Ice cloud detection from AMSU-A, MHS, and HIRS satellite instruments inferred by cloud profiling radar

Abstract: An algorithm for ice cloud detection aided by support vector machine (AID-SVM) is presented. The AID-SVM algorithm is applied and tested for the Advanced Microwave Sounding Unit-A, microwave humidity sounder (MHS), and high resolution infrared radiation sounder (HIRS) instruments onboard NOAA-19 satellite. The algorithm is based on satellite brightness temperature measurements and developed as well as validated by using collocated ice/no-ice cloud information acquired from the CloudSat cloud-profiling radar.

“…A similar reasoning may be applied to ice clouds: IR radiation is greatly sensitive to low cloud ice water path (CIWP) while MW radiation is more sensitive to thicker ice clouds with higher CIWP (Sun and Weng, 2012). Therefore, a proper combination of IR and MW measurements would be able to provide useful information over the whole range of cloud water paths and also help in determining the cloud vertical structure, particularly in case of overlapping cloud layers, as suggested by several investigators (e.g., Chevallier et al, 2002;Huang et al 2006;Romano et al 2007;Islam et al 2014).…”

“…However, such a synergy is still under-explored for the retrieval and investigation of cloud microphysics. Despite some previous investigations have demonstrated the feasibility and benefits of MW-IR synergy (Chevallier et al 2002;Huang et al 2006;Romano et al 2007;Islam et al 2014;Holl et al 2014;Maddy and Boukabara 2021), several key parameters for cloud physical processes are not part of the operational level 2 products available from EPS sensors, such as the Advanced Microwave Sounding (AMSU), the Microwave Humidity Sounder (MHS), and the Infrared Atmospheric Sounding Interferometer (IASI). Among the key parameters are the cloud particle effective radius (Re), the profiles of cloud liquid water content (CLWC) and cloud ice water content (CIWC), and their path-integrated cloud liquid water path (CLWP) and cloud ice water path (CIWP).…”

“…Gradient Boosting Decision Tree (GBDT) algorithm achieves the state-of-the-art performance on tabular data (data size less than 1,000, more than 10,000, or even more than 1 million) instead of image data, and the ensemble properties of GBDT may avoid the overfitting. Radar measurements are widely recognized as relatively accurate labels in ML-based cloud classifier models [17]. Compared with the cloud radar, ground-based weather radar has wider temporal and spatial coverage, thus having obvious superiority in collocating with polar-orbiting satellite measurements.…”
