A high-altitude weather satellite transmits atmospheric scan data in a compact binary format.
The table below shows the atmospheric classification levels and their corresponding 4-bit binary representations:
| Classification | Binary value |
|---|---|
| Clear | 0010 |
| Light Cloud | 1100 |
| Dense Cloud | 0111 |
| Storm | 1001 |
The metadata header indicates that the scanned area has a width of 5 pixels and a height of 3 pixels.
The raw binary stream representing the pixel grid of the scan is:
001000101100011100101100011110010111110000100010001011000111
The scan data starts at the top-left corner and is processed left-to-right, row-by-row.
Complete the table below by writing the atmospheric classification that each pixel in the 5×3 5 \times 3\,5×3 grid will display.
