PseudoNetCDF like NetCDF except for many scientific format backends

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://pseudonetcdf.readthedocs.io/

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>
