Geos-3 Altimeter Geophysical Data Record 1975-1978

1975 to 1978 data from the Geos-3 satellite altimeter, containing over 5 million sea surface height measurements. The dataset was produced by NOAA/NODC/Laboratory for Satellite Altimetry and includes supporting geophysical information. Measurements are compressed to a 1-per-second rate using a trim mean filter.

Use Cases

• Analyzing historical sea surface height variations from the 'sea surface heights' field.
• Investigating relationships between 'wind speed' and 'sea state' measurements.
• Comparing historical 'Schwiderski ocean tide height' and 'Cartwright solid-tide height' models.
• Studying time-series geophysical data compressed at a 1-per-second rate.

Strengths

• Contains 5,006,956 altimetric sea surface height records.
• Provides multiple supporting geophysical fields like sea state and wind speed.
• Covers a defined 1975-1978 time period from a specific satellite mission.

Limitations

• Corrections for altimeter bias, tropospheric delays, and electromagnetic bias are not included.
• The provided tide and orbit height corrections are described as old and not very accurate.
• Data is stored in a binary format, which may require specialized tools for access.
