Global Performance of #RemoteSensing Based and Reanalysis-Driven Models to Estimate Open Water Evaporation
--
https://doi.org/10.1029/2025WR042363
--
“ABSTRACT: Evaporation plays an essential role in the water cycle, influencing local and regional climates while directly impacting water availability in lakes. However, directly measuring evaporation over water bodies remains challenging due to the high costs of installing and maintaining the required in situ instrumentation. Although several remote sensing algorithms have been providing evaporation estimates, the lack of a global validation hinders our understanding of their relative uncertainties and performances across different regions. Here, [they] analyze[d] the performance of a suite of models that leverage satellite data and meteorological reanalysis to estimate evaporation over lakes worldwide. [They] compare[d] three remote sensing-based models, one reanalysis-driven model and one ensemble approach, using in situ observations from 27 lakes representing a diverse range of geographic and climatic regions. [Their] results demonstrate that, overall, the ensemble outperformed any individual model in terms of accuracy, with a RMSE and a bias of 1.3 and 0.3 mm/day, respectively. These findings highlight the benefits of using an ensemble approach to estimate open water evaporation with satellite-based models at the global scale, leveraging the unique strengths of each model. For the individual models, differences in the representation of heat storage changes and advection effects led to lower values of RMSE and bias, depending on the location and depth of the lakes. This study sets the path for future improvement of open water evaporation algorithms globally, while remote sensing techniques are proven satisfactory to monitoring of water loss in lakes globally, an essential step toward effective large-scale water resources management.
PLAIN LANGUAGE SUMMARY: Water loss through evaporation in lakes and reservoirs directly affects water availability, which highlights the need to monitor these losses. However, measuring evaporation in situ is challenging and expensive. An alternative is to estimate evaporation using remote-sensing models and compare these estimates with in-situ data to verify their accuracy. Here, [they] evaluated four models and their ensemble (the models' mean value) using measurements from 27 lakes and reservoirs worldwide. [They] found that the ensemble presented higher accuracy and consistency than any individual model because it benefits from the strengths of each model. This approach can guide future improvements in estimating open-water evaporation, which is essential for large-scale water-resource management…”

Mapping Sleeping Bees within Their Nest: Spatial and Temporal Analysis of Worker Honey Bee Sleep

H/T Dimitrios A. Karras
“Bees are not only very important for all ecosystems... They are very cute too....
However, bee societies are very complex and different sleep patterns exist for the other kinds of bees in the hierarchy..
In general, bees actually sleep, and many species spend around 5-8 hours resting each day, usually at night when they're not foraging.
Some solitary bees have been photographed sleeping inside flowers, where they cling onto the petals or stamens with their tiny legs and sometimes even their jaws.
One of the cutest parts is that tired bees can look almost like they've fallen asleep at work, curled up inside a flower with pollen still covering their bodies…”

“Patterns of behavior within societies have long been visualized and interpreted using maps. Mapping the occurrence of sleep across individuals within a society could offer clues as to functional aspects of sleep. In spite of this, a detailed spatial analysis of sleep has never been conducted on an invertebrate society. [The authors] introduce the concept of mapping sleep across an insect society, and provide an empirical example, mapping sleep patterns within colonies of European honey bees (Apis mellifera L.). Honey bees face variables such as temperature and position of resources within their colony's nest that may impact their sleep. [They] mapped sleep behavior and temperature of worker bees and produced maps of their nest's comb contents as the colony grew and contents changed. By following marked bees, [they] discovered that individuals slept in many locations, but bees of different worker castes slept in different areas of the nest relative to position of the brood and surrounding temperature. Older worker bees generally slept outside cells, closer to the perimeter of the nest, in colder regions, and away from uncapped brood. Younger worker bees generally slept inside cells and closer to the center of the nest, and spent more time asleep than awake when surrounded by uncapped brood. The average surface temperature of sleeping foragers was lower than the surface temperature of their surroundings, offering a possible indicator of sleep for this caste. [They] propose mechanisms that could generate caste-dependent sleep patterns and discuss functional significance of these patterns…”

"Arénas is a contemporary reimagining of #NorthAfrican #Jewish #music, where traditional #Moroccan textures meet electronics, horns, and sampling.
Shaped by migration, memory, and the energy of the #diaspora, the #album draws on the #artistic worlds of #NetaElkayam and #AmitHaiCohen, alongside influences from #NewOrleans. Across seven extended tracks, Arénas unfolds as an immersive, trance-like listening experience.
Echoing her grandmother’s birthplace in #Tinghir, #Morocco #Elkayam developed an intimate dialogue with her ancestral memory, writing #lyrics through cyclic structures and repetition, and choosing her mother tongue—#MoroccanArabic—as the language of her #art. In close collaboration with #musical #producer Amit Hai Cohen, the #music was co-written and composed, taking shape through a blend of electronic and acoustic #instrumentation. Both trace their family roots to #Amazigh villages in Morocco..."

Hey there, I am Prathamesh Deshmukh, a PhD scholar at UGC-DAE CSR, Mumbai, working in condensed matter physics. My research focuses on magnetoelectric coupling in multiferroic composites and their dielectric, magnetic, and neutron diffraction studies.
Beyond synthesis, I specialise in scientific instrumentation. I designed the Advanced Transport Measurement System (ATMS), a low-cost cryogenic setup for precision transport measurements, and developed PICA, an open-source Python suite for lab automation.
I will be completing my PhD this year and am seeking postdoctoral research opportunities that would leverage my expertise in experimental physics, scientific instrumentation, and software development.

Любая IDE от JetBrains бесплатно: что на самом деле происходит, когда вы запускаете “безобидный” активатор
После ухода JetBrains из России и введения экспортных ограничений многие разработчики столкнулись с банальной проблемой: IntelliJ IDEA Ultimate формально недоступна, а работать нужно сейчас. В результате в ходу оказались «активаторы» — shell-скрипты, которые обещают решить вопрос лицензии за пару минут. Снаружи всё выглядит просто: скачал, запустил, IDE работает. Внутри — Java-агент с Instrumentation-доступом, модификация сетевого стека и вмешательство в криптографические примитивы стандартной библиотеки Java. При этом исполняемый код скачивается с внешнего сервера без подписей и проверок, а установка сопровождается правками системного окружения и использованием sudo. В статье я разбираю один из популярных активаторов на уровне реализации: от .sh-скрипта до трансформаций байткода и подмены BigInteger#oddModPow() . Без эмоций и морализаторства — только факты, архитектура и последствия для безопасности, стабильности и юридических рисков.

Have You Ever Wondered What A New Concrete Stilling Well [stream gauge] Looked Like?
--
H/T Roy Socolow, USGS
"While doing research on the USGS stream gaging program for a local presentation, [he] found this beautiful image of a classic stilling well from the Kentucky archives. Intakes and valve stems in perfect condition, hand pump and flush tank ready to fill, no kerosene or funky well water smell, and the clock weights on the Stevens recorder have plenty of travel room. Makes them] think of the good old days climbing down well ladders to “muck out” wells. Many of these “tanks” of instrument shelters still exist with either working intakes or as converted bubble gages. Many others have been decommissioned due to safety issues (falling or confined space hazards). Thanks to the men of the #CCC and #WPA..."

Off-the-shelf smartphone cameras can do hyperspectral imaging. An ordinary smartphone can be a pocket spectrometer.
You need a smartphone that support RAW (DNG) image capture option or using with third-party applications. You also need a special color reference chart printed on a card.
Computational Photography Spectrometry (CPS) software can then extract 1.6 nm spectral resolution comparable to that of a scientific-grade spectrometer. (patent pending).
“From an algorithmic standpoint, to the best of our knowledge, our paper presents the first computational spectrometry method with 1.5-nm spectral resolution using a photograph of an arbitrary sample without relying on specific training data or predetermined algorithms,”
