Description: Aids in identifying the Koeppen-Geiger (KG) climatic zone for a given location. The Koeppen-Geiger climate zones were first published in 1884, as a system to classify regions of the earth by their relative heat and humidity through the year, for the benefit of human health, plant and agriculture and other human activity [1]. This climate zone classification system, applicable to all of the earths surface, has continued to be developed by scientists up to the present day. Recently one of use (FZ) has published updated, higher accuracy KG climate zone definitions [2]. In this package we use these updated high-resolution maps as the data source [3]. We provide functions that return the KG climate zone for a given longitude and lattitude, or for a given United States zip code. In addition the CZUncertainty() function will check climate zones nearby to check if the given location is near a climate zone boundary. In addition an interactive shiny app is provided to define the KG climate zone for a given longitude and lattitude, or United States zip code. Digital data, as well as animated maps, showing the shift of the climate zones are provided on the following website http://koeppen-geiger.vu-wien.ac.at.

CZUncertainty

Description

This function will return the uncertainty associated with the predicted climate zone along with other potential climate zones.

Usage

CZUncertainty(data)

Arguments

data

The co-ordinates for the location you are trying to predict the climate zone of.

Value

The uncertainty associated with the located climate zone along with other potential climate zones.

Examples

data<- data.frame(Site = c("GC","UFS","NEG"),
  Longitude = c(-15.42,10.98,34.78),
  Latitude = c(27.82,47.42,30.86))
data <- data.frame(data,
  rndCoord.lon = RoundCoordinates(data$Longitude),
  rndCoord.lat = RoundCoordinates(data$Latitude))
data <- data.frame(data,ClimateZ=LookupCZ(data))
data <- data.frame(data, CZUncertainty(data))

LookupCZ

Description

This function will return the climate zone for the co-ordinates provided.

Usage

LookupCZ(data, res = "course", rc = FALSE)

Arguments

data

The co-ordinates for the location you are trying to predict the climate zone of (format is three column dataframe, first column site IDs, second column longitude values, third column latitude values).

res

Specify the resolution as a string - 'course' for lower resolution (default, 0.5 degrees), 'fine' for higher resolution (100s).

rc

Specify whether to generate the rounded coordinate columns in the input dataframe, default is FALSE.

Value

The climate zone for the co-ordinates provided.

Examples

data <- data.frame(Site = c("GC","UFS","NEG"),
  Longitude = c(-15.42,10.98,34.78),
  Latitude = c(27.82,47.42,30.86))
data <- data.frame(data,
  rndCoord.lon = RoundCoordinates(data$Longitude),
  rndCoord.lat = RoundCoordinates(data$Latitude))
data <- data.frame(data,ClimateZ=LookupCZ(data))

RoundCoordinates

Description

This function will round the inputed value to a co-ordinate present in the KG Climate Zone look up table.

Usage

RoundCoordinates(number, res = "course", latlong = "lat")

Arguments

number

The value to round

res

Specify the resolution as a string - 'course' for lower resolution (default, 0.5 degrees), 'fine' for higher resolution (100s).

latlong

Whether the number is a latitude value ('lat', default), or longitude value ('lon') (this parameter is only used if res='fine').

Value

The inputed number, rounded to a value ending in either .25 or .75 (course), or to nearest 'fine' (100s) resolution grid point.

Examples

RoundCoordinates(10.98)
RoundCoordinates(10.98,res='fine',latlong='lon')

RunExample

Description

This function will run the shiny app found in this package.

Usage

RunExample()

Value

launches the shiny app created for the package.

Examples

## Not run: 
kgc::RunExample()

## End(Not run)

TranslateZipCode

Description

This function will return the data frame with the longitude and latitude of the zip codes

Usage

TranslateZipCode(number)

Arguments

number

A dataframe that contains zip codes in a column labeled 'zip'

Value

The original data frame, with two additional columns for the corresponding latitude and longitude

Examples

example <- data.frame("zip" = c(44106,638, 1106))
TranslateZipCode(example)

Arguments

latlong
