loadNcdf function

Load NetCDF file

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.

Returns

A list object from hyfo containing the information to be used in the analysis, or biascorrection.

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))
