NASA announces SeaDAS 11 Release – free satellite data processing software

SeaDAS is FREE, open-source software built by NASA’s Ocean Ecology Lab to directly support easy processing, visualization, and analysis of all PACE data products and data levels (Level 1 – Level 4) as well as other satellite data products provided by the NASA OB.DAAC.

The NASA SeaDAS team are pleased to announce the release of SeaDAS 11.0.0!

Highlights of what’s new:

Improved Data Handling – Correct support for L3m datasets that cross the dateline, improved handling of HARP2 and SPEXONE Level-2 products with 4D bands, and fixes for CZCS L2 image orientation.
Map Gridlines Enhancements – Improved rendering for global datasets and dateline-crossing scenes, with better labeling and performance for large-area visualizations.
Earthdata Cloud Spatial Subsetting – New OB_CLOUD Spatial Subset Tool retrieves Level-2 subsets from Earthdata Cloud via Harmony L2SS. Supports selection of individual 2D variables (e.g., chlor_a). When using variable subsetting, quality flags (e.g., l2_flags) are not included, and multi-dimensional variables (e.g., Rrs) are not supported. Spatial subsetting preserves full data and should be used for quality-controlled analysis.
Enhanced OB_CLOUD Data Browser – Added “Regions” selector for bounded geographic subsetting and improved integration with the Spatial Subset Tool.
GPT Cross-Platform Support – Graph Processing Tool (GPT) now fully functional on Windows, macOS, and Linux.
Platform and Installer Updates – Integrated with SNAP 13 and Java 21. Installers available with and without bundled JRE for Windows, Linux, and Apple Silicon macOS. Intel-based Mac support has been discontinued.
