Hi all, I had proposed this new standard name about half a year ago. It seems everybody participating in the discussion was happy with:
acoustic_signal_roundtrip_travel_time_in_sea_water Canonical units would be seconds. I gather this standard name has not moved beyond the proposal stage yet. Can we make it official now? Matthias ---------------------------------------- From: Lowry, Roy K. rkl at bodc.ac.uk Thu May 30 07:45:54 MDT 2013 Dear All, Of Matthias's suggestions I have a strong preference for a slight extension of roundtrip_acoustic_travel_time_in_sea_water, namely acoustic_signal_roundtrip_travel_time_in_sea_water. 'two-way' is a possible alternative to 'roundtrip' but I think the former carries unfortunate seismic semantic implications, so 'roundtrip' is better for IES. Including 'in_sea_water' is also essential to clearly distinguish it from seismic data. Cheers, Roy. ________________________________________ From: CF-metadata [cf-metadata-bounces at cgd.ucar.edu] On Behalf Of Matthias Lankhorst [mlankhorst at ucsd.edu] Sent: 30 May 2013 13:16 To: cf-metadata at cgd.ucar.edu Subject: [CF-metadata] standard_name for acoustic travel time from echo sounder Dear CF, I have oceanographic data from IES instruments (inverted echo sounder) that I would like to publish via OceanSITES in a CF-compliant form. The data in question are acoustic travel times from the echo sounding device. This means the time it took for the acoustic signal to run from the instrument (which sits on the seafloor) to the sea surface and back to the instrument. These data are commonly used as a proxy for ocean heat content. I don't think there is a suitable CF standard_name out there, and ask for your help in finding/creating one. Which of the following sound good? acoustic_travel_time vertical_acoustic_travel_time roundtrip_acoustic_travel_time_in_sea_water echo_sounder_acoustic_travel_time ...I could think of a couple more combinations using the words above, but would like to hear other people's opinions. The canonical units would obviously be seconds. I assume the data would need some additional description to denote the vertical extent of the measurement, such as cell_bounds and cell_methods='Z:sum'. Any comments?
