GrADS is up and running. Until my Raspberry Pi can do the job I’ve dedicated another tiny computer, a Pipo X7S. The X7S is a totally silent, fanless Windows computer. It’s basically a Windows tablet without the screen or touchy stuff.
Over the past few days I’ve spent at least 20 hours pecking away at this keyboard, playing. I’m not ashamed to say that. The best way to learn is by playing.
GrADS is a complex program. To use it I am learning its language and syntax. Spelling and grammar count in programming!
The two maps above were produced at home using this free software and data. They are the very beginning of what can be done. I’m a neophyte.
