Hi Stephen
Alison is buried with CMIP5 problems at the moment, so may not get to this query for a wihle. For my tuppence worth, the method by which something is measured should not be in the definition, since the standard name is supposed to be a geophysical quantity, however measured. We've been over this ground other times.
So, I think there is a case to fix the definition here ... (he says, knowing nothing about the ins and outs of this specific example).

One of our data products is the concentration of suspended matter in sea water (TSM). I note that there is a standard name for the same. However, on examining the description for this standard name I discover the phrase 'Determined by filtration, drying and then weighing'.

Could a satellite derived TSM concentration have a standard name concentration_of_suspended_matter_in_sea_water or must a new standard name be devised and proposed that, for instance, includes _from_satellite. Or, rather than proposing a new standard name, would our proposal be to widen the definition of the standard name currently within the table by removing the phrase concerning its measurement.
