Jason-3 Wet Path Delay Correction for Sea Surface Height Observations

Historical Jason-3 satellite observations reprocessed to GDR-F standards. This supplementary product provides wet tropospheric corrections computed using the method of Brown et al. (2012) by comparing AMR brightness temperatures with independent SSMIS satellite data. The corrections aim to reduce errors in global sea level change estimates by 2-3 mm over 8 years.

Use Cases

• Correcting Jason-3 sea surface height observations based on supplementary wet tropospheric corrections.
• Improving estimates of global sea level change based on the described 2-3 mm error reduction over 8 years.
• Applying pass-by-pass corrections to historical Jason-3 data as described in the product documentation.
• Analyzing satellite altimetry accuracy by comparing AMR and SSMIS brightness temperature data.

Strengths

• Correction method is based on a published scientific approach (Brown et al., 2012).
• Correction aims to reduce errors in global sea level change estimates by 2-3 mm over 8 years.
• Data is sourced from authoritative satellite instruments (AMR and SSMIS) and NOAA Climate Data Records.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The correction is supplementary and not included in the primary GDR-F product release.
