        <gco:CharacterString>Note: Metadata for this accession were extracted from a legacy database maintained by the U.S. National Oceanographic Data Center (NODC). The design of the database did not exactly reflect the FGDC Content Standard for Digital Geospatial Metadata (CSDGM).

Principal Investigator (PI) and organization contact information accurately represents all available information from the legacy database at the time that this description was created. However, proper attribution of a PI to a specific institution or the role (submitting or collecting) taken by an institution may not be correct due to inexact mapping between fields in the legacy database and the CSDGM. Due to this uncertainty, the contact information was initially recorded in the Supplemental Information element of the CSDGM description.

To develop more accurate metadata, NCEI reviews metadata for all accessions on an ongoing basis.

Notes:

On March 1, 1984, NASA launched Landsat 5, the agency’s last originally mandated Landsat satellite. Landsat 5 was designed and built at the same time as Landsat 4 and carried the same payload: the Multispectral Scanner System (MSS) and the Thematic Mapper (TM) instruments.

In 1987, the Landsat 5 TDRSS transmitter (Ku-band) failed. This failure made downlinking data acquired outside of the U.S. data acquisition circle (i.e., range of U.S. ground receiving antennas) impossible; Landsat 5 has no on-board data recorder to record acquired data for later downlink.

The MSS instrument was turned off in August of 1995.

In November 2011, the TM instrument stopped acquiring images due to a rapidly degrading electronic component. A few months later, engineers turned the MSS instrument back on, and implemented new capabilities to ingest the raw instrument data at the ground station.
