The data on Ocean, Atmosphere, Climate is now available from NASA

Precise News

NASA is now publicly distributing science-quality data from its newest Earth-observing satellite, providing first-of-their-kind measurements of ocean health, air quality, and the effects of a changing climate.
The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite was launched on Feb. 8, and has been put through several weeks of in-orbit testing of the spacecraft and instruments to ensure proper functioning and data quality.
The mission is gathering data that the public now can access at
PACE data will allow researchers to study microscopic life in the ocean and particles in the air, advancing the understanding of issues including fisheries health, harmful algal blooms, air pollution, and wildfire smoke.
With PACE, scientists also can investigate how the ocean and atmosphere interact with each other and are affected by a changing climate.
From coastal communities to fisheries, NASA is gathering critical climate data for all people.” “First light from the PACE mission is a major milestone in our ongoing efforts to better understand our changing planet.
The satellite’s Ocean Color Instrument, which was built and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, observes the ocean, land, and atmosphere across a spectrum of ultraviolet, visible, and near infrared light.
While previous ocean color satellites could only detect a handful of wavelengths, PACE is detecting more than 200 wavelengths.


NASA is now making science-quality data from its newest Earth-observing satellite available to the public. These data include unprecedented measurements of ocean health, air quality, and the consequences of climate change.

On February, the Plankton, Aerosol, Cloud, and Ocean Ecosystem (PACE) satellite was launched. 8. To guarantee appropriate operation and high-quality data, the spacecraft and instruments have undergone several weeks of in-orbit testing. The goal is to collect data that is currently available for public access at https://pace. OceanSciences.Org/Access_Pace_Data.htm.

In order to better understand problems like harmful algal blooms, air pollution, wildfire smoke, and fisheries health, researchers will be able to examine microscopic life in the ocean and airborne particles thanks to PACE data. With PACE, researchers can also look into the interactions and effects of a changing climate on the ocean and atmosphere.

NASA Administrator Bill Nelson stated, “These breathtaking photos are enhancing NASA’s dedication to safeguarding our home planet.”. “Our knowledge of the effects of our oceans, waterways, and the microscopic life that resides there will improve thanks to PACE’s observations. NASA is gathering vital climate data that affects everyone, from fisheries to coastal communities. “.

“The PACE mission’s first light marks a significant advancement in our continuing quest to comprehend our planet’s changing environment. The moon’s surface is better understood than that of our own oceans, despite the fact that Earth is a water planet. One of the major projects that are ushering in a new era of Earth science is PACE, along with SWOT and the forthcoming NISAR mission, according to Karen St. The director of NASA’s Earth Science Division is Germain.

Through the use of ultraviolet, visible, and near infrared light, NASA’s Goddard Space Flight Center in Greenbelt, Maryland, designed and oversaw the construction of the Ocean Color Instrument on board the satellite, which records images of the ocean, land, and atmosphere. PACE is detecting more than 200 wavelengths, whereas earlier ocean color satellites could only identify a small number of wavelengths. Scientists are able to distinguish distinct phytoplankton communities thanks to this wide spectral range. Differentiating between phytoplankton communities is a crucial task of the satellite because different species have different roles in the ecosystem and carbon cycle. The majority of these species are benign, but some can be harmful to human health.

Polarized light that has been reflected off of clouds and microscopic particles in the atmosphere is measured by PACE’s two multi-angle polarimeters, SPEXone and HARP2. These particles, also referred to as aerosols, can include smoke, dust, sea spray, and other substances. In terms of their capabilities, the two polarimeters are complementary. Built at Airbus Netherlands B and the Netherlands Institute for Space Research (SRON), SPEXone. VIII. intends to observe Earth from five distinct viewing angles in hyperspectral resolution, which will allow it to detect every color in the rainbow. Constructed at the University of Maryland, Baltimore County (UMBC), HARP2 is designed to observe four distinct light wavelengths from 60 distinct viewing angles.

These data will help scientists monitor, identify, and analyze atmospheric aerosols to better inform the public about air quality, as well as measure cloud properties, which are crucial for understanding climate. In order to build precise climate models, scientists will also be able to understand how aerosols interact with clouds and affect their formation.

For more than 20 years, PACE-like imagery has been appearing in our dreams. Jeremy Werdell, a NASA Goddard PACE project scientist, remarked, “It’s bizarre to finally see the real thing.”. “I’m proud of our team for achieving that, as the data from all three instruments are of such high quality that we can start making it publicly available two months from launch.”. Insights regarding aquatic ecosystem health and air quality from this data will not only improve our daily lives but will gradually alter our perception of our home planet. “.

NASA Goddard is in charge of overseeing the PACE mission and is also responsible for building and testing the spacecraft and ocean color instrument. A consortium led by the Netherlands Institute for Space Research, Airbus Defence, and Space Netherlands developed and constructed the Spectro-polarimeter for Planetary Exploration (SPEXone), while the University of Maryland, Baltimore County designed and constructed the Hyper-Angular Rainbow Polarimeter 2 (HARP2).
