Meteorological data such as precipitation, temperature, and evapotranspiration are usually stored in NC format, and the data can be read by Matlab and ArcGIS. Often year by month by day data. When using GIS for data analysis, it needs to be converted into raster data.
(1) Open the nc data. Open GIS, ArcToolbox-Multidimension Tools-Make NetCDF Raster Layer and click OK. Note that the nc file path must be in English.
(2) Right-click the raster layer generated by the imported nc data, select properties-NetCDF-Band Dimension and select time.
(3) If the processed data does not have a defined coordinate system, you need to define the coordinate system of the raster file by yourself. Note that this is the coordinate system that defines the entire data frame instead of the right-click Layers-Properties-Coordinate System-new Project System of the raster layer
. I saved it in tif format here. It can then be used as raster data for subsequent analysis in GIS.
