GES DISC Request for 2 Project Keywords

[ezamkoff]

GES DISC would like 2 new Project keywords:

GEOS
Legacy Data Recovery

Description: GEOS (note that the text is taken from our unpublished Platform webpage that we will convert over to be a Project webpage once the keyword is made)

The GEOS (Geodetic Earth Orbiting Satellite) Program developed three satellites for geodetic studies and for satellite-to-satellite tracking. GEOS 1 launched on November 6, 1965, and was a gravity-gradient-stabilized, solar-cell powered spacecraft that carried electronic and geodetic instrumentation. GEOS 1 was also known as Explorer 29. GEOS 2 launched on January 11, 1968, and was identical to the GEOS 1 satellite and was also known as Explorer 36. GEOS 3 launched on April 9, 1975, and was later renamed the Geodynamics Experimental Ocean Satellite. GEOS 3 was an octahedron spacecraft, topped by a truncated pyramid, with a parabolic reflector for a radar altimeter on the flat bottom side.


Description: Legacy Data Recovery

The Legacy Data Recovery presents a miscellaneous collection of data and documents that date from the 1960’s to the early 1980’s. These data and documents are not archived in CMR. Many of these data come from tapes, microfilm, and microfiche that had been stored in the DAAC archives for decades. The data from magnetic tapes were recovered as part of the GES DISC Data Recovery project across many years. These data were not processed or made publicly available, but are available upon request. In 2016 some of the documents were recovered and digitized, but were not processed or made publicly available. The documents are often not related to any one specific mission and may encompass several missions.

Thank you for your keyword request. I will review it and let you know when it is complete.

@ezamkoff

Project keywords should have a short name and long name structure when applicable. For example,
‘ESIP > Earth Science Information Partners’.

GEOS:
Should this project keyword be structured as ‘GEOS > Geodetic Earth Orbiting Satellite’?
Please provide a reference URL for the project keyword.

Legacy Data Recovery:
Do you want to have a short name for this project keyword? It is not required.
Please provide a reference URL for the project keyword.

Thank You.

Jerome and I have been discussing reference links. There really are none except what is on our ges disc website, which will not be long-lived. For now, please use these references. Once the keywords are created I will make new pages on earthdata and then will ask to modify those webpage links to be the earthdata webpages. So for now here are the references:

https://disc.gsfc.nasa.gov/information/mission-project?title=GEOS

https://disc.gsfc.nasa.gov/information/data-preservation?title=Miscellaneous%20Legacy%20Mission%20Preservation%20Documents

For the longname, what you chose is fine:
GEOS > Geodetic Earth Orbiting Satellite

I do not think we need anything else for the legacy data recovery keyword, but I will see if Jerome agrees.

[ezamkoff]

Jerome agrees. Let us know if you have any questions. Thank you!!

@ezamkoff

I added the new project keywords; please review:
GEOS > Geodetic Earth Orbiting Satellite: https://cmr.earthdata.nasa.gov/kms/concept/9d88bf23-ff19-4c27-934e-704edd330b70?format=json&version=draft
Legacy Data Recovery: https://cmr.earthdata.nasa.gov/kms/concept/627312a7-8106-4001-ad11-2b1f69efaa5f?format=json&version=draft

From Jerome:

Now that I look at it my only hesitation (probably my fault and I should have realize it sooner) on the Legacy definition is that it is quite specific to this GES DISC recovery project but has a very general keyword. It may occur at some point that another DAAC does a similar data recovery (like NSIDC recently did with NIMBUS) and may want fit it under this umbrella term rather than create a new keyword themselves.

[GCMD - tstevens]

I can easily update the definition. Do you have a reference for a more generic definition you can point me too?

[ezamkoff]

Jerome and I rewrote the definition to be more generic:

The Legacy Data Recovery presents a miscellaneous collection of data and documents that are not archived in CMR. Many of these data and documents were recovered and digitized from tapes, microfilm, and microfiche that had been stored in the DAAC archives for decades. Many of these artifacts date from the 1960’s to the early 1980’s. Many of these artifacts are not publicly available but can be obtained upon request. The documents are often not related to any one specific mission and may encompass several missions.

[GCMD - tstevens]

Thank you for providing this. I will update it in KMS.
