It took a network of scientists at NASA and research institutions around the world more than 20 years to carefully craft and test the novel instruments that allow PACE to study the ocean and atmosphere with unprecedented clarity.<\/p>\n\n\n\n<p>In the early 2000s, a team of scientists at <a href=\"https:\/\/www.nasa.gov\/goddard\">NASA\u2019s Goddard Space Flight Center<\/a> in Greenbelt, Maryland, prototyped the <a href=\"https:\/\/www.nasa.gov\/technology\/orca-prototype-ready-for-the-open-ocean\/\">Ocean Radiometer for Carbon Assessment (ORCA)<\/a> instrument, which ultimately became PACE\u2019s primary research tool: the <a href=\"https:\/\/pace.oceansciences.org\/oci.htm\" rel=\"noopener\">Ocean Color instrument (OCI).<\/a> Then, in the 2010s, a team from the University of Maryland, Baltimore County (UMBC), worked with NASA to prototype the <a href=\"https:\/\/science.nasa.gov\/science-research\/science-enabling-technology\/technology-highlights\/new-cubesats-first-light-shows-clouds-and-aerosols\/\" rel=\"noopener\">Hyper Angular Rainbow Polarimeter (HARP),<\/a> a shoebox-sized instrument that will collect groundbreaking measurements of atmospheric aerosols.<\/p>\n\n\n\n<p>Neither PACE’s OCI nor <a href=\"https:\/\/pace.oceansciences.org\/harp2.htm\" rel=\"noopener\">HARP2<\/a> \u2014 a nearly exact copy of the HARP prototype \u2014 would exist were it not for NASA\u2019s early investments in novel technologies for Earth observation through competitive grants distributed by the agency\u2019s <a href=\"http:\/\/esto.nasa.gov\/\" rel=\"noopener\">Earth Science Technology Office (ESTO).<\/a> Over the last 25 years, ESTO has managed the development of more than 1,100 new technologies for gathering science measurements.<\/p>\n\n\n\n<p>\u201cAll of this investment in the tech development early on basically made it much, much easier for us to build the observatory into what it is today,\u201d said Jeremy Werdell, an oceanographer at NASA Goddard and project scientist for PACE.<\/p>\n\n\n\n<p>Charles \u201cChuck\u201d McClain, who led the ORCA research team until his retirement in 2013, said NASA\u2019s commitment to technology development is a cornerstone of PACE\u2019s success. \u201cWithout ESTO, it wouldn\u2019t have happened. It was a long and winding road, getting to where we are today.\u201d<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp\"><img fetchpriority=\"high\" decoding=\"async\" width=\"2048\" height=\"1583\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?w=2048\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"three men standing beside a small, black piece of space satellite hardware\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp 3300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=300,232 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=768,593 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=1024,791 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=1536,1187 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=2048,1583 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=400,309 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=600,464 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=900,695 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=1200,927 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/orca-team.webp?resize=2000,1545 2000w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" loading=\"eager\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Left to right: Gerhard Meister, Bryan Monosmith, and Chuck McClain are shown here at NASA’s Goddard Space Flight Center in Greenbelt, Md., in 2015 with the Ocean Radiometer for Carbon Assessment (ORCA) prototype that led to the Ocean Color Instrument (OCI) aboard NASA\u2019s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission.<\/div><div class=\"hds-credits\">NASA\/Bill Hrybyk<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>It was ORCA that first demonstrated a telescope rotating at a speed of six revolutions per second could synchronize perfectly with an array of charge-coupled devices \u2014 microchips that transform telescopic projections into digital images. This innovation made it possible for OCI to observe hyperspectral shades of ocean color previously unobtainable using space-based sensors.<\/p>\n\n\n\n<p>But what made ORCA especially appealing to PACE was its pedigree of thorough testing. \u201cOne really important consideration was technology readiness,” said Gerhard Meister, who took over ORCA after McClain retired and serves as OCI instrument scientist. Compared to other ocean radiometer designs that were considered for PACE, “we had this instrument that was ready, and we had shown that it would work.\u201d<\/p>\n\n\n\n<p>Technology readiness also made HARP an appealing solution to PACE\u2019s <a href=\"https:\/\/svs.gsfc.nasa.gov\/14454\" rel=\"noopener\">polarimeter<\/a> challenge. Mission engineers needed an instrument powerful enough to ensure PACE\u2019s ocean color measurements weren\u2019t jeopardized by atmospheric interference, but compact enough to fly on the PACE observatory platform.<\/p>\n\n\n\n<p>By the time Vanderlei Martins, an atmospheric scientist at UMBC, first spoke to Werdell about incorporating a version of HARP into PACE in 2016, he had proven the technology with <a href=\"https:\/\/impact.earthdata.nasa.gov\/casei\/instrument\/AirHARP\" rel=\"noopener\">AirHARP,<\/a> an airplane-mounted version of HARP, and was using an ESTO award to prepare <a href=\"https:\/\/esto.nasa.gov\/25years\/harp\/\" rel=\"noopener\">HARP CubeSat<\/a> for space.<\/p>\n\n\n\n<p>HARP2 relies on the same optical system developed through AirHARP and HARP CubeSat. A wide-angle lens observes Earth\u2019s surface from up to 60 different viewing angles with a spatial resolution of 1.62 miles (2.6kilometers) per pixel, all without any moving parts. This gives researchers a global view of aerosols from a tiny instrument that consumes very little energy.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div

continues making a difference to researchers like <a href=\"https:\/\/pace.oceansciences.org\/people_ea.htm?id=107\" rel=\"noopener\">Jessie Turner,<\/a> an oceanographer at the University of Connecticut who will use PACE to study algal blooms and water clarity in the Chesapeake Bay.<\/p>\n\n\n\n<p>\u201cFor my application that I\u2019m building for early adopters of PACE data, I actually think that polarimeters are going to be really useful because that\u2019s something we haven\u2019t fully done before for the ocean,\u201d Turner said. \u201cPolarimetric data can actually help us see what kind of particles are in the water.\u201d<\/p>\n\n\n\n<p>Without the early development and test-drives of the instruments from McClain\u2019s and Martins\u2019 teams, PACE as we know it wouldn\u2019t exist.<\/p>\n\n\n\n<p>\u201cIt all kind of fell in place in a timely manner that allowed us to mature the instruments, along with the science, just in time for PACE,\u201d said
