It is defined by the ratio of the third and second moment of the particle size distribution. Separate algorithms are used for daytime, solar zenith angle to 82 degrees, and nighttime, solar zenith angle greater than 82 degrees, conditions. The product is generated in combination with the Cloud Optical Depth product by the same algorithms. The product includes data quality information that identifies whether the daytime or nighttime algorithm generated the pixel, and provides an assessment of the cloud particle size data values for on-earth pixels. The units of measure for the cloud particle size value is microns. Product data is produced under the following conditions for the daytime algorithm: Cloudy; Geolocated source data to local zenith angles of 65 degrees and to solar zenith angles of 82 degrees. Product data generated by the nighttime algorithm is produced under the following conditions: Cloudy; Geolocated source data to local zenith angles of 70 degrees and solar zenith angles between 82 and 180 degrees. The cloud particle size values reported range from 0 to 100 um. However, the size range depends on day/night conditions and the liquid/ice water phase. Cloud Particle Size product data is identified as degraded in the terminator region, which is a solar zenith angle between 65 and 82 degrees for the daytime algorithm, and 82 and 90 degrees for the nighttime algorithm. The measurement range for Cloud Particle Size is determined by the model parameterization used in the algorithm retrieval. For daytime retrievals, the effective radius is determined by the lookup table bounds, 100.4 to 102.0, corresponding to 2.51 to 100 um, for both liquid and ice clouds. For nighttime retrievals, the effective radiance is determined by the range of particle size models considered: 2 to 32 um for water clouds, and; 2.62 to 78.15 um for ice clouds where the retrieval of particle size diameter is related to the effective radius by a quadratic equation. 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. The Cloud Effective Particle Size will be computed using the same algorithm that estimates the Cloud Optical Depth. Using both the visible and near-infrared bands during the day and the infrared bands during the night, the GOES-R Cloud Optical and Microphysical Properties algorithm will retrieve, simultaneously with COD, the Cloud Particle Size. The Cloud Particle Size will provide valuable information about the radiative properties of clouds. 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/C01509.jpg Example of the Cloud Particle Size product as generated by the GOES-R Cloud Optical and Microphysical Properties algorithm.

The Cloud Optical Depth and Cloud Particle Size products are generated by the GOES-R ABI Cloud Microphysical and Optical Properties (COMP) ground processing algorithms for daytime and nighttime. The daytime algorithm employs a physical retrieval based on theoretically computed lookup tables while the nighttime retrieval employs the Community Radiative Transfer Model (CRTM) calculations in an iterative physical retrieval that seeks to minimize the difference between the compute TOA brightness temperature and the observations. The algorithm processes the data pixel-by-pixel, choosing to use the daytime or nighttime approach based on the solar zenith angle threshold value of 82 degrees. The two approaches use different criteria to identify candidate cloudy pixels. The daytime algorithm processes pixels that are identified as cloudy or probably cloudy in the intermediate 4-level cloud mask. In addition to the the intermediate 4-level cloud mask, the nighttime algorithm processes pixels based on the intermediate cloud type product data that is generated by the Cloud Type algorithm. The nighttime processing occurs for any pixel that is identified as cloudy, probably cloudy, or probably clear in the intermediate 4-level cloud mask. However, because the nighttime retrieval requires cloud top temperature product data as input, which is generated only for cloudy, and probably cloud pixels, the nighttime cloud optical depth and particle size are flagged as invalid for pixels identified anywhere the cloud top temperature is invalid. Pixels in the product image with out of range values are assigned the minimum or maximum value in the valid range. The daytime algorithm is limited to local zenith angles below a threshold of 65 degrees. The nighttime algorithm produces degraded quality product data beyond the local zenith angle limit. However, because of the dependency on cloud top temperature, a valid product is restricted to the local zenith angle range for the Cloud Top Temperature product of 70 degrees. The product is generated for all solar zenith angles but is flagged as degraded in the twilight region where the solar zenith angle is between 65 and 82 degrees for the daytime algorithm, and between 82 and 90 degrees for the nighttime algorithm.The Cloud Optical and Microphysical Properties algorithm operates on 2 km pixels, generating an intermediate product at this resolution, but the delivered Cloud Optical Depth product is aggregated to 4 km for the Full Disk coverage region. processor GOES-R Algorithm Working Group DOC/NOAA/NESDIS/STAR > Center for Satellite Applications and Research, NESDIS, NOAA, U.S. Department of Commerce publisher https://www.star.nesdis.noaa.gov/goesr/ HTTPS Web Browser GOES-R Algorithm Working Group The GOES-R Algorithm Working Group creates the algorithms that process the quality controlled satellite instrument data and produces resulting data products. information NOAA Satellite Information System Product Quality https://www.noaasis.noaa.gov/GOES/PS_PVR2.html HTTPS Web Browser NOAA Satellite Information System Product Quality Peer/Stakeholder Product Validation Reviews by satellite and product. information GOES-R Algorithm Theoretical Basis Documents DOC/NOAA/NESDIS/STAR > Center for Satellite Applications and Research, NESDIS, NOAA, U.S. Department of Commerce publisher https://www.star.nesdis.noaa.gov/goesr/documentation_ATBDs.php Web Browser GOES-R Algorithm Theoretical Basis Documents Descriptions of how the algorithms work, their underlying designs, and initial comparison with prior algorithms and results. information See Algorithm Citation The GOES-16 ABI Cloud Particle Size Distribution algorithm reached beta maturity. 2017-06-08T00:00:00 processor The GOES-16 ABI Cloud Particle Size Distribution algorithm reached provisional maturity. 2018-12-14T00:00:00 processor The GOES-16 ABI Cloud Particle Size Distribution algorithm reached full validation maturity. processor The GOES-17 ABI Cloud Particle Size Distribution algorithm reached beta maturity. 2018-08-27T00:00:00 processor The GOES-17 ABI Cloud Particle Size Distribution algorithm reached provisional maturity. 2019-09-24T00:00:00 processor The GOES-17 ABI Cloud Particle Size Distribution algorithm reached full validation maturity. processor Level 1b radiances NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 1b Radiances 2017-07-10 publication Provisional doi:10.7289/V5BV7DSR DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce distributor https://doi.org/10.7289/V5BV7DSR HTTPS Web Browser NCEI landing page for ABI-L1B-RAD Source dataset landing page with general information and access links for the dataset. information 1 -156.2995 6.2995 -81.3282 81.3282 2017-02-28 repository NOAA National Centers for Environmental Information NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235.
