This new type of satellites capable of measuring CO2 emissions to the nearest kilometer and pinpointing their origin.
One of these nanosatellites, PICASSO, carries
remote sensing technology developed which will be used to undertake
measurements in the upper layers of Earth’s atmosphere.
PICASSO stands for Pico-Satellite for Atmospheric and Space Science Observations and it’s the first CubeSat nanosatellite mission of the Royal Belgian Institute for Space Aeronomy.
Weighing only 3.5kg, it carries two measuring instruments for
atmospheric research: A Visible Spectral Imager
for Occultation and Nightglow (VISION) and a system to conduct plasma
measurements in the ionosphere, the Sweeping Langmuir Probe (SLP).
This project of analysis and collection of satellite data will be
carried out over 5 years. The aim is to obtain as much precise information as
possible on the quantification of gases in the air.
We will be able to know exactly the real CO2 emission by country, cities and the origin of gases (if it’s anthropogenic or natural).
Thanks to this initiative, more and more surveillance systems will be
sent into space over the next few years, which will help develop the market for
remote sensing solutions.
Cimel will be part of this development by bringing additional data thanks to its photometers and LiDARs to help calibrate and validate data from satellites.
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.
Aerosols, these tiny particles of the lower
atmosphere, are one important component of atmosphere affecting climate
(radiative effects, water cycle) and air quality.
For characterizing and monitoring aerosols,
water wapor and clouds, LOA and Cimel, in collaboration with NASA’s GSFC,
developed the robotic solar photometer for the AERONET network in the early
1990s. The meeting between CNRS and NASA researchers and the industrial company
Cimel led to the definition of an automatic, robust, autonomous solar
photometer that transmits its data by radio, providing AOD and particle size in
real time. In 1998, the French component (PHOTONS) was awarded the INSU
Observation Service label.
Cimel is NASA – AERONET’s exclusive supplier of automatic Sun Sky Lunar photometers (CIMEL CE318-T) operating in near real time and providing aerosol optical and columnar microphysical properties.
