Due to unstable access to #SSMIS data, we are suspending today the distribution of our #SeaIce concentration interim climate data record based on it (OSI-430-a).
We advise all users to switch to our #AMSR2 based climate products.

Here's a closer look at the record low sea ice conditions around #Svalbard. The ice edge is still close to the 85°N line of latitude along the Atlantic front. That's a lot of open water into the Barents Sea region! Data from AMSR2.

Technical data update - Due to the U.S. government shutdown, some climate data visualizations on my website may not be updated as usual. I’ll refresh them as soon as possible. Sorry, and thanks for your patience!

Check out iceberg A23a doing some dancing in the Southern Ocean, probably the last dance. You can find it in the extension of the Antarctic Peninsula.

A AMSR2 GW1 89 Ghz microwave image from ~3 1/2 hrs ago indicates that the mid-level structure of Erin in particular had already gotten quite a bit better then this morning (UTC), with more well defined banding now present east of the LLCC but she got a lot of work still to do.

Technical data update - This morning I went through and modified all of my real-time sea ice graphics to be consistent with the new NSIDC Sea Ice Index v4, which now uses AMSR2 for the year 2025.
The effect of this new product version update on my visualizations is expected to be minor.

Can you spot those two eddies shown above in the AMSR2 animation? They are surprisingly stationary and resist southerly drift.

Yes, very low, below 2010s mean. But 2016 is lower in my AMSR2 data and in the NSIDC index. Hudson Bay is record low for the day but not the total extent.

Not only does this make no sense from a security or financial perspective, the president and some of the other worst people on earth live in Florida. It begs the question: are they even aware of what’s happening, or the potential consequences?

Very recent new AMSR2 GW1 microwave images hot off the press suggest that Erin now possesses a closed inner eyewall, this should help drop her MSLP even further. We won't get a new recon mission into Erin for a few hours to see this in action. #tropicswx

PLEASE NOTE: Data source for sea ice concentration and extent has changed.
Beginning 1 July 2025, the Japanese AMSR2 is replacing the US SSMIS instrument for our sea ice concentration and extent products.
SSMIS and AMSR2 differ by ±0.1 million km² or less with larger differences in summer.

There is a good alternative, Japan's AMSR2, however the legacy cost of converting all the models that depended on SSMIS will be a pain in the ass.

Animation of daily #Arctic sea ice concentration so far this year, which reveals how variability is confined to the outer ice edge during winter. It is particularly impacted by changes in weather conditions, such as through storm-driven wind and waves.

Tropical #Storm #Garance has been responding nicely to the decrease in shear overnight. Recent AMSR2 overpass showed a well developed core, surrounded by somewhat concentric banding. Could be at or near the stage of "Intense Tropical Cyclone" when it reaches Réunion. Prepare accordingly! #tropicswx

Shear is still clearly a factor with Dikeledi, as the cyclone is failing to build and maintain a fully symmetrical CDO and clearly defined eye-feature on EIR On the other hand a recently obtained 89 Ghz AMSR2 images shows clear progress in terms of its internal structure #tropicswx

You should they're good!
Recommend any of them really - Zero Mission, AMSR2 (a top tier fan remake - honestly the dogs bollocks), Super, Fusion, or Dread - pretty good experience.
Don't recommend the OG NES game - it's very aged.

New AMSR2 GW1 Microwave color composite images of Hurricane Helene once again show the fully fortified inner core with a nearly full pink ring around the centre. This and the pressure dropping considerably now, down to 952 mbar XTRAP does not bode well.

At a remarkably late date, Hudson Bay is now (almost!) covered in #SeaIce:

Amongst the other peripheral seas, extent in the Sea of Okhotsk is also currently lowest for the date in the #AMSR2 record.
Baffin Bay and #JAXA pan #Arctic extent are both 2nd lowest.

AMSR2 89 Ghz image from about 4 and a half hours ago, shows the vertical tilt of Erin quite well. The deep convection (in red), which correlates with the mid-level troughing/circulation is clearly offset to the southwest relative to the low-level cloud lines in cyan (color?).

Recent AMSR2 GW1 Microwave images caught Typhoon Krathon mid eyewall replacement cycle. Doesn't seem like the fastest cycle but seems to get along relatively smoothly. Eyewall(s) is also closed now. Tho there is another weaker concentric band present for good measure
