Airport low visibility is spatially heterogeneous, whereas point observations of meteorological optical range (MOR) and runway visual range (RVR) provide certified surface visibility observations but limited information on low-level dynamics and the approach direction of attenuation boundaries. We combined FC-III coher...
Warm-season precipitation over Sichuan, China, is jointly modulated by complex terrain, monsoon water vapor transport, and local convective activities, leading to significant spatiotemporal heterogeneity. However, radar observations over mountainous areas are frequently impaired by terrain blockage, beam shielding, and...
