Short Name:

GHRSST NOAA/STAR ACSPO v2.80 0.02 degree L3S Dataset from Afternoon LEO Satellites (GDS v2)

NOAA STAR produces two product lines of gridded 0.02 degree super-collated L3S LEO sub-skin Sea Surface Temperature (SST) datasets, one from the NOAA afternoon JPSS (L3S_LEO_PM) satellites and the other from the EUMETSAT mid-morning Metop (L3S_LEO_AM) satellites. The L3S_LEO_PM is derived from JPSS satellites (currently, NPP and N20) with VIIRS sensor onboard, replacing the NOAA POES system with AVHRR GAC (4km/nadir). The L3S_LEO_PM dataset is produced by aggregating L3U datasets from JPSS satellites ( and ) and covers from Feb 2012-present. The L3S_LEO_PM SST dataset is reported in two files per 24-hour interval, daytime and nighttime, approximately at the nominal JPSS local equator crossing times around 01:30/13:30. Data is in NetCDF4 format, compliant with the GHRSST Data Specification version 2 (GDS2). The Near Real Time (NRT) L3S-LEO data are archived at PODAAC with approximately 6 hours latency, and then replaced by the Re-ANalysis (RAN) files about 2 months later, with identical file names. The dataset is validated against quality controlled in situ data, provided by the NOAA in situ SST Quality Monitor system (iQuam; Xu and Ignatov, 2014), and monitored in another NOAA system, SST Quality Monitor (SQUAM; Dash et al, 2010). The L3S SST imagery and local coverage are continuously evaluated, and checked for consistency with other Level 2, 3 and 4 datasets in the ACSPO Regional Monitor for SST (ARMS) system. NOAA plans to include data from other afternoon platforms and sensors, such as N21 and Aqua MODIS, into L3S_LEO_PM. More information about the dataset can be found under the Documentation and Citation tabs.
