I have a lot of precipitation raster data (more 5000 files), created by kriging interpolation. All grid cells have the same size and the maps the same spacial extent  I want merge all data in NetCDF. How can I do that?

Can you help me?

have you explored the multidimensional toolset? which covers various ways of dealing with/producing netcdf files within arcmap

An overview of the Multidimension toolbox—Help | ArcGIS for Desktop

scipy and numpy handle netcdf as well since they are multidimensional by default... so you have many options

ie scipy.io.netcdf.netcdf_file — SciPy v0.14.0 Reference Guide

and scipy and numpy are delivered with arcmap and aprgis Pro (recent versions in any event)

EDIT

you may find this interesting as well 6,000+ rasters the follow-up

Yes, tried, but I can´t merge all data into NetCDF. Maybe, do you have a tutorial step by step.

the tutorial is linked in the help files

You should bookmark this link to make it easier to search for materials for both arcmap and pro

good luck

Thanks I checked, but ArcGIS has tools for read NetCDF, I don not see tools for created. Raster To NetCDF does not work with many files (more 5000). If you have a tutorial for create NetCDF from raster data, welcome. Thanks.

You will have to go outside of arcmap and choose your language...there are modules for python etc  You can search pypi

PyPI - the Python Package Index : Python Package Index  or GitHub How people build software · GitHub if a standard web search has turned up nothing.
