因此，请您提供一些信息，以了解如何在R中将其转换为netcdf。
答案 0 :(得分：0)
软件包ncdf4将帮助您实现这一目标。这是documentation，用于通过定义数据框的尺寸和变量来创建netCDF文件。
这是我尝试创建3维netCDF的示例代码。
使用的数据：
lat,long,time
41,-109,6
40,-107,18
39,-105,6
41,-103,18
40,-109,6
39,-107,18
示例代码：
library(ncdf4)
#Collect individual columns
xvals <- df$long
yvals <- df$lat
time <- df$time
#Create dimension definition
lon_dim <- ncdim_def("longitude", "degrees_east", xvals)
lat_dim <- ncdim_def("latitude", "degrees_north", yvals)
time_dim <- ncdim_def("time","h",unique(time))
#Define new variable and append with 0
mv = 1.e30
frp <- ncvar_def("frp", "frp", list(lon1,lat2,time_dim), mv)
frp
#Create a netCDF file
ncnew = nc_create("C:\\Users\\Desktop\\my_nc.nc", frp)
ncnew
您可以使用ncvar_put函数添加frp的值。该文档干净准确。应该会有所帮助。希望这能回答您的问题。
