STAR Seminars

Welcome to the STAR science seminar listings page. The STAR seminar series listings include STAR seminars, NOCCG seminars starting in 2019, and CoastWatch seminars, newly added for 2022.

NOAA's Ocean Color Coordinating Group (NOCCG) is a NOAA organization founded in 2011 by Dr. Paul DiGiacomo, Chief of SOCD at NOAA/NESDIS/STAR and was formally recognized by NESDIS in response to the National Research Council’s 2011 report, “Assessing the Requirements for Sustained Ocean Color Research and Operations.” The purpose of the NOCCG is to keep members up to date about developments for satellite ocean color. With membership that includes representatives from all the NOAA line offices, NOCCG holds monthly meetings and an informational seminar, advertised widely both within and outside of NOAA, especially to the US ocean color community.

The NOAA CoastWatch Seminars, begun in January 2022, feature two speakers per month from the NOAA CoastWatch Science or Application Team presenting information that will be of interest to NOAA CoastWatch Users and the entire CoastWatch Team.

Abstract: Satellite constellations such as Sentinel-2A and -2B, Sentinel-3A and -3B, and Planet's PlanetScope constellation offer increased temporal resolution while maintaining spatial, spectral, and radiometric resolutions. For most satellite constellations currently in orbit, platforms are launched either in a group or individually, typically across several years. This increases sampling frequency throughout the satellite mission's lifespan and presents the opportunity to observe more extreme events. When assessing long-term trends or year-over-year change, increased sampling frequency can lead to observed changes that are incorrectly attributed to changes in environmental conditions. This study uses water quality data from the Copernicus Sentinel-3 satellite series to assess temporal aggregation methods for multi-platform satellite missions and their impact on resulting data distributions and change assessments. Temporal aggregation via the maximum data value and via the median data value were compared via the Wilcoxon signed-rank test for a simulation study and for water quality data produced by the Cyanobacteria Assessment Network (CyAN). Next, trends in water quality data were assessed for each temporal aggregation approach using the seasonal Mann-Kendall test for trend and associated Thiel-Sen slope. Results can inform large-scale, long-term water quality monitoring efforts and applications that combine multiple satellite missions, including sensor agnostic workflows.

Title: NOAA CoastWatch: UN Ocean Decade - Observing Air-Sea Interactions Strategy
Presenter(s): Meghan Cronin, OAR
Date & Time: 23 May 2024
4:00 pm - 5:00 pm ET
Location: Webinar
Description:

NOAA Science Seminar Series

Title: A UN Ocean Decade Program, co-led by NOAA, Linking Air-Sea Interaction In Situ Observations, Satellites and Earth System Models for A Predicted, Safe, Healthy, Clean, and Productive Ocean


Presenter(s): Meghan Cronin (OAR)

Abstract: A look at NOAA activities related to the UN Ocean Decade program "Observing Air-Sea Interactions Strategy". Covering Ocean Climate Stations, OceanSITES longterm ocean surface mooring timeseries that can be used for assessing satellites, and also a new Tropical Pacific Observing System (TPOS) Equatorial Pacific Experiment (TEPEX) on the horizon. Discussion will cover how these observations might be used to help improve satellites and quantify uncertainties, how these are then linked to improved models and ultimately to the UN Decade goals of a Predicted Ocean, Safe Ocean, etc.
