Query nycflights13-Like Weather Data

Description

This function generates a dataframe similar to the weather dataset from nycflights13 for any US airports and time frame. Please note that, even with a strong internet connection, this function may take several minutes to download relevant data.

Usage

get_weather(station, year, month = 1:12, dir = NULL)

Arguments

station	A character vector giving the origin US airports of interest (as the FAA LID airport code).
year	A numeric giving the year of interest. This argument is currently not vectorized, as dataset sizes for single years are significantly large. Information for the most recent year is usually available by February or March in the following year.
month	A numeric giving the month(s) of interest.
dir	An optional character string giving the directory to save datasets in. By default, datasets will not be saved to file.

origin

Weather station. Named origin to facilitate merging with flights data

year, month, day, hour

Time of recording, UTC

temp, dewp

Temperature and dewpoint in F

humid
