The PSL W-band radar is an air-, sea- and land-deployable vertically pointing cloud radar system that makes measurements of non-precipitating clouds, fog and aerosolized water droplets over a range of 7.5 - 10 km. The radar operates at W-band (94.56 GHz) and uses a 0.3m antenna with an optional stabilizer system used in the ship-deployed configuration.

The radar can be deployed on board the NOAA P3 Hurricane Hunter aircraft. In this configuration, the electronics rack is mounted in the cabin of the aircraft, while the sensor head is mounted below the deck with a down-firing antenna configuration.

In the land- or ship-deployment configuration, the radar is mounted inside a shipping container with an opening on the top and an up-firing antenna configuration. An optional stabilizer platform maintains the beam vertical relative to the horizon, compensating for the roll and pitch of the ship.

Measured outputs include radar reflectivity, Doppler velocity and spectrum width.

The radar is funded by and operated along with the NOAA Physical Sciences Laboratory. When not deployed in the field, the radar is based at the CSU-CHILL main site in Greeley CO.


Deployments

Hurricane Season, 2024

The PSL W-band was installed aboard the NOAA P3 aircraft to observe sea-spray over the ocean during hurricane overpasses during the 2024 hurricane season. The deployment started in June 2024.

The radar's physical packaging was improved for this deployment by replacing several legacy enclosures with modern equivalents to reduce the space taken up by the radar electronics within the aircraft.

Hurricane Season, 2023

The PSL W-band was installed aboard the NOAA P3 aircraft to observe sea-spray over the ocean during hurricane overpasses during the 2023 hurricane season. The deployment was between May and October 2023.
