NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Cloud Top Phase (ACTP)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2018-02-22T00:00:00.000+00:00
The Advanced Baseline Imager (ABI) Cloud Top Phase product contains an image with pixel values identifying the presence of cloud in four phase categories. 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.
