Rainfall studies using Netcdf data

Question

Hi all. I am currently doing a rainfall study using Netcdf data. I would like to know how I can make a graph using a Netcdf raster layer in Arcgis or MS Excel? The Netcdf raster layer does not appear to be applicable for creating a graph in Arcgis. Also the Netcdf raster layer does not appear to have an attribute table when viewed in Arcgis. I would really appreciate your assistance with this problem.

I would have to know what the grid contains.  If the data are integer, then it would have been converted to an integer grid where each Value potentiall represents a class and the Count field is the number of cells within that class.  So without knowing what went into the original file, it is difficult to comment.  Check documentation for the NetCDF files and see what the data really represents.  I somewhat doubt that they represent actual rainfall values, but some sort of classed data.

Thanks Dan. I managed to convert the Netcdf Raster to an Esri Grid format. The output was the raster dataset, as desired. As I mentioned before my goal is  to create a graph, particularly a graph illustrating the rainfall magnitudes in a particular area. The Esri Grid consisted of several fields, and so I am not too sure which one is the most applicable field for constructing the graph. Do you by any chance have an idea of how to solve this problem? I would really appreciate your assistance, if possible. Thank You.

If the data are floating point, it won't have an attribute table.  Try converting it to an Esri grid first
