Background
- The old DROUGHT-BOM-GRIDS data came from a Barnes IDW algorithm, at 25km (actually 0.25 decimal degrees) resolution
- 1890-2008
- Going forward the AWAP grids are Preferred
- this is a quick and dirty approach
Methods
- AWAP grids are 5km (0.05 dd) but this will take longer to process and is probably overkill for monthly total rainfall when focus is on drought
- For the centroid point of each 0.25 dd extract the data value (might be better to take mean of sub-cells within each, plan for future)
- compare this with old BOM GRIDS
Results
compare with bom grids for Jan 2000
