This state-of-the-art satellite, launched in February 2024 and currently orbiting Earth at an altitude of about 250 miles, promises to revolutionize our ability to monitor the health of our oceans and atmosphere. By collecting critical data on how these vital systems are responding to a warming world, PACE will empower scientists to develop more accurate climate models and design more effective strategies for mitigating the effects of climate change.
One of PACE’s primary areas of focus is the health of our oceans. Phytoplankton, microscopic marine plants that play an outsized role in absorbing carbon dioxide from the atmosphere, will be under close scrutiny by PACE’s advanced instruments. By tracking changes in phytoplankton populations, scientists will be able to better understand how climate change is impacting the ocean’s ability to store carbon, a crucial factor in regulating global temperatures.
PACE’s capabilities extend far beyond studying phytoplankton. The satellite is also equipped to collect data on aerosols, tiny particles suspended in the atmosphere that can significantly impact air quality and climate. By monitoring these aerosols, scientists can gain valuable insights into how human activities and natural processes are affecting air quality on a global scale.
Clouds play a complex and critical role in regulating Earth’s climate. PACE’s sophisticated sensors will be able to measure cloud properties in unprecedented detail, providing scientists with a clearer picture of how clouds are changing in response to climate change. This information is essential for developing more accurate climate models that can better predict future climate trends.
The data collected by PACE will be freely available to researchers around the globe, fostering international collaboration in the fight against climate change. This open access to data will empower scientists to develop more sophisticated climate models, design more effective strategies for mitigating the effects of climate change, and ultimately, protect our planet for generations to come.
The launch of PACE marks a significant step forward in our understanding of Earth’s climate system. By providing comprehensive data on the health of our oceans, atmosphere, and cloud cover, PACE will equip scientists with the tools they need to develop solutions for a more sustainable future.
