[1] Present-day global anthropogenic emissions contribute more than half of the mass in submicron particles primarily due to sulfate and carbonaceous aerosol components derived from fossil fuel combustion and biomass burning. These anthropogenic aerosols increase cloud drop number concentration and cloud albedo. Here, we use an improved version of the fully(More)
[1] We have analyzed long-term NOAA/AVHRR (Advanced Very High Resolution Radiometer) global data from 1985 to 1994 to investigate the variation of the cloud particle size for low-lying water clouds. Here we focus on seasonal change of the cloud particle size instead of studying the variability the absolute values, since there are several critical factors(More)
Many endemic fish species are threatened with extinction. Conservation strategies and the restoration of endemic fish after extinction must therefore be investigated. Although sperm cryopreservation is indispensable for the conservation of endangered fishes, the limited number of mature fish and limited availability (volume and period) of sperm from small(More)
1 2 This paper studied the behavior of 94-GHz radar reflectivity (Ze) with variation in 3 the properties of low-level water clouds, such as the effective droplet radius (re), 4 geometrical thickness (Dcld), and liquid water path (LWP), over the northwest Pacific 5 and China. The changes in the distribution of maxZe (the largest Ze within a cloud layer) 6(More)
