2003 data from NASA EarthData provides geospatial statistics on internal wave packets extracted from Synthetic Aperture Radar (SAR) imagery over Massachusetts Bay. The dataset, sourced from NOAA NCEI, contains polygons representing 1x1 minute latitude/longitude grid cells with calculated statistical metrics for each cell. It was created to analyze the frequency, size, and location of these oceanographic features.
Use Cases
- Analyzing the relationship between internal wave packet frequency and geographic location using the gridded polygon data.
- Modeling the distribution of internal wave packet sizes by training on the average, minimum, maximum, and variance of packet area statistics per grid cell.
- Correlating oceanographic conditions with internal wave activity by using the total internal wave packet area metric as a target variable.
- Detecting anomalies in wave packet characteristics by applying statistical methods to the standard deviation of internal wave packet areas across the grid.
Strengths
- Data is derived from authoritative Synthetic Aperture Radar (SAR) satellite imagery.
- Statistics are calculated per 1x1 minute latitude/longitude grid cell, providing a standardized spatial analysis unit.
Limitations
- Temporal coverage is limited to a single snapshot from 2003, offering no time-series analysis.
- The spatial scope is restricted solely to Massachusetts Bay, limiting generalizability.
- Sample size and total row count are unknown, preventing assessment of statistical power.
