If you don't have a WOW ID and Key, press "Register at
WeatherObservationsWebsite" to open a web browser, then sign up.
Follow instructions on the screen and log in to the site
Once you are logged in you will need to create a new WOW site. "Sites"
are the means by which WOW organizes weather data you contribute.
Basically, WOW builds a personal web site for your weather station.
Associated with the web site are two items you will need to allow
uploading of data:
Site ID: This is an arbitrary number that is used to distinguish your site
from another. This number appears (in brackets) next to or underneath the
name of your site on the site information page, for example:
6a571450-df53-e611-9401-0003ff5987fd
Authentication Key: This is a 6-digit number that is used to ensure data
is coming from you and not another user.
Begin setting up a new site by clicking "Enter a Site":
You will be presented with a form where you detail your station's location
and a bunch of other settings related to how you wish the site to operate.
After you complete the setup, you should see:
