+# RTOFS NetCDF to GRIB2 Conversion Tool
+
+## 📌 Overview
+This tool provides a modernized, high-performance solution for converting Global RTOFS (Real-Time Ocean Forecast System) NetCDF production files into NCEP-standard GRIB2 format. It replaces the legacy `rtofs_nc2grb2` shell-processing workflow with a single, optimized Fortran 90 binary.
+
+
+
+---
+
+## 🚀 Why This Process is Superior
+
+The legacy `rtofs_nc2grb2` process relied on a fragmented, multi-step pipeline (NetCDF → ncdump → ASCII text → GRIB Packer). This new consolidated approach offers significant advantages:
+
+### 1. Direct Memory Pipeline (Zero Disk Bloat)
+* **Legacy:** Dumped massive NetCDF arrays into intermediate ASCII files (like `fort.20`). For a $4320 \times 3298$ grid, this created gigabytes of temporary disk waste.
+* **Modern:** Uses the `NetCDF-Fortran` interface to stream data directly into memory. Disk I/O is reduced by nearly **95%**, significantly lowering the load on the `/lfs` filesystem.
+
+### 2. Numerical Integrity
+* **Legacy:** Converting floating-point data to ASCII text and back to binary introduced "precision crawl" and rounding errors.
+* **Modern:** Maintains native 32-bit floating-point precision throughout. Mathematical operations (like Celsius-to-Kelvin) are performed using high-speed Fortran array syntax.
+
+### 3. Native HPC Optimization
+* **Legacy:** Relied on `sed`, `awk`, and shell loops which are slow and difficult to scale.
+* **Modern:** A compiled binary using the Intel 19.1 compiler (`-O3`) and the Cray Programming Environment (`ftn`). It is specifically tuned for the **WCOSS2** architecture.
+
+
+

+
+## 🛠 Technical Comparison
+
+| Feature | Legacy Shell Process | New Consolidated Binary |
+| :--- | :--- | :--- |
+| **Logic Flow** | NetCDF ➜ ASCII ➜ GRIB2 | NetCDF ➜ Memory ➜ GRIB2 |
+| **Intermediate Files** | Massive `.txt` / `fort.XX` | **None** |
+| **Unit Conversion** | External scripts/NCO | Integrated Fortran `WHERE` blocks |
+| **Speed** | Slow (minutes/file) | **Fast (seconds/file)** |
+| **Error Handling** | Silent shell failures | Strict Fortran I/O exception handling |
+
+---
+
+## 📂 Components
+
+| File | Description |
+| :--- | :--- |
+| `rtofs_nc_to_grib2.f90` | The core Fortran 90 source code. |
+| `compile.sh` | Shell script to build the binary with correct library links. |
+| `run_rtofs_grib.sh` | Execution script that handles environment modules and input. |
+
