The NOAA Portable Cloud Observatory (NPCO) is a ground-based system that profiles clouds using active and remote sensors. It features a millimeter-wave cloud profiling radar (MMCR), a three-channel (21 GHz, 31 GHz, 90 GHz) microwave radiometer, an infrared thermometer, and surface meteorological sensors. The MMCR operates at 35 GHz and collects radar observations at a 45-meter resolution to derive cloud properties. The radiometer measures brightness temperature to determine cloud liquid water content and water vapor. NPCO is housed in a standard 20-foot sea container and can be deployed on land or on research vessels for water-based operations.
