R: Write climate data in the format used by the HELP model

write.help {seas}

R Documentation

Write climate data in the format used by the HELP model

Description

Write climate data in the format used by the Hydrological Evaluation of Landfill Performance (HELP) model. This exports the data using two slightly different variants of HELP: the DOS versions (3.07 to 3.80D) and for Visual HELP.

Usage

write.help(file, dat, var = "", name = "", region, lat,
           visual.help = FALSE, metric = TRUE)

Arguments

`file`	name of output file; [DOS] HELP uses extensions ‘.D4’, ‘.D7’, and ‘*.D13’ for daily precipitation, temperature and solar radiation, respectively; Visual HELP uses the file names ‘_weather1.dat’, ‘_weather2.dat’ and ‘_weather3.dat’ for the same series of variables
`dat`	`data.frame` of climate data
`var`	variable to be exported; must be one of `"precip"`, `"t_mean"` or `"solar"`
`name`	`character`; location name
`region`	`character`; region
`lat`	`numeric`; location latitude in decimal degrees
`visual.help`	logical formats output for Visual HELP; else formated for the DOS HELP versions (default)
`metric`	logical if using metric units (this only sets a flag, please ensure the data are in either °C, mm/day and `\mbox{MJ}/(\mbox{m}^2 \cdot \mbox{day})` or °F, in./day and langleys/day)

Details

This utility function is experimental and has not been extensively tested; please report any errors to me.

HELP requires continuous data; no missing values are allowed.

Data imported from SDSM use a 365-day calendar, and can be approximated using conv365toGregorian.
