使用 R 将数据写入 netCDF 文件

我正在尝试使用我自己的 .csv 文件中的数据来使用 R 包“ncdf4”创建 netCDF 文件。 我的数据集由 3 列组成：经度、纬度和温度，有 2592 行。 我一直按照包中的建议将维度和变量添加到 netCDF 文件中。一切都很顺利，直到我想将温度数据写入我的文件。 我收到这个错误：

Error in ncvar_put(nc = ncnew, varid = var_temp, data, start = c(1, 1,  : 
  ncvar_put: error: you asked to write 65160 values, but the passed data 
  array only has 2592 entries! 

怎么了？

library(ncdf)
library(ncdf4)

TimeTable<-read.csv("time.csv",header=T,sep=",")
filename="time.nc"

xvals<-1:360
yvals<--90:90
nx<-length(xvals)
ny<-length(yvals)
lon1<-ncdim_def("longitude","degrees_east",xvals)
lat2<-ncdim_def("latitude", "degrees_north",yvals )

time<-ncdim_def("Time","months", 1:12, unlim=T )
mv <- -999 # missing value to use
var_temp<- ncvar_def("temperature", "celsius", list(lon1, lat2, time),longname="CRU_Global_1961-1990_Mean_Monthly_Surface_Temperature_Climatology",mv) 


ncnew<-nc_create(filename,list(var_temp))

print(paste("The file has",ncnew$nvars,"variables"))# 
print(paste("The file has",ncnew$ndim,"dimensions"))# 

data<-array(TimeTable$tem_1)
ncvar_put( nc=ncnew, varid=var_temp,data,start=c(1,1,1),count=c(nx,ny,1))

你能给我推荐一些东西吗？ 非常感谢

# Some fake dataset based on latitude, to check whether the data are
# written in the correct order
data <- rep(yvals, each=nx)

# Add random -999 value to check whether missing values are correctly
# written
data[sample(1:(nx*ny), 100, replace = FALSE)] <- -999
ncvar_put(ncnew, var_temp, data, start=c(1,1,1), count=c(nx,ny,1))

# Don't forget to close the file
nc_close(ncnew)

# Verification

out <- raster("time.nc")
levelplot(out, margin=FALSE)
