engage with STAC community on forecast extension #11

Open tomkralidis opened 2 years ago

tomkralidis commented 2 years ago

As discussed at MetOceanDWG 2022-08-18, the STAC community has started to build out a forecast extension at https://github.com/stac-extensions/forecast. It will be valuable for us to engage with this activity so the extension leverages concepts and lessons learned, and that MetOcean is able support as part of STAC workflows.

@tomkralidis I think the main lesson from decades of experience is that forecasts are nothing special - there are also hindcasts, nowcasts, analyses, re-analyses etc. They are just observations/measurements/estimates that happen to be in the local future. When I became a meteorologist in XXXX [Redacted ;-)], observations, analyses, forecasts, radar imagery, staellite imagery, etc were all in their own silos and ecosystems. For example, nowadays, there is no reason not to display a temperature field (forecast or observed) like a satellite image. The second lesson is that data/products etc may need to have several times/dates attached to them for various reasons. E.g. start and end times of a radiosonde ascent nominally at 12:00Z. That is 3 times, but it is straightforward to attach 7 different times to a traditional NWP forecast.
