Podcasts about Evapotranspiration

I had an optimistic thought about the effects of global warming, and I put it to the test with Dr. Meetpal Kukal.

U of I researcher coins ‘thirstwaves' as new framework emphasizing prolonged, extreme water stressors.

Two Ben-Gurion University M.Sc students, Mr. Kelvin Kiplagat and Ms. Leah  Waweru from Prof. Nurit Agam's course “Hydrometeorology” graduate course present their take on an amazing class assignment: Find a creative way to explain Evapotranspiration, a crucial process for the Earth's water cycle and climate. So, they came to BGU Radio's Sde Boker Campus studio and podcasted their way to a superb grade!

Nicole and Michael dare to record an episode of their famous podcast later in the day than usual, resulting in a exploration into topics like gabapentin for dogs, getting sick at the dentist, what's wrong with the final seasons of your favorite shows, and more.

Managing water resources effectively is crucial, especially in regions facing scarcity and drought. The OpenET platform, developed through collaboration between NASA, the Environmental Defense Fund, and other partners, offers a groundbreaking solution by leveraging satellite data to measure evapotranspiration. In this episode, we hear from Forrest Melton of NASA and Robyn Grimm, formerly of the Environmental Defense Fund, who explain the science behind OpenET and its diverse applications. The episode also features insights from various users across the water sector, including farmers and water managers, who discuss how OpenET is transforming their approach to water use and conservation. From supporting regulatory compliance to optimizing irrigation, OpenET is proving to be a critical tool for ensuring sustainable water management in the face of climate challenges.waterloop is a nonprofit news outlet.

In this episode of Eyes on Earth, we spoke with Mikael Hiestand, a Mendenhall Postdoctoral Fellow. Using algorithms developed at EROS, Mikael is working on near-term drought forecasting. With synthetic Landsat data, he found that predicting evapotranspiration could be used as a means of drought prediction and monitoring. The Mendenhall Fellowship allows people who have just completed their PhD an opportunity to work on research with USGS scientists and prepare for their career.

Pistachios are very salt tolerant, at least compared to most of the other orchard crops that are grown in California. However, this does not make them immune to the effects of salinity. Daniele Zaccaria recently wrapped up a four year study examining the water use of trees under varying levels of soil salinity and found that water use decreases as soil salinity increases. This has major implications for tree health and water use post SGMA.

This is the first in a series of podcasts looking into an important greenhouse production topic, vapor pressure deficit or VPD. Host Bill Calkins talks to guest Dr. Will Healy in an attempt to make some fairly complex information understandable and usable in this conversation about VPD, relative humidity and water loss. They are following up on a print article ran in the January issue of GrowerTalks magazine that walked readers through some definitions related to VPD, as well as why it is an important measurement to use and how it can specifically benefit young plant production. This episode (and the others in the series) goes quite a bit deeper into the topic.   Dr. Healy has more than three decades of experience working with greenhouses of all shapes and sizes and around the world to implement the best strategies for their unique situations. Will retired recently from Ball Horticultural Company but continues to think about ways to improve horticultural production.   In the first podcast of the series, Will and Bill focus on clarifying the importance of VPD and Relative Humidity (RH), as well as explaining the process of Evapotranspiration. The episode sets the stage for upcoming presentations covering when VPD is most critical and ways to manage this integral piece of your greenhouse environment puzzle.   RESOURCES:   VIEW THIS PRESENTATION AS A VIDEO WITH SLIDES: https://youtu.be/MGb8RjLV3U0 Learning Curves & Data Curves, GrowerTalks January 2023 by Bill Calkins (article): https://www.growertalks.com/Article/?articleid=26085 Plant Empowerment (book): https://www.plantempowerment.com/in-practice/the-book/ Tech On Demand—Training Your Team to Water Properly (video): https://youtu.be/SCPPT0IXlLY

How can we measure water when it disappears into thin air? On this episode of What About Water? we're looking at evapotranspiration, or “ET” for short. It's the combination of water evaporating from the soil, combined with the measure of water transpiring through crops' leaves. Accounting for this water loss helps farmers know exactly how much water they should apply across their fields, and new agricultural technologies and satellites are making it much easier.    Jay sits down with California State University at Monterrey Bay Senior Research Scientist –  and former student – A.J. Purdy, whose doctoral thesis looked at the advancement and applications of satellite-derived ET algorithms. We also hear what this looks like in real life, with Brett Baker, a sixth-generation California pear farmer and lawyer. With the ever-present risk of flood on his family's land in the Sacramento-San Joaquin River Delta, Baker explains how OpenET is helping farmers like him and his father take better measurements of consumptive use.  Robyn Grimm, Interim Director of OpenET, tells us how this open-source platform is making big waves. 

Some plants are simply better at making use of their water supply than others. More efficient plants can capture more carbon with less water, which has implications for carbon sequestration and ultimately for climate change modeling. In other words, the more we understand about water use efficiency, the more reliable our climate change models can be. And the only way to measure efficiency at the global scale is from space. On this episode of Eyes on Earth, we hear from a scientist who studied global water use using a sensor called ECOSTRESS, whose data are housed at the USGS EROS Center, in NASA's Land Processes Distributed Active Archive Center (LP DAAC).

If you want to know how much rain fell yesterday, you can catch it and measure it. Water vapor? That's not so easy. Which is a problem if you want to know how quickly that rate is returning to the atmosphere. Water vapor is the single largest part of the water budget, but without space-based observations, it would be all but impossible to measure at wide scale. On this episode of Eyes on Earth, we learn how a sensor called ECOSTRESS helps improve the space-based measurement of evapotranspiration, or ET, which is the combined rate of evaporation from the Earth's surface and transpiration from plants.

Fires can be destructive or healthy for a landscape—often both. Fires have grown larger and more destructive in recent years, though, thanks to human activity, climate change, and a host of other factors. Satellite data helps us to map and monitor fire activity, but the study of post-fire plant life using remote sensing data goes further than fire mapping. On this episode of Eyes on Earth, we hear from Dr. Helen Poulos, who used data from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station, (ECOSTRESS), to study Arizona Pine Oak forest 5-7 years after severe fire. Dr. Poulos and her collaborators at Northern Arizona University and the University of Maine at Farmington learned that post-fire shrublands had surprisingly high rates of water use. ECOSTRESS data are available through NASA's Land Processes Distributed Active Archive Center or LP DAAC, which is located at EROS.

"Das Klima”, der Podcast zur Wissenschaft hinter der Krise. Wir lesen den aktuellen Bericht des Weltklimarats und erklären den aktuellen Stand der Klimaforschung. Kapitel 8 des IPCC-Berichts beschäftigt sich mit dem Wasserkreislauf der Erde. Das klingt erstmal simpel, ist es aber natürlich nicht. Wir haben jede Menge Wasser in allen möglichen Formen und überall. Nachdem wir eine aquatische Bestandsaufnahme gemacht haben und wissen, wo sich das Wasser überall herum treibt, schauen wir zuerst, was dazu führen könnte, dass sich an diesem Kreislauf etwas ändert. Dann untersuchen wir, wie sich der Kreislauf bisher verändert hat und schauen am Schluss, wie er sich in Zukunft verändern wird. Dabei lernen wir nicht nur so schöne Worte wie “Telekonnektion” oder “Evapotranspiration” sondern stellen auch fest: Die Chancen auf weiße Weihnachten schwinden zunehmend und zwar für alle Menschen auf der Erde. Tja.

While precipitation like rain and snow get all the attention, the amount of evapotranspiration - water transferred from land and planets to the atmosphere - is also critical to water management. But there hasn't been an effective tool for farmers, communities, and other water stakeholders to track evapotranspiration. Enter OpenET, a powerful platform that provides easily accessible satellite-based estimates and allows users to explore data down to a quarter-acre resolution or at a broader scale for millions of fields. The development and uses of OpenET is discussed in this episode with Robyn Grimm, Director of Climate Resilient Water Information Systems at the Environmental Defense Fund, and Forrest Melton, Research Scientist at California State University Monterey Bay. Robyn and Forrest talk about building OpenET through a massive partnership, which involves NASA, Google, EDF, the Desert Research Institute, and a variety of federal agencies and universities. They also discuss pilot projects across Western states and how the tool can support irrigation efficiency, groundwater management, and trading programs.Find all episodes at https://www.waterloop.orgwaterloop is made possible in part by grants from the Walton Family Foundation and Spring Point Partners. waterloop is sponsored by High Sierra Showerheads, the smart and stylish way to save water, energy, and money while enjoying a powerful shower.

Satellite imagery is everywhere. We see it on TV news and weather coverage, in our Twitter and Facebook feeds, and on our phones' mapping apps. The data behind that imagery is nothing like a screenshot, though. It's comprised of tiny packets of data, broken down from huge files and digitally manipulated to resemble the surface of the Earth, a swirling storm system or a map of urban growth. Cloud computing resources can make it easier to work with huge datasets that cover long periods of time, which is why many remote sensing scientists are using it for their analyses. On this episode of Eyes on Earth, we hear from a scientist who used the cloud for a 150-year water use modeling project, and from a data scientist working to help train others to use cloud resources.

Brazil is a fascinating study in water use. Brazil uses roughly 72 percent of its water for irrigated agriculture, and its herds of cattle, pigs and poultry are among the largest in the world. Water management teams from that country's National Water Agency have worked in recent years with researchers from the USGS EROS Center to learn how to map, and therefore more effectively manage, the South American country's water resources. On this episode of Eyes on Earth, we hear from the Brazilian water experts and one of their collaborators at EROS.

The Green Revolution leaned on fertilizers, drought-resistant seeds and other modern innovations to boost agricultural production across much of the planet in the second half of the 20th Century. But many of those innovations never reached West Africa, partially because the lack of social safety nets and crop insurance made such investments too risky. On this episode of Eyes on Earth, we hear about a new product called index insurance that could help encourage yield-boosting investments by small holder farmers in West Africa, and how EROS data might be used to refine and improve the product.

Green Roof Plants - How do They Survive Written and narrated by Dr. Anna Zakrisson for Purple-Roof. www.purple-roof.com/ _____ Do green roof plants matter? Yes, absolutely! The vegetation on a green roof is a central part of the engine that drives evapotranspiration. Evapotranspiration helps to ensure efficient green roof stormwater management. Also, if the roof isn’t covered by a protective layer of vegetation, the soil might simply blow away or even flush away during a rainfall. Selecting green roof plants The choice of green roof plants is important and should be carefully considered. The layer of vegetation should be selected based on climatic region and be well-tailored to the soil. Vegetation and soil are closely linked, and healthy soil biology is essential for happy plants. If the vegetation layer crashes, the functionality of the roof is destroyed. ______ Read the article on the Purple-Roof blog! https://www.purple-roof.com/post/green-roof-plants-how-do-they-survive ____ Don't hesitate to contact us if you have any questions or feedback! info@purple-roof.com

What is Evapotranspiration Part 2: Green roofs are tricky. On the one hand, we want evapotranspiration to be very high to get rid of stormwater as quickly as possible and prepare to absorb the next storm. On the other hand, we want the plants to conserve water to not dry out in the thin soil media between storms. We also do not want to have to irrigate green roofs to support plants. It is a challenging task to design a plant palette that minimizes the need for additional irrigation. LEED, in particular, is giving the green roof designer a tough time balancing the desire for native plants, in a very shallow soil profile, and yet at the same time forbid irrigation. This shows the importance of using different roof systems for different climates and abandoning the current strategy of one-size-fits-all for soil and vegetation.

If you would like to read the article, it is available here: https://www.purple-roof.com/post/what-is-evapotranspiration Evapotranspiration is merely a combination of the words: evaporation (evapo-) and transpiration (-transpiration). But what do these two terms mean? Let’s start with evaporation!
