# Overview

PseudoNetCDF provides read, plot, and sometimes write capabilities for atmospheric science data formats including:

* CAMx (www.camx.org)
* RACM2 box-model outputs
* Kinetic Pre-Processor outputs
* ICARTT Data files (ffi1001)
* CMAQ Files
* GEOS-Chem Binary Punch/NetCDF files
* and many more, for a full list of formats see `pncdump --list-formats`

Documentation on PseudoNetCDF is available at https://barronh.github.io/pseudonetcdf

# Example code

Code below needs paths and formats filled in. The format should be chosen from "Current Formats" below.
Note that there are many methods for modifying the files. Use `help` on infile to learn more options.

```
import PseudoNetCDF as pnc
inpath = '<path-to-input>'
outpath = '<path-for-output>'
infile = pnc.pncopen(inpath, format = '<choose-format-below>')
# Print CDL representation - good for learning dimensions, variables, and properties
print(infile)
# Optionally, add dimension slicing
# infile = infile.sliceDimensions(<layer-dim-name> = 0)
# infile = infile.applyAlongDimenions(<time-dim-name> = 'mean')
# patches = infile.plot('<varkey>', plottype = 'longitude-latitude')
# patches.axes.figure.savefig('<path-for-figure>')
infile.save(outpath)
```

# Example Command Line Interfaces

pncdump - like ncdump
pncgen - reads from a file and generates a netcdf file
pncload - read in a file and open a python environment

```
$ pncdump -f <choose-format-below> <path-to-input>
$ pncgen -f <choose-format-below> <path-to-input> <path-to-output>
$ pncload -f <choose-format-below> <path-to-input>
```
