Integrated Multi-Mission Ocean Altimeter Data for Climate Research Version 6.0
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/altcy-tja60
The Integrated Multi-Mission Ocean Altimeter Sea Surface Height (SSH) Version 6.0 dataset provides level 2 along track sea surface height anomalies (SSHA) for 10-day cycles from the TOPEX/Poseidon, Jason-1, OSTM/Jason-2, Jason-3, and Sentinel-6A missions geo-referenced to a mean reference orbit.
Description
It is produced by NASA Sea Surface Height (NASA-SSH) project investigators at Goddard Space Flight Center and Jet Propulsion Laboratory with support from NASA’s Physical Oceanography program, and was developed originally as an Earth System Data Record (ESDR) under the Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, which supported forward processing and incremental refinements through version 5.1 (released in April 2022).
Geophysical Data Records (GDRs) from each altimetry mission were interpolated to a common reference orbit with biases and cross-calibrations applied so that the derived SSHA are consistent between satellites to form a single homogeneous climate data record. The entire multi-mission data record covers the period from September 1992 to present; it is extended to include new observations approximately once each quarter. The current release (version 6.0) applies the following revisions: a) GSFC std2400 orbit for T/P and Jason-1 (cycles 169 – 259), b) JPL_igs20 orbit for Jason-1 (cycles 1 – 168), Jason-2, Jason-3, and Sentinel-6a, c) ITRF2020 terrestrial reference frame, d) Jason-2 GDR_F data, e) Sentinel-6a LR version F09/G01 data through cycle 166, f) GOT5.6D ocean tide model, g) Range latitudinal empirical correction for Jason-1,2, & 3 GDRs.
