Event Notification for Thredds Servers

Periodically some of the Thredds servers run by Unidata get seriously overloaded. One cause is because external users poll the Thredds server to see what has changed. If the polling rate is too high then the performance of the Thredds server can seriously deteriorate.

I am proposing here to mitigate this problem by allowing Thredds servers to generate events that signal changes that might be of interest to users. Then, instead of polling, these users can watch for specific changes events and use that information to update their local databases (or whatever).

MetPy Mondays #6 - Making a Basic Map with Cartopy

One of the most common tasks we do as geoscientists is make maps. Maps are a great way to look at massive amounts of data and synthesize it. In Python, Cartopy is the most current mapping package available and is what we use in all of our MetPy Gallery and Python Gallery examples. In this week’s MetPy Monday, we’ll look at the fundamentals of mapping with Cartopy and create a couple of simple base maps that data can be plotted on.
