The Ocean Color Forum (including our subforum for Field Data - SeaBASS) has transitioned to the burgeoning Earthdata Forum (https://forum.earthdata.nasa.gov/). We encourage you to ask questions there and we look forward to interacting with you.
The new forum is organized using tags. Pick the "SeaBASS" tag to search for existing SeaBASS posts, or when you create a new post. There are a variety of search options; if you use the "Search By Tags" feature then SeaBASS is under the dropdown "Major Project". Other relevant tags include "Ocean" for Discipline and "OB DAAC" as the DAAC.
You can bookmark your favorite searches using your browser if you want a shortcut. Also, later this year a feature will be added allowing you to follow specific tags and receive email notifications whenever there is a new post.
The SeaBASS website has received a new look to go along with several background updates and small accessibility changes.
The filename extension ".sb" is now officially used to identify the SeaBASS file format. Read more. Data submitters, please use ".sb" when creating future file names (instead of .csv, .txt, etc.) Data users should note that a large percentage of historical files have had their names updated to the new standard. Other than the metadata "/data_file_name" being updated, the contents and format are otherwise unchanged.
A new Data Submission Special Requirements page has been launched. It has requirements and examples for various types of data. When preparing a new submission, check to see if your data type is listed on that page. If so, review the conditionally required metadata, and optionally read tips or examples for formatting your files.
Importantly, some submissions must now include a checklist document listed under required extra documents. Checklists forms were designed to standardize and better preserve critical methods and analysis details that are part of community vetted protocols.
SeaBASS SST Validation results are being reprocessed to R2019.0 (Aqua- & Terra-MODIS) and R2016.2 (SNPP-VIIRS). Over the coming weeks the results files will be in flux, and might be updated multiple times. The old match-ups are available here.
Results are now available from a new sea surface temperature (SST) validation system providing ground-truth of satellite-borne measurements via comparisons with coincident in situ temperature measurements. Successful match-ups are compiled into one global file per date for each different sensor, and made available via a simple web-based search engine and API. More info. Produced in collaboration with the SST group at the Rosenstiel School of Marine and Atmospheric Science at the University of Miami.
Recently released AERONET-OC data (Version 2, level 2.0) were processed for SeaBASS validation. These data were also used to create SeaBASS's first VIIRS-JPSS1 validation results.
Several new metadata headers have been created to make it easier to interpret useful information without users needing to manually parse external documents. These new headers are optional but recommended from now on:
New field names are added SeaBASS over time to meet the needs of evolving science and new types of submissions. New fields are not usually announced, but special attention is called to the recently added variations of commonly submitted measurements. These variants were added to keep distinct measurements or derivations whose methodology imparts significant differences or caveats compared to other techniques. Effort is made to avoid creating an unnecessary amount of field names in SeaBASS, but that is balanced by also trying to prevent lumping together distinct measurements in a way that cannot be separated easily.
A new web-based SeaBASS Regional Time Series Tool is available under "Get Data" in the main menu. It is designed to visualize and serve time-based comparisons of satellite-to-satellite and in situ measurements.
For a given region, one or more satellite sensors must be selected and then all available satellite and in situ data validation data within the bounds of the study site will be combined for comparison as figures and percent frequency distributions. User options are available to select a measurement product of interest (e.g., Rrs, IOPs, Chl, etc), adjust the data averaging period (weekly, monthly, seasonal), the date range, and other graphing options. Each region has a brief description that includes links to extra information about the primary in situ data sources and a map that shows the boundaries used to define each region. With the click of a button, users may also download the source data.
