You’re likely hitting the 2 GB file size limit, common in Fortran-based programs like HYSPLIT’s cluster.exe. Many 32-bit or default-compiled Fortran binaries stop writing unformatted output once the file exceeds ~2.1 GB. That would explain why the CLUSTER file stops, despite the process completing without error and DELPCT data being available.
You may split your clustering runs (e.g., by decade) to stay within safe file size limits, and recompile cluster.exe using a 64-bit Fortran compiler with large file support enabled (e.g., -fdefault-integer-8, -D_FILE_OFFSET_BITS=64).
Consider enabling alternate output formats (e.g., binary or NetCDF) for more scalable post-processing.
