使用 CDO 在 R 中重新排列多個 netcdf 文件

Question

我需要重新網格化數百個 netCDF 文件，但是當我在 R 中使用 CDO 命令時，總是出現這樣的問題：

cdo remapnn (Abort): Too few streams specified! Operator needs 1 input and 1 output streams.

代碼如下：

files <- list.files(path = common_path,pattern = ".nc")
cdo_path   = '/opt/local/bin/cdo'

new_data_folder = "test_r"
raw_data_folder = "data"

for (i_file in files) {
  raw_file <- paste(raw_data_folder,i_file,sep = '/')
  new_file <- paste(new_data_folder,i_file,sep = '/')
  system(paste(cdo_path,' remapnn,r720x360 ',raw_file,new_file,sep="")) 
}

Answer 1

你可以試試這個：

system(paste(cdo_path,' remapnn,r720x360 ',raw_file,' ',new_file,sep = ""))
