This article mainly introduces "how to achieve the latest climate zoning mask in python". In daily operation, I believe many people have doubts about how to achieve the latest climate zoning mask in python. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to achieve the latest climate zoning mask in python". Next, please follow the editor to study!

Using regionmask mask

Regionmask is a library in Python that is specially used as a geospatial mask.

When selecting the mask area, regionmask can be divided into the following methods:

Regionmask itself defines geographical zones commonly used in scientific literature, including Giorgi, SREX and AR6 using data provided by NaturalEarth to extract national or land regions using numpy or xarray to mask sample data for simple visualization of region of interest data.

AR6 mask geographic partition

Researchers may be more interested in geographical divisions commonly used in the scientific literature, such as the latest AR6 partition, which divides the world into 58 geographical regions, as shown below:

Next, use the AR6 partition to mask the data, select EAS and TIB as the research areas, and mask other irrelevant areas.

Natural Earth masks land and sea

The correlation value is extracted by using the natural erath land information preset by regionmask to achieve the function of masking the ocean, but the resolution here is only 1110, which is relatively rough.

The use of regionmask preset natural erath basin information to extract correlation values to achieve the role of masking land, the default resolution is 1:50.

Customize shp for masking

At this point, the study on "how to achieve the latest climate zoning mask in python" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
