Hello Jonathan, I'd go for fluorometer_voltage without the 'ctd' as building in deployment platform information is best avoided, but otherwise I'm with you.
In my experience raw data units may be the same as processed data units (after application of a nominal calibration by the instrument), a voltage, a current or a 'count' (the output from an analogue to digital converter). Dimensionless counts works for me and I think the others are all covered by udunits. Or is there something else out there I've not met? Cheers, Roy. >>> Jonathan Gregory <[email protected]> 03/12/09 9:57 PM >>> Dear Roy That's a good example. I don't really know what it is, of course, but it sounds like it could have a standard name of ctd_fluorometer_voltage and units of V. It seems clear to me to call a spade a spade, rather than to call a spade a raw_garden_implement :-). It's interesting how this discussion is different from the one about isccp and calipso cloud area fraction. In that discussion, I thought that the standard name should be cloud_area_fraction. ISCCP and Calipso are further information about how the quantity is measured, but the quantity itself is a geophysical one, defined independently of the measurement technique. Here, the quantity being named relates specifically to a means of measurement, not to the final product. What are example of non-udunits? V is a udunit, all right. Perhaps a non-udunit is just a count of something? Does that need units? It could simply be regarded as dimensionless.
