NetCDF table views are created in ArcGIS Pro using the Make NetCDF Table View tool. If the project file contains multiple netCDF table views, performance issues may be encountered. The following are the two most common performance issues:
While the project is initializing, ArcGIS Pro recognizes the inclusion of netCDF table views, and re-creates the views, which causes an immediate demand on the system's available RAM. Once the project has finished loading, the C: drive appears to lose space because the netCDF table views are stored in the Local Temp directory which, as a Windows setting default, exists on the C: drive.
Usually, standalone tables serve no particular function to be retained in a project. It is recommended to export the netCDF table views to another disk and delete the views from the project file. This can resolve any performance issues associated with opening the project and reduces space consumption of the Local Temp directory.
Follow the instructions provided below to export the tables to another disk drive and delete the table views from an ArcGIS Pro project.
Warning: The following solution involves modifying the Windows Operating System dependent folder. This is not supported by Esri Support Services.If standalone netCDF table views must be retained in the project file, the increased consumption of the C: drive can be controlled by relocating the Local Temp folder (usually located in C:\Users\<username>\AppData\Local\Temp) to a different drive. For more information, refer to How to Move the TEMP and TMP Directories.
