On my mother’s birthday I do things she'd have enjoyed. It was a golden autumn day perfect for interisland ferry knitting. The sky was magnificent, and my Dignity Cap design sample is ready for crown decreases. Happy birthday, Mama.

Looking across the Friday Harbor ferry landing toward Brown Island under an autumn blue sky full of puffy clouds. Grid of spectacular clouds in the deep blue autumn sky above San Juan Islands interisland ferry M/V Tillikum. A hat-in-progress, worked in three-strand helical knitting in robin's egg blue and natural white with double pointed needles (DPNs), ready for crown decreases. Grid of photos aboard WSF interisland ferry M/V Tillikum: view of a passing island from passenger deck, the nearly empty passenger deck, the ferry's wake with islands in the distance, and a view of Friday Harbor through an observation area.

7/31 we honored terminal attendants – Carol Stearns & Frank “Bill” Fletcher – for 50 years at WSF. We temporarily named #Kaleetan on Seattle/Bremerton route the M/V Carol Stearns & #Kennewick on Port Townsend/Coupeville run the M/V Frank Fletcher. Thank you Carol and Frank!

This sucks, and also, proofreading is a lot art. One only has to read this aloud once to realize it.
While the Department of Defense did successfully launched another weather satellite known as the Weather System Follow-on Microwave (WSF-M) in April 2024, that data isn't currently available to forecasters and it's not clear if or when data access will be permitted.

Navy to stop sharing satellite weather data with NOAA
While Defense Meteorological Satellite Program data will no longer be provided to NOAA, the agency has not lost all access to global weather imaging.

A major setback came with the loss of satellite microwave data from the U.S. military’s DMSP system, which NOAA relied on for nighttime storm observations. Its replacement, WSF‑M, is delayed.

The whole thing raises more questions than it answers. The satellites work. Why not keep the data flowing to the scientists who use them to forecast some of the deadliest storms on earth? And no one WSF-M satellite doesn't solve this and right now we don't have access to that data regardless.

Did you know, if a WSF boat has a gold stripe on the funnel, it has been in service half a century?

The more you know.

Thanks to Scott for answering about whether data from the military's WSF-M satellite microwave will be available to civilians. It sounds like there's some plans, which is good - but from the little I can find on the web about the WSF-M instrument it does not seem like a real replacement for SSMIS.

My sources here at CIMSS tell me that it should be soon, since cal/val is now complete and NOAA signed off on data release recently.

This means weather centers could very well use #SatDump to still get the data they need for hurricane analysis, right now, in real time, with simple equipment. WSF-M also coming.

It was recently announced that DMSP SSMIS data wouldn't be available - so with @lego11.bsky.social we decided to add support in SatDump :-)

Still lacking more samples (IQ) to do projections, but we can already process SSMIS data. Calibration is likely possible as well.

The service is crafting a plan to replace its legacy weather capability, and WSF-M and its companion EWS program are a bridge to that architecture.

examples for eight cities

demonstrating the amount of spatial detail present (but scarcely visible) in the global map.

“height” in the pseudo-3D maps
indicates building mass per 90 m pixel
Maps of material stocks in buildings in eight selected cities (one per region) around the world. The squares delimiting the 3D outtakes measure 5 × 5 km. Due to the projection used, the size of pixels differs between cities: At the equator, they measure 90 × 90 m, but their exact size varies according to the location of each city in relation to the equator. Data behind this map are available at full spatial and temporal resolution as DLR data product (“World Settlement Footprint (WSF) 3D Material Stock - Material Stock- Global, 90m”) at https://doi.org/10.15489/h80jhtr41x48 (DOI: 10.15489/h80jhtr41x48).
