Optimally interpolated atmospheric surface pressure data for the Arctic Ocean Basin, provided at 12-hour intervals. The dataset originates from SCIOPS and was last updated in November 2007. It offers a spatial grid with a 2-degree latitude by 10-degree longitude resolution.
Use Cases
- Analyze temporal pressure trends at 0Z and 12Z intervals across the Arctic Basin.
- Map spatial pressure gradients using the 2-degree latitude by 10-degree longitude grid.
- Validate or calibrate climate model outputs for the region between 70°N and 90°N latitude.
Strengths
- Data is optimally interpolated to provide a continuous spatial field.
- Twice-daily temporal resolution (0Z and 12Z) captures diurnal cycles.
Limitations
- Data is temporally stale, with the last update recorded in 2007.
- Spatial resolution is coarse at 2° latitude by 10° longitude.
