GOES-17 Satellite Sea Surface Temperature Grids For The Americas

13 hourly data granules are produced per day, covering a 12-hour observation window from 20UTC to 08UTC. This Level 3 Collated dataset provides gridded sea surface temperature measurements from the NOAA/STAR GOES-17 ABI sensor, processed by the GHRSSTCWIC organization and formatted per GHRSST Data Specification version 2.

Use Cases

• Analyzing diurnal SST variation patterns using the 1hr temporal resolution and the day/night flag within the l2p_flags layer.
• Assessing satellite SST retrieval accuracy by comparing the 'ACSPO SST minus reference' layer against the Canadian Met Centre L4 SST analysis.
• Masking out non-ocean areas for analysis using the land and ice flags provided in the l2p_flags layer.
• Estimating uncertainty in SST values for each pixel using the Sensor-Specific Error Statistics layers for bias and standard deviation.
• Filtering for clear-sky ocean observations using the ACSPO clear-sky mask (ACSM) to reduce cloud contamination in time-series studies.

Strengths

• Data volume is 0.1GB per day, facilitating manageable storage and transfer.
• Includes pixel-level error statistics (bias and standard deviation) for uncertainty quantification.
• Monitored and validated against iQuam in situ data via the SQUAM system.

Limitations

• Limited temporal coverage with a 12-hour daily observation window and a 10-hour data gap.
• SST data over internal waters like lakes and rivers may lack sufficient in situ validation.
• Dataset is affected by the known loop heat pipe (LHP) issue on the GOES-17 ABI sensor.
