Hemispheric and Seasonal Contrast in Cloud Thermodynamic Phase From A‐Train Spaceborne Instruments

Aerosol-cloud interactions are an important source of uncertainty in current climate models. To understand and quantify the influence ice-nucleating particles cloud glaciation, it is crucial to have a reliable estimation hemispheric seasonal contrast top phase, which believed result from higher dust aerosol loading boreal spring. For this reason, we locate these contrasts by combining three different A-Train cloud-phase products for period 2007–2010. These rely on spaceborne lidar, lidar-radar synergy, radiometer-polarimeter synergy. We show that product combination more has lower error compared individual products. cloud-phase, use difference ice frequency normalized liquid southern hemisphere between −42 °C 0 °C. In midlatitudes, −15 −30 °C, increase with decreasing temperature. At varies 29% 39% 52% 73% combination. Similarly, northern hemisphere, assess spring fall during fall. ranges 21% 54% 75%
