Dust storms are common in northern China and can adversely affect the environment human health. The Xilingol grassland is main source of dust China. However, impacts different surface features on dusty weather League remain unclear. This study analyzed temporal spatial variation characteristics corresponding effects using data from 13 meteorological stations, MODIS normalized difference vegetat...

Interception of photosynthetically active radiation (PAR) was evaluated relative to greenness and normalized difference [MSS (7 5)/(7 + 5)] for five planting dates of wheat for 1978-79 and 1979-80 at Phoenix, Arizona. Intercepted PAR was calculated from leaf area index and stage of growth. Linear relationships were found with greenness and normalized difference with separate relationships descr...

Abstract Density and undeveloped land can be identified using digital transformation through remote sensing data. This study aims to map the distribution of building densities with Normalized Difference Built-Up Index (NDBI) Urban (UI), analyze comparison NDBI UI methods, relationship between on in Banjarmasin City. The data used obtain density image Landsat 8 Oli Tirs. method separate built ar...

Six urban subjects, with little or no previous experience of farm-work, were exposed to dust while weighing swine for 2-5 h. Three subjects experienced toxic symptoms 4-5 h after the beginning of exposure. Bronchial responsiveness increased in all subjects within 6 h (more than three doubling steps difference in a methacholine test). One week later, airway responsiveness had partly normalized. ...

mineral dust can directly affect the solar and terrestrial radiation in both visible and infrared (ir) spectral regions through scattering and absorption processes. due to specific optical properties of dust particles, satellite observed radiances carry the spectral signatures of dust particles that are different from molecular, cloud, and underlying surface. based on these differences, various...
