radartietojen
Radartietojen (radar data) are measurements gathered by radar systems that detect and characterize objects or phenomena by emitting radio waves and analyzing their echoes. They are used across meteorology, aviation, maritime, defense, and remote sensing to infer location, motion, and properties of targets such as precipitation, aircraft, ships, or terrain features.
The core information in radar data includes reflectivity, which relates to target size and concentration; radial
Sources of radar data range from ground-based weather radar networks and airborne or shipboard radars to surveillance
Data products can be raw radar returns, gridded precipitation fields, storm tracks, nowcasting guidance, velocity fields,
Applications include weather forecasting and severe-weather warning, hydrology and flood management, aviation weather services, maritime operations,
Challenges in radar data include uneven spatial coverage, beam blockage, ground clutter, attenuation in heavy rain,
