如何使用R将Grib1转换为Netcdf? [英] how to convert Grib1 to Netcdf using R?

问题描述

我刚刚下载了一些grib格式的气候数据.我想使用"R"将其转换为NetCDF格式.

I have just downloaded some climate data in grib format. I want to use "R" to convert it to NetCDF format.

此外，由于文件由不同的变量组成，我想一次将一个变量提取到单个文件中.

Furthermore, as the file consists of different variables, I would like to extract one variable at a time into individual files.

推荐答案

如果没有您的特定文件，很难回答这个问题.您应该考虑制作可复制的示例，尤其是如果您重新发布到R板.

It's hard to answer this without your specific file. You should look into producing reproducible examples, especially if you're posting to the R board.

对于R，签出library(raster)和library(ncdf4).我只是获取了我看到的第一个grib1文件，并整理了一个简单的示例.

For R, check out library(raster) and library(ncdf4). I just grabbed the first grib1 file I saw, and put together a quick example.

library(raster)
library(ncdf4)

download.file(url = 'ftp://ftp.hpc.ncep.noaa.gov/grib/20130815/p06m_2013081500f030.grb', destfile = 'test.grb')

(r <- raster('test.grb'))

n <- writeRaster(r, filename = 'netcdf_in_youR_comp.nc', overwrite = TRUE)
