Global grid of number of growing days based on temperature and precipitation constraints, as well as potential for pest damage. Native resolution is 0.5° projected in Geographic Coordinate System WGS 1984
1. In ArcMap 10.0, convert native data to 30 arc second resolution.
2. Extrapolate existing data using a 30×30 cell rectangular neighborhood.
3. Use zonal statistics to calculate mean values within each GLU.
Data is coded by the number of cells covered by the native data (1), data extrapolation (2), and not covered by either (3).
