NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration数据是netCDF格式,极地投影,这里给出一个数据读取和绘图的示例脚本:
- f = addfile('D:/Temp/nc/seaice_conc_daily_sh_f17_20080830_v02r00.nc')
- data = f['seaice_conc_cdr'][0,:,:]
- #Plot
- axesm(projinfo=f.proj, gridline=True)
- lworld = shaperead('D:/Temp/map/country1.shp')
- geoshow(lworld)
- layer = imshowm(data, 20, cmap='WhBlGrYeRe', proj=f.proj)
- colorbar(layer)
- t = f.gettime(0)
- title('Sea ice concentration (' + t.strftime('%Y-%m-%d') + ')')
