Now let's calculate the standard deviation of forecasts among the ensemble members, and then plot them for the entire globe as well as only North America: png Looking at the above plots, we can see that the uncertainty of temperature forecast in February 2021 is much higher across the northe...
But there's one problem. We have a bunch of strings. We're going to have to do math with this to calculate things such as the broadcast parameters, the netmask, and, ultimately, our IPs. So let's convert our CIDR into an integer. NOTE For a refresher on subnetting and CIDR ...
