Greenhouse Gas Satellite Missions Portal
This Portal aims to provide a comprehensive and up-to-date list of all current and planned satellite missions with the ability to measure greenhouse gases. This includes those planned and operated by both public and commercial organisations, as well as NGOs. The Portal is based on data from the CEOS MIM Database and aims to support the analysis and planning of GHG measurement continuity by providing visualisation and export capabilities such as measurement timelines and tables of missions and instruments. The CEOS Database team will undertake to ensure the Portal is both comprehensive and current so that it may be applied with confidence for these studies.Missions are categorised under three headings according to their purpose and capabilities.
The Portal aims to support coordination and planning of initiatives world-wide that are seeking to exploit these valuable data in support of emission reduction measures. It should assist those researching which data sources may be suitable for their information needs and can provide a basis for the high-level coordination needed among space agencies and other data providers to ensure that society has continuity of these key measurements into the future in support of our long-term climate data records and processes such as the Global Stocktake of the Paris Agreement.
At the heart of the Paris Agreement is an understanding that governments will develop and meet GHG emission reduction targets. The global community recognises the need for urgent and collective actions on the mitigation of GHG emissions if we are to limit global warming. Data and knowledge of global GHG emissions, trends and sources will become increasingly important to support national and international climate policymaking. Transparent reporting processes will demand more and better data to satisfy society's needs, and satellite Earth observation (EO) has the potential to play a critical role to support policymakers at the intersection between science and action. EO satellites are increasingly capable of monitoring GHG emissions with precision, accuracy, resolution, and coverage needed to support policymakers at all levels, from the sub-national and national level for the establishment and operation of national GHG inventories, through to the global reconciliation and accounting processes that will seek to match aggregated national reports with the latest global observations. Refer to the CEOS Global Stocktake Portal for more information on relevant datasets.
The GHG Constellation Builder linked below has been created to help users identify a constellation of satellites which meets their specific requirements. Simply make a copy of the spreadsheet and use the filters to tailor a solution.
This resource is a product of the overall Greenhouse Gas Roadmap being implemented by CEOS and CGMS agencies.

Satellite GHG Data Making an Impact
Observe Daily Pulses in CO2 EmissionsCO2
NASA's Earth Observatory presents a global model of
CO2 between January and March 2020, using data from MODIS and VIIRS
satellite instruments. Circulation of the Earth's atmosphere spreads these
CO2 emissions across the continents and oceans. The model was created
using NASA's Goddard Earth Observing System (GOES), a supercomputer-powered
weather model used to simulate atmospheric processes. GOES uses satellite data
including that from NASA's Terra and NOAA's Suomi-NPP satellites.
The map pulses daily due primarily to the diurnal behaviour of both
fires and plant life. Fires tend to flare up during daytime and die down at
night - and plants absorb CO2 during the day then release it during
the night.
The full CO2 visualisation can be downloaded from NASA's
visualisation studio.

Pipe Leak in the UK Detected by GHGSatCH4
GHGSat satellites observed a methane plume over Cheltenham, UK,
originating from a pipe leak near a landfill site. Researchers from the UK's
National Centre for Earth Observation (NCEO) and the University of Leeds spotted
the emission while using GHGSat data in support of the UK DECC (Deriving
Emissions linked to Climate Change) Network.
GHGSat tasked their constellation to make five further measurements
which observed methane emission rates of between 200 and 1,400 kg per hour.
These observations were validated by in situ measurements and then used to
inform the attributor who promptly addressed the leak. This feat marked the
first time that methane emission in the UK had been detected from space and
mitigated.

Cairo Farmlands Absorb CO2
CO2
JAXA's GOSAT mission monitored crops on farm lands surrounding
Cairo, Egypt consumed CO2 by observing solar-induced chlorophyll
fluorescence (SIF). SIF is an innovative measurement that serves as a proxy for
plant photosynthetic activity. Crops and other plants absorb sunlight during
photosynthesis, and emit some of the unused energy as a red glow, known as SIF.
Daily atmospheric CO2 changes can be monitored by
combining data from the GOSAT and Sentinel-5P satellites with surface wind data
and emission inventories. GOSAT observes partial column densities of
tropospheric carbon dioxide (XCO2) over cities and provides
CO2 enhancement between the lower and upper atmosphere.
The image shows that in the summer growing season, low
CO2 levels were detected over Cairo, correlated with high SIF.

Global Methane Monitoring with KayrrosCH4
European company Kayrros has developed a global methane
monitoring tool that leverages data from the Sentinel-5P and EMIT missions, with
further data available from Sentinel-2 and -3, GOES-R, EnMAP, and PRISMA. The
tool features a time series of large methane emissions with asset and source
classification.
ESA's Sentinel-5P observations are supplemented by missions like
Sentinel-2 and -3 with higher resolution and narrower swaths, using the 'tip and
cue' measurement approach, which uses a facility scale plume monitor to hone in
on a GHG source as broadly identified by a wide area mapper.
Kayrros studies indicate that there are around 100 large methane
leaks at any time around the world, and approximately half of them are
attributable to the oil, gas and mining sectors.
