Le radar de l’ours, Avril 2025

[Storm Thread - Mid WIllamette Valley, Oregon]

So it begins.

We are now seeing a few stormheads between Corvallis and Newport.

Here in the mid-valley, the overcast is just taking us now, nothing impressive in the skies yet, but watching the satellite views, I see crazy amounts of clouds springing up as the front moves in.

You say Jindalee I say JORN you say Over The Horizon

and I wont mention the Over the Ocean stuff either...

#RADAR #Canada #Australia #DEWline #Stealth

The DEW line is very old now, an given the silly billies running ops in the States... (me being dreadfully polite)

Quietly quietly now.

They are upgrading the #software running a #radar I work with. One of the tests is obviously how good the data looks. The new software has higher standard deviations than the old software (#statistics)

And that's it. They are trying to debug it based on just the std dev.

I looked at one of the tracks and there was clearly a time dependent trend.

I keep telling them and telling them that just thinking in terms of "standard deviation" is making them assume gaussian #noise sources.

But if you look at the #data as a *time series*, you will start thinking about the processing and what would be happening at different points in a track and how it might go wrong starting at certain points.

It's a purely software #engineer team--they know about radar (more than I do!), but aren't #system engineers.

It's been going on long enough that I want to say something to someone higher up. But I don't want to adopt another project....

4:30 P.M. #RADAR UPDATE:

A line of #rain #showers has been moving into the #Northland from the south this afternoon.

Northwest Wisconsin, the I-35 corridor, and the Upper Peninsula will see them through early evening.

Some of it will eventually become #freezing rain tonight north of Highway 2.

2HP Kick & pocket radio + Bastl Skis generating the sounds. korg mixer is clock source sent to pachinko & to Trig Divider giving a variety of rhythmic patterns between the two. I can combine triggers with Or widgets (for ex, on 2 and 5). Radio headphone out is too low for eurorack so am using the #behringer #radar as gain.

The nice thing about using a real analog radio (am, Fm, shortwave) is that you never know what you'll get

This guy built a drone with an imaging synthetic aperture radar. DIY on a whole other level. Super interesting read.

Here's that time we were doing work down by the #Detroit Metro #Airport and right behind the ATC #radar tower that is enclosed with a golf ball looking dome.

Le radar de l’ours, Février 2025

https://ours-inculte.fr/radar-fevrier-2025/

So it is shaping up to be an interesting weather day here in the islands. We have a storm blowing through from the South bringing gusty winds, heavy rain, and flooding.

Right now, things are very breezy here in South Maui. The sky is dark and it is raining on and off. No flooding here just yet.

First band of light precipitation now coming onto the South Island. Rain already happening over Campbell River and Courtenay. Likely some snow falling in some lower elevation areas and certainly in the mountains.

First precipitation in nearly a month!

After the past coupla days/nights tis now quite novel to look at the #BoM #radar map & NOT see yet another incoming yellow/orange/red/black monster approaching.

#Iran has deployed a number of advanced NAZIR radars in the north of the country with a range of up to 800 km.

In the picture below the operating range of these radars is specified.

The entire skies of #Azerbaijan, #Armenia, parts of the skies of #Russia and #Turkey are under the surveillance of the #radar.
