Description
The Neighborhood Time Step value provided is larger than 75 percent of the total number of time steps in the Input Space Time Cube parameter.
Solution
Provide a smaller value for the Neighborhood Time Step parameter: no smaller than 1 and no larger than 75 percent of the total number of time steps in the Input Space Time Cube parameter. 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')))
