Extracting subset from netCDF file using lat/lon and converting into .csv in R
...this dataset using pair of lon and lat
points, e.g., (12.875, -11.625) & (8.875, 4.125) and convert the file into
.csv format.
so far I could make up to this step:
# load the ncdf4 package
library(ncdf4)
# set path and filename
setwd("D:/netcdf")
ncname <- "gfdl_preci"
ncfname <- paste(ncname, ".nc", sep = "")
dname <- "prAdjust"
# open a netCDF file
ncin <- nc_open(ncfname)
print(ncin)# get longitude and latitude
lon <- ncvar_get(ncin,"lon")
nlon <- dim(lon)
head(lon)
lat <- ncvar_get(ncin,"lat")
nlat...
