NetCDF又称科学数据集，可以存储温度、湿度、风速、风向等多个维度的文件格式。

1、在ArcMap中显示NetCDF数据

ArcMap不能直接读取NetCDF数据，需要使用GP工具Make NetCDF Raster Layer(创建NetCDF栅格图层)，将NetCDF生成栅格图层。

2、显示特定年份的温度图层

方式一：直接在图层属性中设置。

方式二：使用GP工具Select by Dimention(按维度选择)。

3、按照时间动态展示数据

首先对图层启用时间，然后打开时间滑块。

4、按照年份，导出NetCDF的每幅栅格

1)设置NetCDF图层的波段维度为Year。

2)复制这里→(https://pan.baidu.com/s/1acJB6v9RqyMqmWuqVENzwA?errno=0&errmsg=Auth%20Login%20Sucess&&bduss=&ssnerror=0&traceid=#list/path=%2F)下载，NetCDF_time_slice_to_Raster.zip，解压后，添加到目录窗口中，然后运行工具。

生成结果是以Band_命名的。我们可以稍微改下代码，以年份命名。打开脚本方法如下：

修改后的脚本如下：

1. # -------------------------------------------------------------------

2. # export_netCDF_slice.py

3. # Created on: 2011-06-02 10:18:49.00000

4. # Description: This scipt will create a TIFF raster from a NetCDF layer, and

5. # save each band of that TIFF as a seperate TIF raster (for each time slcie in a netcdf file) 

6. # -------------------------------------------------------------------

8. # Import modules

9. import arcpy, os

11. #Inputs

12. Input_NetCDF_layer = arcpy.GetParameterAsText(0)

13. Output_Folder = arcpy.GetParameterAsText(1)

15. Input_Name = Input_NetCDF_layer

16. Output_Raster = Output_Folder + os.sep + "NetCDF_Raster.tif"

18. #Copy the NetCDF layer as a TIF file. 

19. arcpy.CopyRaster_management(Input_Name, Output_Raster)

20. arcpy.AddMessage(Output_Raster + " " + "created from NetCDF layer")

22. #Reading number of band information from saved TIF

23. bandcount = arcpy.GetRasterProperties_management (Output_Raster, "BANDCOUNT") 

24. resultValue = bandcount.getOutput(0)

26. count = 1

28. # Year

29. yearN = 1875

31. arcpy.AddMessage("Exporting individual bands from" + Output_Raster)

33. #Loop through the bands and copy bands as a seperate TIF file.

34. while count <= int(resultValue):

35.     Input_Raster_Name = Output_Raster + os.sep+ "Band_" + str(count)

36.     Output_Band = Output_Folder + os.sep +  str(yearN) +".tif"

37.     arcpy.CopyRaster_management(Input_Raster_Name, Output_Band)

38.     arcpy.AddMessage("Band_" + str(count) +".tif" + " " "exported" + " " + "successfully")

39.     yearN +=5

40.     count +=1

43. # The following will delete the TIFF file that was created by CopyRaster tool.  

44. arcpy.Delete_management(Output_Raster,"#")

46. arcpy.AddMessage("Tool Executed Successfully")
