Sure. I bundle a small rectangle of neighbouring locations like 5x5 (= 25 locations). The actual weather model may have a grid like 2878x1441 cells (4 million). Inside the 5x5 chunk, I subtract all grid-cells from the center grid-cell. The borders will then contain only the difference to the center grid-cell. Because the values of neighbouring grid-cells are similar, the resulting deltas are very small and better compressible. |
