Jonathan, There is an associated convention, the Attribute Convention for Dataset Discovery (ACDD) that defines file-level attributes detailing things like time_coverage_resolution. The issue of high-rate time dat

Seth & Roy, Technically CF-compliant but “unconventional” is probably not the way to go, as I’d miss out on the tools that use the convention, which is the point of using the standard. I think I just needed someone to help me navigate the CF documents, as they’re rather dense and unfamiliar:-)

Hi Jonathan, Oh, climate model outputs are also supposed to have a uniform sample rate for the whole time series -- emphasis on *SUPPOSED TO*. To my dismay, I have encountered multiple cases where something went wrong with the generation of the data files, resulting in missing or repeated or weir

Hi Seth, Thanks for the very helpful response. I can understand the argument for explicit coordinates, as opposed to using formulae; I think it solves several problems. The assumption of a uniform sample rate for the length of a continuous time series is deeply engrained in most seismic softw

Hi Jonathan, I would interpret the CF stance as being that the value in having explicit coordinate variables and other ancillary data to accompany the data outweighs the cost of increased storage. There are some cases where CF bends away from that for the sake of practicality (see, e.g., the disc

Hi all, I’m curious about the suitability of CF metadata conventions for seismic sensor data. I’ve done a bit of searching, but can’t find any mention of how CF conventions would store high sample-rate data sensor data. I do see descriptions of time series conventions, where hourly or daily s
