Climate Research Tools

My projects on GitHub

Here are packages I have written for processing climate data.

• Python package hn2016_falwa: hn2016_falwa is a python package for implementing the local finite-amplitude Rossby wave activity diagnostic on climate data. This is an analysis technique I proposed in my Ph.D. dissertation. The package is under active maintenance and constantly being updated.

• python-climate-data-processing: A collection of jupyter notebook tutorials (in python 3.6) on Fourier transform, spectral analysis on climate data and visualization using the Cartopy library.

Other blog posts/tutorials

• Bulk download of ERA5 data from CDSAPI

• Python Library and scripts for downloading ERA-Interim Data

• Installing Python Library for downloading ERA-Interim Data

Free online tools for climate data visualization/manipulation

Here are tools I have found online for climate data analysis/visualization.

• Panoply by NASA: data viewer (on maps) of netCDF, HDF and GRIB files; I use it on Windows/macOS.
• NCO toolkit: command-line program to manipulate netCDF files; I often use that on Linux.
