Description
The NASA JASON-1 Project provides enhanced Microwave Radiometer corrections and Geophysical Data Records from the Jason-1 altimetric satellite mission. The data contain direct observations of altimeter range, significant wave height, wind speed, and tropospheric water content, used to calculate Sea Surface Height Anomalies. The dataset is hosted on AWS Open Data and is licensed under CC-BY-4.0.
Use Cases
Calculating coastal Sea Surface Height Anomalies based on enhanced wet tropospheric path delay corrections.
Analyzing ocean wind speed patterns based on radar backscatter cross-section measurements.
Studying wave climate using significant wave height observations from the altimeter.
Correcting satellite altimetry data for ionospheric and tropospheric effects mentioned in the description.
Strengths
Provides enhanced corrections for coastal regions, offering better accuracy than standard Geophysical Data Records.
Contains direct observations from multiple satellite instruments, including altimeter range and significant wave height.
Data is provided in the NetCDF format, which is standard for geospatial and scientific data.
Limitations
Row count and dataset size are unknown, which may limit suitability assessment.
Column-level documentation is absent; field semantics must be inferred after download.
Last update date is unknown; freshness unverified.
