PACE’s Ocean Color Instrument (OCI) detects light across a hyperspectral range from the ultraviolet to near-infrared, which gives scientists new information to differentiate communities of phytoplankton – a unique ability of NASA’s newest Earth-observing satellite. This first image released from OCI identifies two different communities of these microscopic marine organisms in the ocean off South Africa on Feb. 28, 2024. The central panel of this image shows <em>Synechococcus</em> in pink and picoeukaryotes in green. The left panel of this image shows a natural color view of the ocean, and the right panel displays the concentration of chlorophyll-a, a photosynthetic pigment used to identify the presence of phytoplankton.

PACE’s OCI instrument collects data that can be used to study atmospheric conditions. The top three panels of this OCI image depicting dust from Northern Africa carried into the Mediterranean Sea, show data that scientists have been able to collect in the past using satellite instruments – true color images, aerosol optical depth, and the UV aerosol index. The bottom two images visualize novel pieces of data that will help scientists create more accurate climate models. Single-Scattering Albedo (SSA) tells the fraction of light scattered or absorbed, which will be used to improve climate models. Aerosol Layer Height tells how low to the ground or high in the atmosphere aerosols are, which aids in understanding air quality. Credit: NASA/UMBC

Early data from the SPEXone polarimeter instrument aboard PACE show aerosols in a diagonal swath over Japan on Mar. 16, 2024, and Ethiopia on Mar. 6, 2024. In the top two panels, lighter colors represent a higher fraction of polarized light. In the bottom panels, SPEXone data has been used to differentiate between fine aerosols, like smoke, and coarse aerosols, like dust and sea spray. SPEXone data can also measure how much aerosols are absorbing light from the Sun. Above Ethiopia, the data show mostly fine particles absorbing sunlight, which is typical for smoke from biomass burning. In Japan, there are also fine aerosols, but without the same absorption. This indicates urban pollution from Tokyo, blown toward the ocean and mixed with sea salt. The SPEXone polarization observations are displayed on a background true color image from another of PACE’s instruments, OCI. Credit: SRON

Early images from PACE’s HARP2 polarimeter captured data on clouds over the west coast of South America on Mar. 11, 2024. The polarimetry data can be used to determine information about the cloud droplets that make up the cloudbow – a rainbow produced by sunlight reflected by cloud droplets instead of rain droplets. Scientists can learn how the clouds respond to man-made pollution and other aerosols and can measure the size of the cloud droplets with this polarimetry data. Credit: UMBC
