import * as gfsScraper from 'gfsscraper';

gfsScraper.downloadStep('./out.grib2', '2018082712', '000', 'all'); // Downloads all parameters and heights for selected step

gfsScraper.downloadStep('./out.grib2', '2018082712', '000', [{
    height: '2maboveground',
    parameter: 'TMP'
}, {
    height: 'surface',
    parameter: 'LAND'
}]);

See example/example.ts

The industry standard for GFS GRIB file downloading is get_gfs.pl. It's quite old, and not a whole lot of people are proficient in perl... Hopefully TypeScript is easier to maintain and improve!

Also, making new things is fun!

• Remove coupling to GFS (make more generic)
• Prettier Logging
• UI For selecting parameters (FUTURE)
