NMC operationally produced daily gridded analyses for the Northern Hemisphere from August 1963 to December 1972. The dataset includes parameters like upper-level winds, surface temperature, sea-level pressure, tropopause pressure and temperature, and 500mb relative humidity. Data is structured on a 47x51 polar-stereographic grid centered on the North Pole.
Use Cases
- Analyzing trends in sea-level pressure and surface temperature over the 9-year period to study historical weather patterns.
- Training models to predict upper-level wind patterns using gridded pressure and temperature fields.
- Studying tropopause pressure and temperature variability across the polar-stereographic grid for climate research.
- Investigating correlations between 500mb relative humidity and other atmospheric parameters like surface temperature.
Strengths
- Daily temporal resolution provides high-frequency data for analysis.
- Covers a continuous 9-year period from August 1963 to December 1972.
- Data is structured on a consistent 47x51 polar-stereographic spatial grid.
Limitations
- Data is temporally stale, ending in 1972, limiting analysis of recent climate.
- Spatial coverage is limited to the Northern Hemisphere, excluding the Southern Hemisphere.
- Specific row counts, file sizes, and data completeness metrics are unknown.
