vertical interpolation onto a tracer coordinate

6

I love the high-level API of this package and it's efficient. There are lots of geoscience applications that need vertical-coordinate transformation, like converting the pressure-level data to isentropic levels in...

Changing to 0.7.0 causes some problems

2

I run the following code snippet using 0.7.0 version of `xgcm`: ```python import xarray as xr import xgcm from xgcm.autogenerate import generate_grid_ds print(xgcm.__version__) dset = xr.tutorial.open_dataset('air_temperature') ds = generate_grid_ds(dset, {'X':dset.lon,...

interp change the format of time

1

Recently, I update xgcm from 0.5.0 to 0.7.0 and re-run a script doing some diagnostics using outputs from MITgcm. The codes of loading data and assign a new time coordinates...

time-varying bins

4

Thanks to you guys for this handy package. I had to use time-varying bins when I tried to calculate the area enclosed by tracer contours, as the tracer changes with...

overlapping bins

3

`xhistogram` is great tool for one of my project that bins tropical cyclone (TC) records into gridded data as the frequency of occurrence. However, it is done using a non-overlapping...

align a cartopy 2D map plot with a 1D line plot

5

I need to align a cartopy 2D map subplot with a 1D line subplot (zonal-mean or meridional mean of the 2D data), using the following code: ```python import xarray as...

add support for dtype of station data

2

[`GrADS`](http://cola.gmu.edu/grads/gadoc/) support a type of [station data](http://cola.gmu.edu/grads/gadoc/aboutstationdata.html). Not so sure if someone need to read in the station data. Since there is no objective analysis method like [oacres](http://cola.gmu.edu/grads/gadoc/gradfuncoacres.html), plotting the...
