11. SECRET LABS AB www.secretlabs.com from SMHI import fixup def process(context, im): return fixup(im) N2 Processing  Scheduling based on product availability and time  Process scripts written in Python  Process scripts have access to extensive code libraries, and user-provided code  Persistent job queue from RadarImage import compose def process(context, im): ims = context.getproducts() return compose(ims) def process(context, im): return im.rotate(45) SMHI RAVE PIL Numerical Python Python Standard Library User-provided libraries Nordrad Support

12. SECRET LABS AB www.secretlabs.com N2 Distribution  Event-driven notification  Client fetches data (pull, not push)  Fetch raw or visualised data  Persistent fetch queue Step 1. Event Step 2. Request Step 3. Data transfer

13. SECRET LABS AB www.secretlabs.com Nordrad 2 Design Goals  Decentralized  Easy to use  Easy to adapt and expand  Secure and reliable

14. SECRET LABS AB www.secretlabs.com N2 Design Goals, cont’d  Decentralized: self-contained nodes, multiple platforms, standard protocols  Easy to use: multiple user interfaces, scripted architecture  Easy to adapt and expand: scripts, plug in your own algorithms  Secure and reliable: simple, battle-hardened design (running PROSAT since 1995)

15. SECRET LABS AB www.secretlabs.com That’s all, folks  Well, almost: - demo (nordrad2-on-a-laptop ;-) - questions? (now or later) Thank you for listening!
