WeatherBoard (앞뒤날씨)

Weather now, ahead, and behind - on one screen.

Important: Korea only

This program uses data from the Korea Meteorological Administration (KMA) and Korean air quality stations (AirKorea), so it works for locations in South Korea only. The program's screen is currently in Korean. If you do not live in or travel to Korea, it will not be useful to you. The full guide is available on the Korean page.

Overview

WeatherBoard ("앞뒤날씨" in Korean, meaning "front and back weather") shows the current weather, today's hourly weather, the next 7 days, and the past 7 days, together with fine dust (PM2.5/PM10) and ozone levels, on a single Windows screen.

How to use

1. Search for your location at the top left and press [Save].
2. Left-click a saved location button to select it, right-click to delete it.
3. Weather is not refreshed automatically. It updates when you start the program, press [Refresh], or change the location.

Keyboard shortcuts

Main screen	F1 = Help, F2 = Location search, F3 = Date search, F4 = Settings, F5 = Refresh, Ctrl+S = Save current location, Home / End = Jump to top / bottom

Optional: your own API key (faster)

By default the program fetches data through the author's data server, which may be slower, and waits 10 seconds if you refresh more than 5 times a minute. If you use your own key from the Korean Public Data Portal (data.go.kr), data is fetched directly, which is relatively faster with no refresh waiting. Setting it up requires a Korean-language portal account. See the Korean page for step-by-step instructions.

Required services: KMA Short-term Forecast, KMA Mid-term Forecast, KMA ASOS Hourly Data, AirKorea Air Pollution Information, and AirKorea Measuring Station Information. In the program, open Settings, choose "Personal API", and paste your key.
