python - 从 THREDDS Catalouge for NetCDF 更改数据源

Question

嗨，我正在使用此处的代码How to read NetCDF file and write to CSV using Python我希望能够从此处的 THREDDS 目录中提取“Mean_period_of_swell_waves_ordered_sequence_of_data”，但收到以下错误。我正在使用天篷

任何想法为什么？谢谢亚历克

Answer 1

通过更改修复

var = nc.variables[vname]
hs = var[istart:istop,iy,ix]
tim = dtime[istart:istop]

至

var = nc.variables[vname]
tp = var[istart:istop,iy,ix]
tim = dtime[istart:istop]
