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/
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)
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>
