ncmock - NetCDF mock data generator.

Overview

Creates a NetCDF file from command-line arguments. Variables can be any type and filled with data in 5 ways, either a constant, a checker pattern, randoms, linear range, or a sombrero ripple function, all of which can be animated too if they use a record dimension. Specific constants and randoms allowed include positive/negative infinity, NaN, negative zero, minimum denormalized positive for a datatype, and min/max for a datatype. Global and variable attributes can also be created. Advanced controls exist for choosing alignment, blocksize, file flavor (classic or HDF5), prefill, initial size, and header pad. ncmock has throughput and peak memory calipers, so it can also be used as a benchmark tool.

Examples

# Create ripple data animated in time.
ncmock -d x,300 -d y,300 -d t,10,record -v test,f,t,y,x,fun1 -n ripple,fun1,5,5 -p ripple.nc

# Create checkerboard data animated in time.
ncmock -d x,300 -d y,300 -d t,10,record -v test,f,t,y,x,fun1 -n checker,fun1,50,50 -p checker.nc

# Create linear range data animated in time.
ncmock -d x,300 -d y,300 -d t,10,record -v test,f,t,y,x,fun1 -n range,fun1,0,1 -p range.nc

# Create constant fill data.
ncmock -d x,300 -d y,300 -d t,10,record -v test,f,t,y,x,fun1 -n const,fun1,0 -p constant.nc

# Create random data animated in time.
ncmock -d x,300 -d y,300 -d t,10,record -v test,f,t,y,x,fun1 -n rand,fun1 -p random.nc
