Native HYDE cropland country conservation across seven CE labels¶
The 84-row result sums the release's
cropland<year>AD.asc grids at 500, 1000, 1500, 1700, 1900, 2000 and
2025 CE over cells labeled Denmark, Finland, Norway or Sweden by its own
iso_cr.asc country grid. Each year is checked separately for base, lower and
upper scenarios. The report pins the general ISO archive, all
21 scenario/year archives and the three source country tables by SHA-256. ZIP
member occurrences must be unique and each native grid must have the same six
header declarations and all 2,160 rows of 4,320 cells.
| Country | ISO grid cells | Base 2000 CE cropland km² | Largest absolute grid–table difference across seven years and three scenarios, km² |
|---|---|---|---|
| Denmark | 1,103 | 22,884.872 | 0.0000000000274 |
| Finland | 9,161 | 21,920.000 | 0.0000000000851 |
| Norway | 9,699 | 8,840.000 | 0.0000000000138 |
| Sweden | 11,504 | 26,022.000 | 0.0000000000795 |
Every selected ISO cell has a finite nonnegative cropland value in all three scenarios at all seven labels. Decimal sums agree with the source-reported country totals to better than 0.000001 km²; the tiny differences are consistent with source numeric rounding. Source zero cells remain counted as zeros, and country cell totals are not mistaken for land area. The country-year study supplies the matched country totals and their source interpretation.
This verifies native grid-to-country reconciliation for cropland at seven selected CE labels. It does not establish the formal CRS, translate HYDE time to BP, resolve the release's rights/version conflicts, admit other variables or every source year, or turn modeled land use into independent vegetation truth. The lower and upper source scenarios remain alternative model outputs, not uncertainty intervals.
