The Meteostat Julia library provides a simple API for accessing open weather and climate data. The historical observations and statistics are collected by Meteostat from different public interfaces, most of which are governmental.
Among the data sources are national weather services like the National Oceanic and Atmospheric Administration (NOAA) and Germany's national meteorological service (DWD).
This project is not affiliated to the Meteostat organisation. Do consider donating to support the open source project.
import Pkg
Pkg.add("Meteostat")Let's plot 2018 temperature data for Vancouver, BC:
# Import Meteostat library and dependencies
using Meteostat:Point, fetch_data
using Dates
using AlgebraOfGraphics, CairoMakie
# Set time period
start_date = Date(2018, 1, 1)
end_date = Date(2018, 12, 31)
# Create Point for Vancouver, BC
location = Point(49.2497, -123.1193, 70.)
# Get daily data for 2018
weather_data = fetch_data(location, Dates.Day, start_date, end_date)
# Plot line chart including average, minimum and maximum temperature
fig = (
data(weather_data)
* mapping(:time, [:tavg, :tmin, :tmax], color=dims(1) => renamer(["avg", "min", "max"]) => "Temperatures ")
* visual(Lines)
)
draw(fig;
