๐Ÿ‡จ๐Ÿ‡ฆ Excellent report by @Breanna_KS about the Edmonton Police Service's "secret" surveillance plane, but it leaves a lot of questions unanswered, like, how didn't I notice that one before?

Let's go over (granted, with hindsight) all the details.

๐Ÿ‘ฎ ๐Ÿ›ฉ๏ธ ๐Ÿ‘‹
Let's look up the obvious, planes with an owner of "Edmonton"

There are 4 plane owners with that word in their name:
โ€ฃ Edmonton Soaring Club โŒ
โ€ฃ Edmonton Flying Club โŒ
โ€ฃ City Of Edmonton โœ…
โ€ฃ Edmonton Regional Helicopters Inc. โŒ
Re-do the search using the correct owner:

The City of Edmonton own four Canadian-registered aircraft:

โ€ฃ C-FEPS Eurocopter EC120B
โ€ฃ C-FEPU Aerospatiale AS350 B3
โ€ฃ C-GEPS Aerospatiale AS350 B3
โ€ฃ C-GMXM Cessna 182Q โœ…

This is a great tell that comes up frequently. ๐Ÿ‘‡

When watching for any kind of arms shipments, pay close attention to whose airspace is used.

๐Ÿ“กโœˆ๏ธ I wrote an article about how aircraft traffic situational awareness can be improved by capturing aircraft transponder signals, using open source-based software defined radio receivers

Let's consider the Islamic Emirate of #Afghanistan's airspace

Here's what I wrote last time about #Iraq, and how to improve aircraft traffic situational awareness over Iraq, by capturing the transponder transmissions the aircraft are broadcasting. #ModeS #ADSB #ADSBexchange

The largest cities in Afghanistan are #Kabul, #Herat, #Mazar_e_Sharif, #Kandahar, and #Jalalabad. If any cities in #Afghanistan were to have telecom infrastructure and internet access, it's those five cities. Image

๐Ÿ‡บ๐Ÿ‡ธ Unknown aircraft using an identifier in the American-allocated ICAO range over #Iraq ๐Ÿ‡ฎ๐Ÿ‡ถ tonight; no idea what it is, all info is blank (incl alt, squawk, etc) and I can't find any historical information about it (other than it was last seen 2020-01-06 & 2020-01-17) #AAD30F ๐Ÿค”
Given the constant buzz of American ISR assets over Iraq, it's probably just one more, but the rest of them are pretty loud and proud about their identity. Already L3, Textron, and other contractors can be noticed operating over Iraq all night long, every night.

There is nothing secret about the Boeing 747s that are commonly referred to as "Air Force One" (planeS, there are two!), we track them all the time, and the links are available on Twitter for you to follow along too. ๐Ÿ‘‡

[THREAD] Our article (with @NedjeljkaZ from @CENunihh and Khalil Karami) on Atmospheric Subseasonal Variability and Circulation Regimes: Spectra, Trends and Uncertainties is out in @AMSJCLi

journals.ametsoc.org/jcli/article/dโ€ฆ
We decompose 35-year long datasets of the atmospheric circulation in the global reanalyses systems (ERA5 and ERA-Interim of @ECMWF, MERRA of @NASAEarth and JRA-55) into balanced (Rossby) and unbalanced (inertio-gravity) circulation using #MODES:

Most striking: all reanalyses show a reduction of subseasonal variability in Rossby waves with zonal wavenumber k=6-8 and an increase in wavenumbers k=3-5 in Northern Hemisphere summer (June-July-August) over 1980-2014. Similar but smaller signal is found also in other seasons. Relative change of subseaso...
