Version	5.1
Processing Level	2
Start/Stop Date	1992-Sep-25 to Present
Short Name	MERGED_TP_J1_OSTM_OST_ALL_V51
Description	This dataset contains along track Sea Surface Height Anomalies (SSHA) from the TOPEX/Poseidon, Jason-1, OSTM/Jason-2, and Jason-3 missions geo-referenced to a mean reference orbit. Altimeter data from the multi-mission Geophysical Data Records (GDRs) have been 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. Version 5.1 updates include the integration of Jason-3 GDR_F data, and the application of revised (GDR_F standard) internal tides and pole tide across missions. The data are in netCDF format and start in September 1992. Data extensions are appended to the file quarterly. More information on data processing standards can be found in the v5.1 User Handbook (Integrated Multi-Mission Ocean Altimeter Data for Climate Research TOPEX/Poseidon, Jason-1, 2, & 3 Users Handbook: https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/merged_alt/open/L2/TP_J1_OSTM/docs/v100721.version5.1multialthandbook.pdf ). This collection is the same data as https://doi.org/10.5067/ALTCY-TJA51 but all individual cycles are combined into one NetCDF file.

Bucket/Object Prefix: Protected buckets contain the data files for a given collection. Protected simply means users must log in to Earthdata Login before gaining access to contents within that S3 Bucket. Please use the S3Credential endpoint to gain an Earthdata login token for use in S3 Access. Public buckets, in contrast, house metadata such as checksums, imagery, and metadata files and the like. A user can access public buckets and these types of files without logging in to Earthdata Login. Most of the time, you'll want to access the protected bucket Information
