Hurricane Tracking

This week we talk about the NOAA, FEMA, and the SSMIS.

We also discuss Arctic ice, satellite resolution, and automated weather observation stations.

The National Oceanic and Atmospheric Administration, or NOAA, is a US scientific and regulatory agency that tackles an array of environmental, climatic, and weather-related issues, alongside its responsibilities managing oceanic ecosystems.

So it’s in charge of managing fishing protections and making sure endangered species within US waters are taken care of, but it also does scientific exploration—mapping the ocean, for instance—it monitors atmospheric conditions and keeps tabs on the various cycles that influence global and US water, air, and temperature happenings, and it tracks macro- and micro-scale weather events.

That latter responsibility means NOAA (which is the modern iteration of several other agencies, including the US Environmental Science Services Administration and the US Weather Bureau) also manages the US National Weather Service, which is the sub-agency that sends out hazardous weather statements when there are severe storms or tornadoes or other weather-related events of note in a given area, and which also provides weather forecast information that local experts on the ground use to make their own predictions.

Most of what the National Weather Service puts out is in the public domain, which means anyone can access and use it, free of charge. That’s a pretty big deal, because the data they collect and informational products they distribute, including all those hazardous weather statements, are at times life and death, but they’re also a big part of what makes standard local weather services possible in the US—they help the FAA and other agencies do their jobs, and they help everyday people understand how hot or cold it’s going to be, whether to pack and umbrella for the day, and so on.

To accomplish all this, the NOAA and its sub-agencies make use of a bunch of facilities and other tracking resources to collect, aggregate, and interpret all those data points, crunching them and spitting them back out as something intelligible and useful to their many end-users.

They’ve got weather observation stations across the US, many of them automated surface observing stations, which are exactly what they sound like: automated stations that collect data about sky conditions, wind direction and speed, visibility, present weather conditions, temperature, dew point, and so on—most of these are close to airports, as this information is also vital for figuring out if it’s safe to fly, and if so, what accommodations pilots should be making for the weather and visibility and such—but they also collect data from smaller weather stations scattered across the country, around 11,000 of them, many operated by volunteers under the auspices of an effort called the Cooperative Observer Program that was established in 1890, and that’s paired with another volunteer data-collection effort called the Citizen Weather Observer Program.

There are also weather buoys and weather ships lingering across the surface of the ocean and other bodies of water, tracking additional data like sea surface temperature and wave height at various points. And there are weather balloons which collect additional information about happenings further up in the atmosphere, alongside the many satellites in orbit that capture various sorts of data and beam that data down to those who can make use of it.

Again, all of this data is collected and crunched and then turned into intelligible outputs for your local weather forecasters, but also the people who run airlines and fly planes, the folks out on boats and ships, people who are managing government agencies, scientists who are doing long-term research
