HOMSTART Precipitation Data

Description

This function downloads and compiles the HOMSTART-project data set. The data is downloaded from the Zentralanstalt fuer Meteorologie und Geodynamik (ZAMG, http://www.zamg.ac.at) and funded by the Austrian Climate Research Programme (ACRP) and is free for research purposes.

Usage

homstart_data(dir = NULL, load = TRUE, tdir = NULL)

Arguments

dir	The directory where the homstart.rda file should be stored.
load	Should the homstart data be loaded?
tdir	An optional temporary directory where all downloaded files are processed.

Value

A data frame containing the following variables:

raw	The daily precipitation observations.
cens	Precipitation observations censored at 0.
bin	Factor with levels "yes" or "no" indicating precipitation.
cat	Factor with levels "none", "low", "medium" and "high" indicating the amount of precipitation.
trend	A numeric time trend
month	Month of of the observation.
year	Year of the observation.
day	Day of the year.
lon	The longitude coordinate of the corresponding meteorological station.
lat	The latitude coordinate of the corresponding meteorological station.
id	Factor, meteorological station identifier.
cos1, cos2, sin1, sin2	Transformed time trend for harmonic regression.
weekend	Factor, with levels "yes" and "no" indication if the observation was measured on a weekend.
elevation	Numeric, the elevation of the meteorological station.
