National Park weather data
A collection of Bash shell scripts to scrape/collect weather data, web camera images, radar imagery, satellite views, etc. to display current weather information, time-lapse animations, and create an archive of weather observations.
The scripts are used on Ubuntu 14 and requite a few packages to be installed on the server:
Web pages use Leaflet JS library to display current radar map overlays.
The primary script is
make.sh which runs the other scripts in the proper order. You'll need to create a
crontab to keep the weather data current.
# crontab example # The source imagery and observations are downloaded every 30 minutes to conserve server storage. */30 * * * * /bin/sh/ /path/to/weather/directory/make.sh
The scripts have a few goals:
- Pull down weather imagery and data with
- Process the imagery with
montageto make thumbnails, add date stamps, and optimize for web viewing
- Scrape text data with
pcregrepto format and serve on a web page.
- Create animated gifs for national park webcams and archive the imagery with a unique URL every day.
- Create a raster tileset for the latest doppler radar for the Daniel Boone National Forest and serve on a slippy map.

The source data primarily comes from the National Weather Service and various NOAA agencies. The exact URLs are shown in the
get-img.sh scripts. Also using/exploring the Dark Sky API for hyperlocal data. The Weather Underground API for RSS feeds has also been used in the past. Imagery for the GOES-16 satellite is downloaded from UW-Madison Department of Atmospheric and Oceanic Sciences, https://www.aos.wisc.edu/
outrageGIS mapping makes trails maps to carry into the backcountry. Knowing the weather is pretty helpful.
The first use of the scripts was in June, 2007.
