This is where all the weather apps and websites get their data. They just package it up and add advertising or charge you. You can do this yourself with a computer by getting the data from NOAA and the easy-to-use Panoply software from NASA for free.

* You don't have to use your email address, but it is standard courtesy in anonymous ftp to use your email address as a password so that they can log where users are coming from. For instance, if you are a teacher or student, use your school email address so they can log you as an education user. This is how we discover needs and allocate funding.
