FastHerbie forecast times from past or into future?

[andrewsheerin]

Hello,

Before I entirely mess up my project, I want to confirm if forecast times are forecasting into the future from time step X, or are forecasting from the past to time step X. Given the example on the FastHerbie documentation page (screenshot attached).... Does Herbie HRRR model sfc product initialized 2022-Mar-01 00:00 UTC F02 give the forecast for 2022-Mar-01 00:02 or does it give 2022-Feb-28 22:00's two-hour forecast for 2022-Mar-01 00:00?

Thanks,
Andrew

Your first example is correct:

initialized 2022-Mar-01 00:00 UTC F02 give the forecast for 2022-Mar-01 00:02
