NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Cloud Top Height (ACHA)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 12, 2026 at 09:21 PM | Dataset Last Updated: February 16, 2018 at 12:00 AM
The Cloud Top Height product contains an image with pixel values identifying the geopotential height at the top of a cloud layer. The product is generated in combination with the Cloud Top Temperature and Cloud Top Pressure products by the same algorithm. The product includes data quality information that provides an assessment of the cloud top height data values for on-earth pixels. The units of measure for the cloud top height value is meters. The Cloud Top Pressure product image is produced on the Advanced Baseline Imager (ABI) fixed grid (at 10 km for Full Disk and CONUS coverage regions and at 4km for Mesoscale) under the following conditions: Cloudy; Geolocated source data to local zenith angles of 70 degrees for both daytime and nighttime conditions. The product's spatial resolution increased from 10 and 4 km to 2 km on 24 March 2023.
