“This paper summarizes new achievements in developing and distributing the Global Landsat Level-3 Evapotranspiration (ET) product. It is freely available through the USGS EROS Science Processing Architecture (ESPA) platform (2nd link above). 🛰️ …
Since the product launch in June 2020, there have been over 1.2 million Landsat-based ET orders around the world. This indicates increasing awareness and application of the ET data to help understand and manage the relationships among food, energy, and water resources. 🌽💧 …
It features the ESPA workflow and evaluation of the upgraded SSEBop model using a variety of observational datasets and hydrologic regions, and examination against OpenET SSEBop platform implementation (3rd link above.)…”

H/T @Guillaume Wright | Executive Editor, PLOS
“💧 With drought [and high temperatures] gripping many areas of the world right now... [the H/T] wanted to highlight a new paper in PLOS Water this week with a very timely focus on hydroclimatic stresses and what can be done to mitigate this through water management practices when it comes to agriculture.
[The authors] investigate[d] adaptive water management practices in California’s Santa Clara Valley via remote sensing and machine learning techniques. They [found] good evidence for use of customized agricultural water-management plans for irrigation monitoring, conservation planning, and adaptive water management in groundwater-dependent regions such as is found in California…”

[Flash floods? not TOO hard to conceptualise.
Flash drought? harder to 'get my head around', but H/T / presenter does an excellent job!]
"Not all droughts are the same. In some cases, drought rapidly intensifies at subseasonal to seasonal scales with significant impacts to agriculture and water resources along with the increased propensity for heatwaves and wildfires. Like all droughts, flash drought begins with a precipitation deficit. However, both evaporative demand and soil moisture are critical flash drought variables, and identifying and monitoring the desiccation of the terrestrial surface is key for determining flash drought development and associated impacts. While recent advances in knowledge and monitoring of flash drought have occurred, fundamental questions remain in the state of the science. What are the overall mechanistic relationships between atmospheric demand, evaporative stress, terrestrial desiccation, and precipitation that drive the progression of flash drought? Do regional characteristics of the environment impact the evolution of flash drought? What are the scales of predictability for flash drought? Finally, how will flash drought frequency and intensity evolve in a changing climate system"

"Flash drought intensifies rapidly due to changes in precipitation, temperature, wind, and radiation. These changes in the weather increase evapotranspiration and lower soil moisture. Flash droughts can cause extensive damage to agriculture, economies, and ecosystems if they are not predicted and discovered early..."

What the heck is “#CornSweat” and is it making the Midwest more dangerous?
It’s pretty much just as gross as it sounds.
"In one 2020 study, researchers from the Harvard-Smithsonian Center for Astrophysics analyzed a past summer heat wave in the Midwest and found that cropland — most of which comprised corn in this part of the country — can increase moisture in the air above it by up to 40 percent."
by Benji Jones
Aug 29, 2024"Ah, yes, late August in the Midwest: a time for popsicles by the lake, a trip to the county fair, and, of course, extreme humidity made more miserable by … corn sweat.
"Corn sweat. It’s a thing! And people are talking about it.
The term refers to the moisture released by fields of corn during hot and sunny weather. Like all other plants, corn transpires — meaning, it sucks up water from the ground and expels it into the air as a way to stay cool and distribute nutrients. Moisture also enters the air when water in the soil evaporates. Together with transpiration, this process is called #evapotranspiration.
"So, where you find loads of plants packed tightly into one place, whether the Amazon rainforest or #Iowa, humidity can skyrocket during hot and especially sunny periods, making the air feel oppressive.
"That’s what happened this week: A late-summer #heatwave brought record and near-record temperatures to parts of the Midwest where there also happen to be vast fields of corn. With plenty of sunlight and temperatures in the high 90s, it was enough to make corn sweat, producing extremely uncomfortable weather.
"It’s not that corn sweats more than other plants — an acre releases less moisture on average than, say, a large oak tree — but the Midwest has a lot of corn in late August. In Iowa, for example, more than two-thirds of the area is farmland, and corn is the top crop (followed by #soybeans, which, by the way, also sweat)."
[...]
"Again, it’s not just crops across the #Midwest that release moisture, increase humidity, and make summers feel disgusting (I know firsthand; I grew up in Iowa). The millions of acres of #prairie that industrial farmland replaced — mostly to feed livestock and make ethanol — would have also produced loads of moisture, Basso said.
"But there are some key differences between native #ecosystems and #IndustrialFarmland, he added. '#NativePrairies are diverse ecosystems with a variety of plant species, each with different root depths and water needs, helping to create a balanced moisture cycle,' he told me. 'In contrast, corn and #soy #monocultures are uniform and can draw water from the soil more quickly.'"
