如题，我在http://bbs.06climate.com/forum.php?mod=viewthread&tid=5363 贴中也问了差不多的问题，至今尚未得到解决。虽然http://bbs.06climate.com/forum.php?mod=viewthread&tid=2663 贴中的楼主luoziwuhui虽然提供了一个方法，但是一直忽略了后面一大堆人回帖提问的关于地形数据的分辨率的问题。即，他提供的地形分辨率太低，才2.5°×2.5°，垂直方向才12层，无法满足目前较高分辨率数据画图的需求。更不用说我用WRF模拟出来的4公里分辨率的数据了！
所以，我想问问论坛里的高手，我用ARWpost来生成的数据ctl 为如下，能画大概如下图类似的地形覆盖的图吗？
我的数据的ctl 如下：
