The categories, which are consistent with heritage NOAA and NASA cloud products, include: Warm liquid water: liquid water cloud with an opaque cloud temperature greater than 273 degrees K; Supercooled liquid water: liquid water topped cloud with an opaque cloud temperature less than 273 degrees K; Mixed phase clouds: high probability of containing both liquid water and ice near cloud top; Ice phase clouds: all ice topped clouds. The Cloud Top Phase product image data variable also has categories for clear sky and unknown phases. A pixel is classified as having an unknown phase when the retrieval has failed because of missing or bad input data. The product includes data quality information that provides an assessment of the the cloud top phase data values for on-earth pixels. The cloud top phase value is a dimensionless quantity which is provided at 2 km resolution on the ABI fixed grid for Full Disk, CONUS, and Mesoscale coverage regions from GOES East and West. Product data is produced for geolocated source data to local zenith angles of 90 degrees for both daytime and nighttime conditions. The Cloud Type algorithm will use four GOES-R ABI infrared spectral bands to determine four different cloud phases: warm (>0C) liquid water, supercooled liquid water, mixed, and ice. The Cloud Phase product is a prerequisite for generating other downstream products that include Cloud Height, Cloud Optical Properties, Fog Detection/Depth, and Aircraft Icing. The Cloud Top Phase product will enable meteorologists to better monitor and track changes in the water properties of clouds, improve icing forecasts for the aviation community, and aid in improving warnings for severe weather. Cloud Phase product information can also be used in advanced ABI applications such as severe weather prediction and tropical cyclone intensity estimation. onGoing Customer Engagement Branch DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce ncei.sat.info@noaa.gov pointOfContact continual https://www.ncei.noaa.gov/pub/data/metadata/images/C01504.jpg Example of the Cloud Phase product as generated by the GOES-R Cloud Phase algorithm.

The Cloud Top Phase product is generated by the GOES-R ABI Cloud Type ground processing algorithm. The algorithm determines the cloud top phase for pixels identified as cloudy, probably cloudy, and probably clear in the intermediate 4-level cloud mask generated by the Cloud Mask algorithm. Clear sky is determined using clear pixels indicated in the temporally coincident intermediate 4-level cloud mask generated by the Cloud Mask algorithm.
