Include NWPs at multiple altitudes #5

Open JackKelly opened 3 years ago

JackKelly commented 3 years ago

Detailed Description

The NWP conversion script I'm working on in openclimatefix/nowcasting_dataset#344 will, for now, only convert the same NWPs we've used in the past (NWPs at the Earth's surface)

At some point, we should also experiment with NWPs at altitude (e.g. temperature and humidity at cloud altitude).

Context

NWPs at cloud altitude may help our models figure out when clouds are likely to appear / disappear.

But it's a lot more data.

Possible Implementation

The UKV NWPs have something like 70 vertical levels. We probably don't need all those. Maybe we could compute the mean for three vertical levels: 0 to 3.3 km; 3.3 km to 6.6 km; 6.6 km to 10 km.

Priority

I'll put this into WP1 for now as a "nice to have"... but this may have to wait until WP2.
