ASCAT CPEX Satellite Wind and Ice Data for Convective Storms

Advanced Scatterometer (ASCAT) CPEX dataset provides satellite-derived estimates of ice probability, wind speed, and wind direction over the ocean surface. NASA collected this data during the Convective Processes Experiment (CPEX) field campaign from May 24 to July 16, 2017, focusing on the North Atlantic-Gulf of America-Caribbean Oceanic region. The data is stored in netCDF-3 format and originates from the MetOp-A and MetOp-B satellites.

Use Cases

• Analyzing convective storm initiation and dissipation by correlating wind patterns with storm events.
• Validating and improving numerical weather prediction models using satellite-derived wind speed and direction measurements.
• Studying ocean-atmosphere interactions by examining wind-roughened ocean surface backscatter data.
• Investigating seasonal ice probability variations in the study region during early summer.

Strengths

• Data originates from a focused NASA field campaign (CPEX) with a clear scientific objective.
• Provides a continuous time series of geophysical variables over a 54-day period in 2017.
• Collected using established satellite radar (ASCAT) technology on operational MetOp platforms.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• Sources conflict on the last updated date, with one reporting 2017 and another reporting a future date of 2026.
