Science and Applications Team 3

The goal of the PACE Science and Applications Team (SAT) is product development that further enables basic and applied research using PACE data. SAT members are developing data products, applications, and models to help address existing informational gaps or science questions across disciplines and at different Earth System interfaces using PACE data.

The SAT is retrieving new and/or improved data products from the satellite’s instruments (OCI, HARP2, and SPEXone). This includes development of novel geophysical variables and integration of PACE data records into Earth System models.

About Us
The selected Science and Applications Team (SAT) is a diverse group of investigators who cumulatively bring end-to-end knowledge of different aspects of the breadth of basic and applied research and applications possible from the PACE observatory, as well as the scientific, algorithm, and modeling approaches of measurements and data products needed to address the science questions of the mission.
Science Meetings
The final PACE Science and Applications Team Meeting prior to launch was held in February 2023. It included 23 science mini-talks, programmatic and instrument team presentations, team and mission updates, and a review of uncertainties and flagging, filling UV data gaps, and plans for calibrating / validating PACE data. MORE
The second meeting of the PACE Science and Applications Team was held in October 2021. The meeting included 25 science mini-talks, programmatic and instrument team presentations, team and mission updates, and a review of uncertainties, gaps, data needs, and data validation. MORE
The first meeting of the PACE Science and Applications Team (SAT) was held online in June 2020. The meeting opened with several presentations about the PACE Project, including details about the Ocean Color Instrument and polarimeters. Each SAT member gave a brief overview of his or her research and then fielded questions from the audience. MORE
The fourth meeting of the PACE Science Team was held at the Harbor Branch Oceanographic Institute in January of 2018. The meeting consisted of a virtual, self-paced segment in which science team members prepared and viewed narrated versions of their presentations in preparation for the meeting, followed by an in-person meeting. The first day focused on the PACE Science Team deliverables and plans for the polarimeters. The second day focused on engineering challenge of PACE as well as the results from Cal/Val concepts. On the final day, subgroups reported on their activities. For many of the presentations, both a narrated video and a PDF of the talk is available. MORE
The third meeting of the PACE Science Team (ST) was held during mid-January 2017 at the Harbor Branch Oceanographic Institute in Florida, USA. The meeting consisted of a virtual, self-paced segment in which science team members prepared and viewed narrated versions of their presentations in preparation for the meeting, followed by an in-person meeting. Science Team members formed break-out groups to discuss the status of major project areas, including the retrieval of inherent optical properties (IOP) and atmospheric corrections (AC). Field campaign results and potential applications for PACE measurements were reviewed. MORE
The second meeting of the PACE Science Team (ST) was held during mid-January 2016 in Pasadena, CA. Threshold Requirements for the PACE Mission, minimum capabilities for the polarimeter, and instrument trade study results were shared. An overview of the mission and top-level schedule were presented along with science implementation priorities. ST presentations fell in to the general categories of applications, science impacts related to the designs of the Ocean Color Instrument and other sensors, retrieval of inherent optical properties and atmospheric correction. The meeting concluded with reports from ST subgroups and plans for future PACE ST documents. MORE
The first face-to-face meeting of the PACE Science Team (ST) was held during mid-January 2015 in College Park, MD. The opening discussion covered approaches for defining the project elements (i.e., science, data processing and analysis, post-launch calibration/validation; procurement of spacecraft and polarimeter) within the mission cost cap. After reviewing recommendations of the PACE Science Definition Team, ST presentations fell under the general themes of atmospheric correction, inherent optical properties, and applied sciences. The meeting concluded by setting ST goals and a work plan for the subsequent year. MORE
In mid-March 2012, the PACE Science Definition Team (SDT) held its second community workshop in Arlington, VA. In addition to reviewing outcomes from the previous meeting (Nov 2011), the outline and schedule for the SDT report was addressed. Information exchanges between the SDT and PACE Engineering Team were a key focus of the meeting. In addition, disciplinary groups (oceans, atmosphere) discussed relevant sections of the SDT report, including reviews of completeness and science traceability. The workshop concluded with formalizing and assigning action items needed for the final SDT report (which was completed in October 2012). MORE
In 2011, NASA selected the PACE science definition team (SDT) via an open solicitation. Composed of ocean, aerosol, and cloud scientists, the SDT held its first open community workshop in Arlington, VA. The team was tasked with providing science input to the NASA's PACE mission study (ocean biology/ecology/chemistry and clouds/aerosols) and CNES's polarimeter instrument study. The SDT was charged with defining the science content of the mission and working closely with the engineering team to define (a) mission concept(s) that optimizes science, cost, and risk. They are also responsible for defining and defending the science value of the mission concept(s). MORE
Other Key Meetings
Co-sponsored by the American Geophysical Union (AGU), the Association for the Sciences of Limnology and Oceanography (ASLO), and The Oceanography Society (TOS), Ocean Sciences Meeting (OSM) is the global leader in ocean sciences conferences. Balance is key to OSM 22 – enabling as many people to meet as possible across media, disseminating scientific knowledge, and creating personal connections all while considering the ocean and planet we want for the future.

The NASA PACE project, in collaboration with the International Ocean-Colour Coordinating Group (IOCCG), have initiated a new working group to establish standard, community-consensus field protocols for measuring aquatic primary productivity in coastal and ocean waters across diverse methodologies. Approximately two dozen active investigators with experience in conducting field, laboratory, and remote sensing measurements of aquatic primary productivity will work jointly in the development of a set of community consensus protocols for carrying out in situ measurements of primary productivity and related parameters. The objective is to generate recommendations for best practices to homogenize methodologies, and to account for known artifacts and sources of error across the various measurement approaches. MORE
The Ocean Color Research Team (OCRT) meeting was held on May 2-4 in Silver Spring, MD. The meeting featured both oral presentations and posters, which included content on currently-operating missions, upcoming solicitations, the PACE mission, and the upcoming Decadal Survey. MORE
The session,"Frontiers in Ocean Color Remote Sensing: Science and Challenges," was held during the Ocean Sciences Meeting (26-Feb-16). Advanced technologies and frequent, repeated, multi-scale satellite observations, in combination with field measurements, are essential for observing and predicting changes in Earth's ocean. Presentations explored the next generation of ocean science questions from ocean-observing satellites and challenges to those observations from science, technology, and modeling perspectives. MORE
