Clouds — those mesmerizing cotton puffs in the sky — cover some 70 percent of the earth’s surface at any given time. While they’re made up of mere water droplets and tiny ice particles, their complexity is reflected in their swift formation and dispersion, and rapidly changing hues. For scientists, clouds represent the biggest source of uncertainty when it comes to understanding climate change. Are they accelerating warming or cooling the earth? Or both? That mystery has prompted current and upcoming satellite missions from the world’s space agencies to...Read full article

    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
    remote sensing
    Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on Earth's surface is gathered from a distance, typically using sensors onboard satellites, aircraft, drones, or other platforms. This technique enables the monitoring and analysis of Earth's surface and atmosphere without direct physical contact. Remote sensing systems capture electromagnetic radiation (such as visible light, infrared, microwave, or radio waves) reflected or...
    augmented reality
    Augmented reality (AR) is a technology that integrates digital information, typically in the form of computer-generated graphics, images, or data, with the real-world environment in real-time. AR enhances the user's perception of the physical world by overlaying or combining digital content onto the user's view of the real world, often through devices like smartphones, tablets, smart glasses, or specialized AR headsets. Key features and principles of augmented reality: Real-time...
