wind.fit: Wind-data fit

Description

wind.fit is used to transform a data.frame obtained from wind.dl. wind.fit applies trigonometry tools to transform U and V vector wind components in wind direction and speed features. It also transforms 0-360 longitude notation obtained from GFS data into -180/180 longitude notation to be used in GIS (Geographic Information Systems) or for R plots. Moreover, it cleans column names obtained from wind.dl, deletes "time" column and sorts the data by latitude.

Usage

wind.fit(X)

Arguments

X

data.frame generated by wind.dl function from "rWind" package.

Value

A data.frame prepared to be plotted by R or to be exported as a CSV file to be used with a GIS software.
