The Campaign
The High Ice Water Content (HIWC) Radar Study was a joint field investigation conducted by NASA and the Federal Aviation Administration (FAA) to gather radar and in situ measurements of high concentrations of ice crystals within deep convective systems. HIWC involved three deployments during the boreal summers of 2015, 2018, and 2022, across Florida, Southern California, Hawaii, and the Atlantic and Pacific Oceans. The NASA DC-8 aircraft was equipped with an X-band radar and additional in situ cloud and aerosol sensors to characterize clouds and precipitation within these deep convective systems. HIWC was funded through NASA’s Advanced Air Vehicles Program and the FAA’s Aviation Weather Research Program.

Radiosondes are a balloon-borne instrument package used to collect profile measurements of pressure, temperature, humidity, and winds. These sensors are connected to a radio transmitter that sends the measurements to a ground receiver typically operating in the 400-406 MHz range. They typically provide measurements at 1-6 seconds, depending on the type and manufacturer of the radiosonde. Radiosondes are used for weather forecasting, ground truth satellite data, atmospheric research, and input for weather prediction models.

The Next Generation Weather Radar (NEXRAD) is a network of high-resolution, S-band radars operated by the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the United States Air Force. NEXRAD measures the magnitude of the returned energy to provide reflectivity, velocity, and spectrum width observations, which can be processed to create mosaic maps of precipitation. NEXRAD radars typically operate with a 0.9-degree beamwidth, 0.25 to 1 km spatial resolution, and a maximum range of 230 to 460 km. Currently, over 160 NEXRAD radars are operating across the United States and some overseas locations.
