Table D sequence for reporting marine observations from autonomous surface vehicles

[david-i-berry]

DISCUSSION

Observations from autonomous surface vehicles are currently converted to BUFR and inserted on to the GTS using the sequence for drifting buoys (315009). However, this sequence is inadequate for the full range of observable parameters and sensors on the surface vehicles. Additionally, the use of the incorrect template leads the observations being mis-attributed to drifting buoys, resulting in the location and platform motion being incorrectly flagged by quality control / assurance systems. The sequence proposed in this document seeks to address these issues.

PROPOSAL
(Details of proposal)
Add new entry to BUFR Table D
Category 15 – Oceanographic report sequences
