I would recommend using [xESMF](https://pangeo-xesmf.readthedocs.io/en/latest/index.html), which is an xarray wrapper of some code specifically written to interpolate from one geospatial grid to another, and knows how to handle periodic coordinates (see the `periodic` flag in [the constructor of the `Regridder` object](https://pangeo-xesmf.readthedocs.io/en/latest/user_api.html#regridder)). It also provides multiple different interpolating methods which, depending on your application, might be more applicable than xarray's options.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1052918815
