Hi , when I used CRU data, i got a error message as following, someone said that it might be caused by the compiler version, my compiler is PGI-7.1-6.(https://lists.ictp.it/pipermail/regcnet/2007/000777.html). Does anyone else know how to solve it ? what  preparation should I do before using CRU data?  please give me a hand. Thank you very much.
