Observing and understanding our carbon footprint has never been more crucial. As the catastrophic impact of climate change continues to unfold, comprehensive and accurate carbon observing systems offer an essential tool for mitigation strategies and conservation. Delving into the milestones achieved in the development of these systems paints a fascinating picture of scientific integrity and innovation.
The Necessity of Carbon Observing Systems
In the context of growing concerns about greenhouse gas emissions, particularly those derived from fossil fuels, carbon observations have become necessary today than ever. They not only quantify sources and sinks of carbon dioxide but also play a vital role in monitoring the effects of climate change mitigation policies by organizations such as United States Environmental Protection Agency and California Air Resources Board.
Advanced carbon observing systems provide reliable and globally representative data on atmospheric CO2 concentrations, thereby aiding in understanding the carbon cycle’s intricacies. Such data directly aids in assessing contributions towards global warming potential and led to initiatives like emissions trading for a low-carbon economy.
Beyond this, these systems help detect methane emissions, a potent greenhouse gas with about 25 times the heat-trapping capability of CO2. This monitoring is critical to minimize global warming impacts as declared by Intergovernmental Panel on Climate Change.
To appreciate how far we have come in this field, let’s take a look at early efforts to measure CO2.
Early CO2 Measurements: 1950s-1960s
In the late 1950s, direct measurements of atmospheric carbon dioxide were initiated under Charles Keeling’s keen supervision. The work was undertaken at Mauna Loa Observatory in Hawaii and offered initial references for atmospheric CO2 monitoring.
Known as the Keeling curve, it became the longest-running record of atmospheric carbon dioxide, painting a troubling picture of our planet’s health. From about 315 parts per million (ppm) in 1958, levels have soared past 415 ppm in recent times. These pioneering efforts in CO2 measurement have profoundly shaped our knowledge – and response to – global climate change.
A decade later, with the reflections of Earth from the moon recorded by the Lunar Trailblazer, NASA delved into atmospheric studies and satellite observations, setting the stage for CO2 measurements from space.
Establishing Ground-Based Stations
In the early 2000s, observing networks began cropping up globally to solidify ground-based carbon measurement capabilities. One such network is the Total Carbon Column Observing Network (TCCON), founded in 2004. It expanded over years to include around 30 stations globally, contributing significantly to validating satellite data.
The Integrated Carbon Observation System (ICOS) is another praiseworthy initiative in this regard. With over 130 stations across Europe as of 2020, ICOS aims at providing long-term observations required to understand earthly carbon cycles efficiently.
The Global Greenhouse Gas Reference Network managed by NOAA’s Earth System Research Laboratories entered the scene around this time. This network includes over 50 sites taking precise measurements illustrating an ongoing increase in global atmospheric carbon concentrations.
The newfound interest and advancements in setting up extensive ground-based networks marked a distinct milestone in our journey understanding global carbon movements.

In recent years, space-based carbon observing systems have emerged as essential tools to map CO2 concentrations on a global scale. NASA launched the Orbiting Carbon Observatory-2 (OCO-2) in July 2014, which gathers nearly 400,000 precise atmospheric CO2 measurements daily across the globe.
More recently, Carbon Mapper, a nonprofit organization including several partnerships aims to launch its own fleet of hyperspectral satellites by 2023. This exciting development illustrates how far we’ve advanced in carbon observation technology since the days of Keeling and Mauna Loa.
All these milestones reflect decades-long concerted efforts and show our dedication towards understanding and preserving our planetary life-support system. As we continue improving our tools and comprehension of these processes, one can only hope for more exciting breakthroughs in carbon observing systems in the future.
Advent of Satellite Carbon Observations
As concerns regarding climate change became rampant during the latter half of the 20th century, the need to track global carbon movements became increasingly urgent. This led scientists to look beyond earth-bound methods and devise advanced means for tracking atmospheric carbon dioxide levels. The solution was found outside our planet’s boundaries: satellite-based carbon observing systems.
The ability of satellites to monitor and gather data across vast and remote areas of the earth has proven to be a game-changer for carbon observation. These advanced technologies can provide comprehensive data on global atmospheric CO2 levels, making it feasible to track entire regions simultaneously rather than piecing together an extensive patchwork of ground-based measurements.
These innovations in space technology provided researchers with invaluable tools to deepen their understanding of climate change dynamics. Your journey exploring remote sensing, geographic information systems, and the world of satellites starts right here.
