## Introduction

NOAA/NWS Meteorological Development Lab ([MDL](https://www.weather.gov/mdl/)) produces model output statistics (MOS) for a variety of NOAA/NCEP Numerical Weather Prediction (NWP) models.  MOS is produced via MDL's in-house MOS-2000 (MOS2K) Fortran-based software system.  MOS2K uses a GRIB-like binary data format called TDLPACK.  `pytdlpack` is a Python interface to reading and writing TDLPACK files.  A brief introduction to TDLPACK files and data format can be found [here](TDLPACK.md).

## Motivation

Provide a Python interface for reading and writing TDLPACK files.

## Requirements

* Python 3.6+

* setuptools 34.0+

* NumPy 1.12+

* GNU or Intel Fortran compiler

## Installation

```shell

pip3 install pytdlpack

```

### Build and Install from Source

```shell

python3 setup.py build_ext --fcompiler=[gnu95|intelem] build

python3 setup.py install [--user |--prefix=PREFIX]

```

## Modules

The pytdlpack package contains 2 modules.  See the docstrings for usage of each module

### pytdlpack

```python

import pytdlpack

```

### TdlpackIO

```python

import TdlpackIO

```

**IMPORTANT:** ```TdlpackIO``` is **experimental** and it usage and functionality could change with future releases.  TdlpackIO is a pure python implementation for reading TDLPACK "sequential" files (i.e. Fortran variable-length record binary files).  Currently, it does not read TDLPACK random-access files and it may never have that capability.  It requires ```pytdlpack``` for unpacking records.
