In NCAR/rwrfhydro: R tools for the WRF Hydro Model

Description Usage Arguments Details Value See Also Examples

ReadAmerifluxNCOldFormat reads Ameriflux data table (Level 2 standardized NetCDF file) and creates a dataframe. OLDER FORMAT ONLY - NO LONGER SUPPORTED.

1 2	ReadAmerifluxNCOldFormat(pathFluxData, timeZone = NULL, utcOffset = NULL)

`pathFluxData`	The full pathname to the flux time series NetCDF file as downloaded from an Ameriflux data server (OLD FORMAT).
`timeZone`	The time zone for the flux site. Time zone name must be R-friendly for your current OS. See: http://stat.ethz.ch/R-manual/R-devel/library/base/html/timezones.html. Provide this OR a UTC offset. Note that Ameriflux data is (allegedly!) in local time without daylight savings.
`utcOffset`	The UTC offset for the flux site's local time. These should be in positive or negative hours (e.g., -7 for "America/Denver" with no DST shift). These values will supercede any provided time zones. See tzLookup for a list of time zone UTC offsets.

ReadAmerifluxNCOldFormat reads an Ameriflux Level 2 standardized NetCDF file and outputs a dataframe with consistent date and data columns for use with other rwrfhydro tools. OLDER FORMAT ONLY - NO LONGER SUPPORTED. Please use ReadAmeriflux for the latest BASE format support.

A dataframe containing the Ameriflux data.
