Arctic Bottom Pressure Recorder: Hourly Ocean Pressure at the North Pole

Hourly ocean bottom pressure measurements from the first year of a 5-year deployment at the North Pole, initiated in August 2022. The dataset, provided by NASA, reports pressure as liquid water equivalent thickness and temperature in a single netCDF file. It is designed to serve as in situ validation for GRACE-FO satellite data products in the central Arctic.

Use Cases

• Validate GRACE-FO satellite ocean bottom pressure data products based on in-situ measurements.
• Analyze temporal variability in Arctic Ocean bottom pressure based on hourly time-series data.
• Study the relationship between ocean bottom pressure and temperature in the central Arctic.
• Assess long-term oceanographic trends in the Arctic using a planned 5-year record.

Strengths

• First year of a planned 5-year continuous record, indicating a long-term observational commitment.
• Data is quality-controlled and updated yearly at the PO.DAAC repository.
• Reports two key variables: bottom pressure and temperature.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
