对T639数据(见附件)解码后,可以生成CTL和idx文件,其中CTL文件中的产品主要有如下23种:
APCPsfc 0 61,1,0 ** surface Totalprecipitation [kg/m^2] DEPRprs 3 18,100,0 **(profile) Dew point depression [K] EPOTprs 3 14,100,0 **(profile) Pseudo-adiabatic pot. temp.

问题:在用GRADS 画图时,对于红色字体标注的产品都为3个层次(500、700、850),但画图的时候只能画出850hPa的,500和700hPa的画不出,不知道具体原因何在,请高手赐教!谢谢
附件为T639的一个数据文件
