himawari-history

Download all Himawari 8 images in a date range.

Install

Warning: requires ⚡ magick ⚡

If you have homebrew installed, you can use that to quickly install graphicsmagick. The rest of the program can be easily installed with npm.

brew install graphicsmagick
npm install himawari-history

If you want to use the video scripts in examples, you'll also need ffmpeg, which can also be installed with homebrew.

brew ffmpeg

Usage

Here's an example showing all options:

var hh = require('himawari-history')
var moment = require('moment')
var path = require('path')

hh({
  start: new Date(moment().subtract(1, 'days').format()),
  end: new Date(),
  interval: 10,
  outdir: path.join(__dirname, 'images'),
  debug: false,
  concurrency: 10,
  zoom: 1,
  infrared: false,
  parallel: false,
  onFileSuccess: function (outfile) {
    console.log(`✅  ${outfile}`)
  }
}, function () {
  console.log('✅  all done')
})

Here's how I downloaded all Himawari 8 images at the base zoom level (1d). This is kind of intense, not recommended for your first spin.

var hh = require('himawari-history')

// Site states:
// "Himawari-8 started operation at 02 UTC on 7 July 2015."
// http://www.data.jma.go.jp/mscweb/en/himawari89/
// All I see is 404s until this date:
var THE_BEGINNING = new Date('Tue, 07 Jul 2015 9:00:00 GMT')

hh({
  debug: true,
  start: THE_BEGINNING,
  concurrency: 20,
  onFileSuccess: function (outfile) {
    console.log(`✅  ${outfile}`)
  }
}, function () {
  console.log('✅  all done')
})

The examples directory has all the scripts I'm working with, including video.js for visible light and video-infrared.js for infrared. The video scripts require images downloaded from the other scripts. This is very thrown together and experimental. Please let me know if you're interested in taking it further!
