The GOES-R Advanced Baseline Imager (ABI) Cloud Top Temperature product contains an image with pixel values identifying the atmospheric temperature at the top of a cloud layer. The product is generated in combination with the Cloud Top Height 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 temperature value is kelvin. The product image 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 under the following conditions: cloudy; Geolocated source data to local zenith angles of 70 degrees for both daytime and nighttime conditions.
The Cloud Top Height algorithm will use ABI infrared bands to simultaneously retrieve Cloud Top Height, Cloud Top Temperature, and Cloud Top Pressure for each cloudy pixel. These cloud products are a prerequisite for generating other downstream products that include the Cloud Layer product, Cloud Optical/Microphysical products, and the Derived Motion Wind products. Forecasters will be able to use this information to determine areas of cloud growth and likelihood of precipitation. Other operational applications of this product include its use in Aviation Terminal Aerodrome Forecasts (TAFs), supplementing upper-level cloud information to the ground-based Automated Surface Observing System (ASOS), and initialization of clouds in numerical weather prediction models.

dataset
These data were produced by the NOAA Office of Satellite and Product Operations (OSPO) and are archived at the NOAA National Centers for Environmental Information (NCEI).
The Cloud Top Temperature, Cloud Top Pressure, and Cloud Top Height products are generated by the GOES-R ABI Cloud Top Height ground processing algorithm. The Cloud Top Height algorithm is an important component of the GOES-R ground processing precedence chain as the output of the algorithm is used in the generation of other ABI Level 2+ products. The algorithm retrieves a state vector composed of cloud top temperature, channel 14 emissivity, and band 15/14 beta ratio. It is retrieved using an optimal estimation technique. Cloud top pressure and height are then derived from cloud top temperature. The channel 14 emissivity and band 15/14 beta ratio are output as intermediate products. Pixels in the product image with out of range values are assigned the minimum or maximum value in the valid range. Cloudy conditions are determined using cloudy and probably cloudy pixels indicated in the temporally coincident intermediate 4-level cloud mask generated by the Cloud Mask algorithm. The Cloud Top Height algorithm operates on 2 km resolution pixels, generating intermediate temperature, pressure, and height products at this resolution, but the delivered Cloud Top Height and Pressure products are aggregated to 4 km or 10 km as needed to satisfy end user product resolution requirements.
