i. Ground-based radar used by the meteorological service to supplement its knowledge of current conditions, varying from thunderstorm to upper-wind locations.
ii. A primary airborne radar designed to locate turbulent clouds within a wide area ahead of the aircraft to discriminate between safe and potentially turbulent areas in cloud formations. It provides a pictorial representation of turbulent and dangerous clouds located along the flight path and warns the pilot well in advance. The secondary function of the radar is to aid navigation by using the map-painting mode and avoiding high ground. Airborne weather radars operate in the SHF (superhigh frequency) band, whose wavelength lies between 10 and 3 cm.

Weather radars often also detect airborne animals and other biological material (collectively termed 'biometeors'), but this information is often ignored by weather data users.
weather radar network now known as Nexrad is mostly built around the need to predict the kind of severe weather pilots don't want to fly in (i.e., thunderstorms, tornadoes, hail, etc.).
Justin Schanck, Corporate Project Manager at CERTON, stated, "CERTON will leverage our demonstrated expertise in safety-critical engineering and direct experience on the RTA-4218 Weather Radar to work directly with Rockwell Collins to obtain approval for both the airborne software and electronic hardware on the WXR-2100A Weather Radar product.
The IHAS 5000 and IHAS 8000 (with weather radar) was focused at higher-end piston twins and even light turboprops, although some single-engine Cessna pistons had the IHAS as standard.
The selection includes Rockwell Collins' MultiScan Threat Detection System, which is a fully automatic airborne weather radar system that combines the latest weather science with advanced engineering concepts to identify and analyse thunderstorm cells, and display the weather threat.
By harnessing weather radar, satellite-based damage analysis, ultra-high-resolution aerial imagery, and ground surveys, Atmospheric and Environmental Research (AER), Xactware, and AIR Worldwide produce data, analytics, and modeling that give insurance professionals a deeper understanding of tornadoes and help to get storm victims back on their feet as soon as possible.
"The Meteorological Directorate at the ministry has incorporated the latest technology available at an international level into weather forecasting and climate services, such as weather radar and the operations station for forecasting, as well as a comprehensive database for weather information," he said.
The system, essentially a weather radar for ash, was created by Dr Fred Prata of the Norwegian Institute for Air Research (NILU) and involves placing infrared technology onto an aircraft to supply images to both the pilots and an airline's flight control centre.
The carrier will be the first airline to trial a new "weather radar for ash" system.
Like most other airliners, the Boeing 737 is equipped with its own onboard weather radar which the pilot may have used to avoid flying into thunderheads.
"Severe flooding in recent years and the effect of climate change has led us to join forces with the Met Office and the Environment Agency to install a weather radar at High Moorsley, Sunderland.
