Does anyone know anyone at the NOAA ARL/who has anything to do with the NCEP/NCAR reanalysis data?

It looks like the 1948 and 1949 data have been mislabelled as 2048 and 2049 - noticed when running HYSPLIT trajectory models.

I've sent an email via the general NOAA research office, but not convinced it will get to the right people...

Jupiter in a Lab

The vivid bands of a gas giant like Jupiter come from the planet’s combination of rotation and convection. It’s possible to create the same effect in a lab by rapidly spinning a tank of water around a central ice core. That’s the physical set-up behind this research poster–note the illustration in the lower right corner. The central snapshots show how temperature gradients on the water surface change the faster the tank rotates. At higher rotational speeds, the parabolic water surface gets ever steeper and Jupiter-like temperature bands form. (Image credit: C. David et al.)

Thermal Tides Drive Venusian Winds

Venus is a world of extremes. A full rotation of the world takes 243 Earth days, but winds race around the planet at a speed that makes a Category 5 hurricane look sedate. Just what drives these winds has been an ongoing question for planetary scientists. A recent study suggests that tides are a major contributor to this superrotation.

Unlike Earth’s tides, Venus’s are not gravitational in origin. Instead, Venusian tides are thermal, driven by heating in the sunward side of the atmosphere. This creates a diurnal tide, which cycles once per Venusian day and pumps momentum toward the tops of Venus’s clouds. The new analysis–rooted in both observations and numerical simulation–finds that diurnal tides are the primary driver behind the planet’s incredibly fast winds.

We put together tens of studies on the mass absorption cross section (MAC) of atmospheric #BlackCarbon aerosols. Large uncertainties in MAC values are mostly due to artifacts of the measurement techniques.

Panama’s Missing Pacific Upwelling

Strong seasonal winds blowing from the Atlantic typically push water away from Panama’s Pacific coast, allowing deeper, colder waters to rise up. This upwelling cools reefs and feeds phytoplankton blooms, both of which support the rich marine life found there. But in early 2025, the upwelling didn’t occur.

Normally, coastal ocean temperatures drop to about 19 degrees Celsius during upwelling. Instead, temperatures only reached 23.3 degrees at their coolest. Wind seems to be the missing ingredient: winds from the Atlantic side were short-lived and 74% less frequent than in typical years.

That lack of upwelling is expected to carry consequences to Panama’s economy. About 95% of the country’s fishing catch comes from the Pacific side, so any drop in fish populations will be felt. The open question remains: was the missing upwelling a singular extreme event or a harbinger of a new normal? (Image credit: R. Heuvel; research credit: A. O’Dea et al.; via Eos)

@space_environmentalism @planet4589
Exactly the problem.

We failed to understand that there are risks to evaluate.

Unfortunately, unless we have a global process, Starlink, etc will simply swap launch sites to countries that don't care about safety or ecosystems or sustainable use of scarce orbital space.

Unlike Vegas, what happens "here" doesn't stay "here". And satellite debris seems to disperse to everywhere.

Cloud Convection on Titan

Saturn’s moon Titan is a fascinating mirror to our own planet. It’s the only other planetary body with surface-level liquid lakes and seas, but instead of water, Titan’s are made of frigid ethane and methane. Like Earth, Titan has a weather cycle that includes evaporation, condensation, and rain. And now scientists have made their first observations of clouds convecting in Titan’s northern hemisphere.

Using data from both the Keck Observatory and JWST, the team tracked clouds on Titan rising to higher altitudes, a critical step in the planet’s methane cycle. This translation took place over a period of days, giving scientists modeling the Saturnian moon new insight into the seasonal behaviors of Titan’s atmosphere.

A Sprite From Orbit

A sprite, also known as a red sprite, is an upper-atmospheric electrical discharge sometimes seen from thunderstorms. Unlike lightning, sprites discharge upward from the storm toward the ionosphere. This particular one was captured by an astronaut aboard the International Space Station. That’s a pretty incredible feat because sprites typically only last a millisecond or so. The first one wasn’t photographed until 1989. (Image credit: NASA; via P. Byrne)

On 27th May, the U.S. Federal Communications Commission published "FCC Kickstarts a Proceeding that Could Unlock More than 20,000 Megahertz of Spectrum for High-Speed Internet Delivered from Space". (https://www.fcc.gov/document/fcc-looks-unleash-more-spectrum-satellite-spectrum-abundance) Some of it is a Notice of Proposed Rulemaking and other parts are a Further NPRM. This proceeding has not been released in the Federal Register, so we don't yet know when comments and reply comments are due.

The Commission seeks comment on expanding satellite connectivity across four spectrum bands: 12.7-13.25 GHz, 42.0-42.5 GHz, 51.4-52.4 GHz, and the so-called "W-band" at 92.0-94.0 GHz, 94.1-100 GHz, 102.0-109.5 GHz, and 111.8-114.25 GHz. It covers a number of bands and certainly touches on areas of concern to both #RadioAstronomy and #AtmosphericScience.
