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）点击这里下载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：

# Description: This scipt will create a TIFF raster from a NetCDF layer, and
# save each band of that TIFF as a seperate TIF raster (for each time slcie in a netcdf file)

# Import modules
import arcpy, os

Input_NetCDF_layer = arcpy.GetParameterAsText(0)
Output_Folder = arcpy.GetParameterAsText(1)

#Copy the NetCDF layer as a TIF file.
arcpy.CopyRaster_management(Input_Name, Output_Raster)
arcpy.AddMessage(Output_Raster + " " + "created from NetCDF layer")
#Reading number of band information from saved TIF
bandcount = arcpy.GetRasterProperties_management (Output_Raster, "BANDCOUNT")
resultValue = bandcount.getOutput(0)
count = 1
# Year
yearN = 1875
arcpy.AddMessage("Exporting individual bands from" + Output_Raster)
#Loop through the bands and copy bands as a seperate TIF file.
while count <= int(resultValue):
Input_Raster_Name = Output_Raster + os.sep+ "Band_" + str(count)
Output_Band = Output_Folder + os.sep + str(yearN) +".tif"
arcpy.CopyRaster_management(Input_Raster_Name, Output_Band)
arcpy.AddMessage("Band_" + str(count) +".tif" + " " "exported" + " " + "successfully")
yearN +=5
count +=1
# The following will delete the TIFF file that was created by CopyRaster tool.
arcpy.Delete_management(Output_Raster,"#")
arcpy.AddMessage("Tool Executed Successfully")
