Message cell_methods' time interval on UK Deterministic Model SQS #8

Closed fepeacock70 closed 5 years ago

fepeacock70 commented 5 years ago

Hello,

For periods of 3 hourly data on the 03Z and 15Z UK Deterministic runs, the SQS messages have cell_methods with time interval of 1 hour rather than 3 hours.

Hi @fepeacock70 - thanks for the feedback.

The "cell_methods" attribute is taken directly from the NetCDF Climate and Forecasting metadata conventions. As such, the "interval" value is only refering to the spacing of the original data, it is not the time range relevant to a particular file.

To determine the time range(s) relevant to a particular file you may want to try the "forecast_period" and "forecast_period_bounds" attributes.

Thanks Richard. I did notice that the "forecast_period_bounds" attribute reflected the true time period.
