关于调用tcorr报错：Data Request Error: Invalid grid coordinates

• 调用tcorr求中亚地区夏季降水指数与前期4-5月土壤湿度的关系时出现下图错误
• 
• 脚本如下：

• 不明白Data Request Error: Invalid grid coordinates
    World coordinates convert to non-integer  grid coordinates是什么问题
• 本人grads新手小白一枚，希望各位大神帮我看一下出现图中错误的原因，感激不尽！！

是不是打开的三个文件维度不一样，导致air2这个变量读取的时候出了问题
