In hyfo: Hydrology and Climate Forecasting

Load NetCDF file

Description

Load NetCDF file

Usage

loadNcdf(filePath, varname, tz = "GMT", ...)

Arguments

filePath	A path pointing to the NetCDF file, version3.
varname	A character representing the variable name, you can use getNcdfVar to get the basic information about the variables and select the target.
tz	A string representing the time zone, default is GMT, if you know what time zone is you can assign it in the argument. If tz = '', current time zone will be taken.
...	Several arguments including Year, month, lon, lat type in ?downscaleNcdf for details.You can load while downscale, and also first load than use downscaleNcdf to downscale.

Examples

# First open the test NETcDF file.
filePath <- system.file("extdata", "tnc.nc", package = "hyfo")

# Then if you don't know the variable name, you can use \code{getNcdfVar} to get variable name
varname <- getNcdfVar(filePath)

nc <- loadNcdf(filePath, varname)

# you can directly add your downscale information to the argument.
nc1 <- loadNcdf(filePath, varname, year = 2006, lon = c(-2, -0.5), lat = c(43.2, 43.7))
nc2 <- loadNcdf(filePath, varname, year = 2005, month = 3:8, lon = c(-2, -0.5), 
lat = c(43.2, 43.7))
