Source Grid Setup

How to set up the source grid for remapping.

Overview

The source grid defines the spatial representation of the data to be remapped. It can be created from various grid types, such as latitude-longitude grids, MPAS meshes, or projected grids.

Methods

• src_from_lon_lat: Create a source grid from latitude and longitude arrays.

• src_from_mpas: Create a source grid from an MPAS mesh file.

• src_from_proj: Create a source grid from a projected grid.

Example

from pyremap import Remapper

remapper = Remapper()
remapper.src_from_lon_lat(lat, lon)

Setting Source Descriptor Directly

The src_descriptor attribute can be set directly to define the source grid. This is useful when you already have a pre-defined grid descriptor or need additional capabilities not provided in the src_from_*() methods.

Example

from pyremap import Remapper, LatLonGridDescriptor

lat_lon_descriptor = LatLonGridDescriptor.read(file_name='grid_file.nc')
remapper = Remapper()
remapper.src_descriptor = lat_lon_descriptor
