Description
The Neighborhood Time Step value provided is not numeric, is less than 1, or is larger than the total number of time steps in the Input Space Time Cube parameter .
Solution
Determine the number of time steps associated with the Input Space Time Cube value and provide a value smaller than that number (not more than 75 percent of the total number of time steps) but no smaller than 1. Details, including the total number of time steps, are written as messages when the cube is created (using Create Space Time Cube). You can also access cube dimensions by entering the following code in the Python window:
import arcpy
in_netcdf = "c:/working/fire.nc"
nc_fp = arcpy.NetCDFFileProperties(in_netcdf)
print("\tSize of the time dimension:
{0}".format(nc_fp.getDimensionSize('time')))
