Remote sensing is a big deal. It helps us see the world from above. But making AI models that work well on edge devices is tough. They need to be small and smart. That's where knowledge distillation (KD) comes in. KD is like having a teacher help a student learn better. But current KD methods aren't perfect. They miss out on important details and don't use all the in...
Northwestern India's Trans-Gangetic Plains (TGP) are vital for the country's food supply, growing lots of wheat and rice. But this area is in trouble. Land is getting worse, and droughts are becoming more common. This is a big deal because not many studies have looked at both problems together. A recent study used satellite data and computer tools to check the healt...
The world needs to know how much food it can expect from its farms. This is especially true for crops like winter wheat. To do this, experts need to know exactly where different crops are growing. This helps them keep an eye on how the crops are doing and predict how much they will produce. However, getting this detailed information during the growing season can be t...
The boreal forest, also known as taiga, is a vast expanse of evergreens. But there is another tree that plays a crucial role in this ecosystem: the aspen. This tree is vital for both forestry and wildlife. However, pinpointing where these trees are can be tricky. This is where technology comes in. Researchers have developed a smart way to map out where aspen trees a...
Imagine looking at the Earth from space. That's exactly what a new technology called MetaEarth does. It creates pictures of our planet from a bird's-eye view. This isn't just any picture. It's a high-quality, detailed image that can show us things we might not see from the ground. MetaEarth can generate images of any place on Earth, at any size, and with different le...
Plants need light for photosynthesis, which is the process that turns light into energy. The amount of light a plant can absorb depends on how much chlorophyll (Chl) it has. Chlorophyll is like the plant's solar panel, and the more it has, the more light it can absorb. This light absorption is crucial for understanding how well plants can photosynthesize and grow. S...
Uruguay's agricultural boom has led to a surge in pesticide use, causing serious environmental problems. The country's wetlands, crucial for conservation, are under threat. To grasp the full extent of this issue, it's essential to understand how pesticides are used, where they end up, and how they move through the environment. Researchers in Uruguay tackled this pro...
Researchers have come up with a smart new way to figure out how much coastal cliffs are eroding. They combined data from drones, satellites, and laser measurements to see how bad the erosion is. This method helps us understand both natural wear and tear on cliffs and damage to protective structures from storms and other extreme weather. By looking at pictures taken ...
Wetlands and deltas are crucial for our planet, especially as sea levels rise. One way they cope is by trapping tiny bits of mud, called suspended solids, to build up their surfaces. Scientists often use special cameras on planes to map these solids. However, the recipes they use to make sense of the camera data don't always work everywhere or at different times beca...
Scientists are always looking for better ways to study changes in our climate and weather. One important tool is satellite data, but getting accurate information for a long time is tough. That's why China started working on a special tool in 2015. This tool, called the Space Cryogenic Absolute Radiometer (SCAR), is helping to solve a big problem with satellite data. ...
