers and end-users to understand the impacts and causes of air pollution with atmospheric impacts and to act upon it.
Satellite data is key for atmospheric and climate monitoring by providing a continuous and global view of the Earth parameters. These data are essential inputs for forecast models by improving their accuracy.
By combining satellite observations with models of the atmosphere and measurements from ground-based instruments, like Cimel Remote Sensing Solutions, it is possible to measure accurately and forecast aerosols (particles suspended in the air), as well as quantify gases level (ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide…) and several other kind of environmental parameters (planetary boundary layer, water leaving reflectance for Ocean color, solar radiation, water vapor, atmospheric concentration profiles PM2.5/PM10…).
Cimel solutions keep working continuously and automatically, to help the calibration of satellite instruments and validate their data. Furthermore, Cimel is always active to support the various research activities from the worldwide scientific community.
In this video, different aerosols are highlighted by color, including dust (orange), sea salt (blue), nitrates (pink) and carbonaceous (red), with brighter regions corresponding to higher aerosol amounts.
MSc Atmospheric Environment: international master degree
A 2-years program graduating a Master of Science in physics or chemistry of the atmosphere, at the highest level aiming to give intendants a strong background in:
Physical and chemical properties of the atmosphere from the molecular to the global scale,
Analytical sciences applied to airborne environment,
Recent research activities on air pollution and climate changes.
The international Master « Atmospheric Sciences » is supported by the french Laboratory of Excellence CaPPA which involves large complementary research projects gathering together partner teams with strong scientific qualifications. It leads top-level research activities thanks to the diversity of researchers’ disciplines and its promising research topics.
Training is dedicated to students in physics and chemistry having validated 4 years of study (Master 1st year / Bachelor / 240 ECTS-credits), wishing to follow a specialization in atmospheric sciences to get a strong background in theory and practical works.
A visit to every laboratory involved in the Labex CaPPA is organized, helping students to identify the research topic they want to specialize in.
Strengths of the training
Students are immersed in an international environment and all courses are delivered in English.
Students from more than 14 nationalities attended to our master since 2013.
Approximately half of fire emissions in the US are from Northwestern wildfires and half are from prescribed fires that burn mostly in the Southeast US. Wildfires burn slightly more fuel and therefore have overall larger emissions, but prescribed fires dominate the area burned and the number of fires. FIREX-AQ will investigate both wild and prescribed fires. Wildfires generally result in exposures with larger pollution concentrations over larger areas, and cause both local and regional air quality impacts. Their emissions are often transported thousands of miles and can impact large regions of the US at a time. Prescribed fires are usually smaller and less intense than most wildfires but occur more frequently and throughout the whole year. They are usually ignited during periods that minimize population expose and air quality impacts, but can cause regional backgrounds to increase, are generally in closer proximity to populations, and are responsible for a large fraction of the US PM2.5 emissions.
This summer, NOAA and NASA are teaming up on a massive research campaign calledFIREX-AQ that will use satellites, aircraft, drones, mobile and ground stations to study smoke from wildfires and agricultural crop fires across the U.S.
Objective: To improve understanding of wildfire and agricultural fire impacts on air quality, weather, and climate.
Cimel provides a CE376 micro-LiDAR as well as its network of CE318-T photometers through AERONET. These solutions will provide detailed measurements of aerosols emitted from wildfires and agricultural fires to address science topics and evaluate impacts on local and regional air quality, and how satellite data can be used to estimate emissions more accurately.
Paris declares itself in a “state of climatic emergency”
July 9, 2019
The City of Paris has adopted the creation of an “IPCC” (Intergovernmental Panel on Climate Change), which will bring together experts (climatologists, urban designers, sociologists, etc.). They will be able to be consulted and play a “constant role in the implementation of climate policies”.
Like many world cities or more recently the Parliaments of the United Kingdom and Ireland, the City of Paris has declared itself in a “state of climatic emergency“. This decision was taken during a vote in the Paris Council on Tuesday, July 9. We must “meet the objectives of the Paris Agreement” adopted in December 2015, argued the assistant in charge of the Environment to the mayor of Paris, Célia Blauel.
Creation of an “IPCC Paris”
During the session, the City of Paris adopted the creation of an “IPCC Paris” which will bring together experts (climatologists, urban designers, sociologists…). They will be able to be consulted and play a “constant role in the implementation of climate policies”, added Célia Blauel.
A few months before the municipal elections, the mayor of Paris Anne Hidalgo and her entourage have not ceased to multiply ecological projects: after the pedestrianisation of the roads on the banks, the Paris City Hall has, among other things, multiplied projects in favour of a complete greening of the streets and squares of the capital or announced the creation of “urban forests” in the middle of the city to fight against global warming and the effects of pollution.
