“Winter roads are essential transportation links for many remote northern communities, but their safety and reliability depend strongly on snow conditions and ice growth. In this study [link above], [the authors] evaluated a fully polarimetric, dual-frequency Ku- and Ka-band radar approach for retrieving snow depth across landfast sea ice, lake ice, and tundra.
Using field measurements near Churchill, Manitoba, and Resolute Bay, Nunavut [Canada], [they] found that the approach produced snow-depth retrieval bias and error within 3 cm over landfast ice, with encouraging Ku-band performance over frozen ground as well. [They] also developed an interface-detection approach for lake ice that can retrieve both snow depth and ice thickness - a promising direction for characterizing conditions relevant to winter-road planning and safety…”

“Winter roads are lifelines for remote northern communities. Built over land, lakes, rivers, and sea ice, these travel routes are increasingly vulnerable to warming temperatures and variable precipitation. To ensure safety and adapt to these changes, operators require high-resolution monitoring of snow depth across these diverse surfaces, as natural snow accumulation dictates ice growth rates, route viability and road stability. This study extends our polarimetric radar method, previously demonstrated on pack ice, to landfast sea ice, tundra, and frozen lakes and assesses how well we can retrieve snow depth over these surfaces. Results indicate consistency with earlier sea ice analyses, maintaining a mean snow depth retrieval bias and error within 3 cm over the landfast ice. Promising performance is also found over frozen ground using Ku-band (mean biases less than 6 cm). To address the specific challenge of lake ice, which includes strong returns from the ice/water interface, we present a new interface-detection technique that simultaneously retrieves snow depth and ice thickness. While current validation focuses on undisturbed snow, this approach could provide a path forward for characterizing the cryospheric environment in a way that can directly support the optimization of winter roads…”

Ich stimme dem zu, möchte jedoch noch Folgendes ergänzen: es ist in den letzten Jahren ein sehr starker Fokus auf #CO2 als #Treibhausgas erfolgt.
Bislang lagen fast alle #Klimaprognosen unter der Realität. Könnte es vielleicht sein, dass das #Treibhausgas #Methan noch zu wenig beachtet wird?

Insbesondere durch das Auftauen des #Permafrosts in der #Tundra dürfte das Problem noch schlimmer werden:

"Permafrost soils store vast amounts...

@makesubarugayagain everyone’s complaining about BMW, but having seen both multiple times now, these are the ugliest grilles on any vehicle out there, including the #Tundra the #RAV4 and almost every other #Toyota.

These stand out in a bad way, but for me personally, the #BMWiX and #BMWi4 actually stand out in a good way. They differentiate themselves without being offensive, but it’s JMO.

Saw my first #BMWXM too, and didn’t dislike that either. 🤷‍♂️
