Doppler radar imaging is a remote sensing method that combines conventional radar reflectivity measurements with Doppler-shifted phase or frequency information to retrieve both spatial structure and line-of-sight velocity of targets, typically hydrometeors or atmospheric scatterers. By transmitting coherent microwave pulses and analyzing phase changes between successive returns, it quantifies radial velocities and turbulence, enabling derivation of wind fields, storm dynamics, and microphysical processes. Advanced implementations, such as pulse-pair processing and dual-polarization Doppler techniques, enhance sensitivity to motion, particle type, and size distributions, supporting quantitative precipitation estimation, severe weather diagnosis, and assimilation of high-resolution kinematic data into numerical weather prediction models.
When people think about habitats on Earth, they likely picture forests, oceans or grasslands. Few think to look up. Yet the lower atmosphere, or troposphere, may be the largest habitat on the planet. A new study published ...

After nearly 25 years of research, the mystery has finally been solved: Europe's largest bat doesn't just eat small birds—it hunts and captures them more than a kilometer above the ground. And it eats them without landing.
