๐จ๐ฆ 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.

Let's look up the obvious, planes with an owner of "Edmonton"
There are 4 plane owners with that word in their name:
โฃ Edmonton Soaring Club โ
โฃ Edmonton Flying Club โ
โฃ City Of Edmonton โ
โฃ Edmonton Regional Helicopters Inc. โ

Re-do the search using the correct owner:
The City of Edmonton own four Canadian-registered aircraft:
โฃ C-FEPS Eurocopter EC120B
โฃ C-FEPU Aerospatiale AS350 B3
โฃ C-GEPS Aerospatiale AS350 B3
โฃ C-GMXM Cessna 182Q โ

This is a great tell that comes up frequently. ๐
When watching for any kind of arms shipments, pay close attention to whose airspace is used.

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.
๐บ๐ธ Unknown aircraft using an identifier in the American-allocated ICAO range over #Iraq ๐ฎ๐ถ 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 ๐ค
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. ๐

[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/dโฆ
journals.ametsoc.org/jcli/article/dโฆ
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:
modes.cen.uni-hamburg.de/modes-software
modes.cen.uni-hamburg.de/modes-software
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.
