write.help | R Documentation |
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.
write.help(file, dat, var = "", name = "", region, lat, visual.help = FALSE, metric = TRUE)
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 |
|
var |
variable to be exported; must be one of |
name |
|
region |
|
lat |
|
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 MJ/(m^2*day) or °F, in./day and langleys/day) |
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
