Decoding all.ggrib
Post by iconPost by Vibredous | 2022-02-03 | 07:24:13

Hi All,

congrats to you Cvetan if you read this. What you've doen is just great.

I decode all.grib using pygrib but cannot find the same output as displayed in VR (or in the Zezo chart). I for sure have a mistake somewhere. Did somebody tried to decode all.grib and could gimme a little help ?

They are not exactly the same because:

- The game has minimum wind speed of 2.0 knots which the real world does not.

- There is rounding error because of the way data is encoded by the game. U/V are represented as integer square roots of the (scaled) real data
