Welcome to the Earthdata Forum! Here, the scientific user community and subject matter experts from NASA Distributed Active Archive Centers (DAACs), and other contributors, discuss research needs, data, and data applications.
The NASA Global Change Master Directory (GCMD) staff is pleased to announce the release of the GCMD keywords version 12.0. Version 12.0 of the keywords consists of new and revised Ocean keywords to more closely align with the NOAA Technology, Planning, and Integration for Observation (TPIO) keywords and based on a community review conducted through NASA's Earth Science Data and Information Systems (ESDIS) Standards Office (ESO). Based on the review, there were 61 new keywords and 8 revised keywords. The revised keyword paths included moving 'OCEAN SALINITY BUDGET' to be under 'OCEAN SALINITY'. Since there were no collection records with these keywords, there is no user impact. 5 additional new keywords were added based on requests from the keyword community.

I do not understand the recent changes to SEA SURFACE TOPOGRAPHY keywords in version 12. Sea Surface Topography is the measurement of the height of the ocean above the geoid (see NASA's own page https://science.nasa.gov/earth-science/ ... topography for reference). It has nothing to do with sea ice. But all of the SEA SURFACE TOPOGRAPHY keywords have been changed to be under SEA ICE, for example:

By the way, that change seems to also have removed the "EARTH SCIENCE > OCEANS > SEA SURFACE TOPOGRAPHY > SEA SURFACE HEIGHT" keyword, which was used for all of the Jason-1, Jason-2/OSTM, and Jason-3 missions. Can that keyword be restored?
Thank you John. We are currently investigating an issue that prevents us from republishing the most recent update of the keywords. We will let you know when that is resolved. Thank you for your patience.
