The PO.DAAC is pleased to announce the public release of the GHRSST Level 4 SPoRT Global Foundation Sea Surface Temperature Analysis (v1.0) dataset produced by the NASA Short-term Prediction Research and Transition (SPoRT) project at the NASA Marshall Space Flight Center (MSFC). This dataset provides continuous, high-resolution, composited near-global (80N-80S) sea surface temperature fields twice daily at 2 km resolution for regional weather, maritime, and coastal applications.
The SPoRT SST analysis composites seven-days of Visible Infrared Imaging Radiometer Suite (VIIRS) and Advanced Very High Resolution Radiometer (AVHRR) satellite L2 SST data, with additional data from OSTIA and Geo-Polar Blended L4 SST products into a single analysis. Two types of weighting are used in the compositing process. One weight is for the data latency and the other for the product type. The VIIRS and AVHRR data, being at 750m and 1km resolution respectively, are given the most weight, while the L4 datasets are given weaker weights. The data are packaged according to the GHRSST Data Specification version 2 (GDS2) in netCDF4 format. More information regarding GHRSST is available from PO.DAAC’s GHRSST mission page.
The MSFC SPoRT SST Level 4 Version 1.0 dataset is described and discoverable via the PO.DAAC data portal.
