Global Ocean Front Probability, Uncertainty, and Front Line Dataset (2001-2024)

Global Ocean Front Probability, Uncertainty, and Front Line Dataset provides daily global ocean front probability fields, uncertainty estimates, and vectorized front-line products derived from NOAA Coral Reef Watch (CRW) Version 3.1 daily 5-km Sea Surface Temperature (SST) observations during 2001--2024.The dataset is organized into three complementary data products:1.NetCDF ProductsDaily global front probability and uncertainty fields are provided in annual NetCDF files:netcdf_files/ ├── global_front_probability_uncertainty_2001.nc ├── global_front_probability_uncertainty_2002.nc ├── ... └── global_front_probability_uncertainty_2024.nc Each file contains:1) Ensemble: front occurrence probability (0--1)2) Uncertainty: inter-algorithm standard deviation (0--1)3) Latitude and Longitude coordinates4) Daily temporal dimension2.GeoTIFF ProductsMonthly climatological composites are provided as GeoTIFF files:geotiff_files/ ├── 200101_monthly_probability.tif ├── 200101_monthly_uncertainty.tif ├── ... └── 202412_monthly_uncertainty.tif These files facilitate visualization and GIS-based analysis.3.GeoJSON Front-Line ProductsVectorized ocean fronts are distributed as GeoJSON files organized by ocean partition and date:geojson_files/ ├── 01/ │ ├── 20010101.geojson │ ├── 20010102.geojson │ └── ... ├── 02/ │ └── ... ├── ... └── 44/ Each GeoJSON file contains multiple front-line features represented by geographic coordinates.

Every front includes:1) id: unique front identifier2) probability: mean front probability along the front axis3) length (km): front length in kilometersThese vector products enable direct frontal tracking, statistical analysis, and integration with geographic information systems.The dataset covers the global ocean between 60°S and 60°N at a spatial resolution of approximately 5 km (0.05°) and spans 24 years of continuous daily observations.
