xcesm's Introduction

About xcesm

Xcesm tries to provide an easy-to-use plugin for xarray to better handle CESM output in python.

Features

Xcesm is still in developing, right now it has the following features:

  • quick plot on global map (quickmap)
  • regrid pop output to linear grids (regrid, nearest interpolation)
  • compute global mean (gbmean, gbmeanpop)
  • diagnose AMOC, PRECP, d18O(only support for iCESM), Heat transport etc.
  • truncate ocean as several main basins (ocean_region)

More feature will be added in the future.

How to install

via git

git clone https://github.com/Yefee/xcesm.git
cd xcesm
python setup.py install

How to use

regrid

import xarray as xr
import xcesm
ds = xr.open_dataset('/examples/data/salt.nc')
# defalut to 1x1 degree
salt_rgd = ds.SALT.utils.regrid()

print(ds.SALT.shape)
(384, 320)

print(salt_rgd.shape)
(181, 361)

quick plot

salt_rgd.utils.quickmap()

salt_distribution

And more

I don't have time to write documentation recently, but it will be released in this summer!
