The haze and health: a blog about the fog.
The haze is an atmospheric phenomenon where pollutant particles accumulate in the air and obscure the normal clarity of the sky. In Singapore, this usually happens when the prevailing southwest monsoon winds blow the smoke from regional forest fires to Singapore. This phenomenon is not new and has been occurring regularly since 1994. In 1997, it featured on the front page of the Straits Times a...
متن کاملJovian Clouds and Haze
At wavelengths from the near-ultraviolet (0.2 μm) to the infrared (5 μm) Jupiter’s appearance is dominated by contrasts produced by clouds and haze. It is important to understand the distribution and optical and physical properties of cloud and haze particles because they play a major role in the radiative heat budget, and they can tell us about atmospheric processes such as stratospheric circu...
متن کاملMobile Haze Removal Application
In this paper, we implement a dehazing algorithm using dark pixel detection in MatLab and C++/OpenCV. The algorithm is originally proposed in Yu et al.’s paper. The simplicity and effectiveness of the algorithm make it possible for us to run the C++/OpenCV implementation on Android phones through android NDK with reasonable speed. Keywords—dehaze; image processing; mobile application; computer ...
متن کاملTemporal variations of black carbon during haze and non-haze days in Beijing
Black carbon (BC) aerosol has been identified as one of key factors responsible for air quality in Beijing. BC emissions abatement could help slow regional climate change while providing benefits for public health. In order to quantify its variations and contribution to air pollution, we systematically studied real-time measurements of equivalent black carbon (eBC) in PM2.5 aerosols at an urban...
متن کاملSize-resolved source apportionment of particulate matter in urban Beijing during haze and non-haze episodes
Additional size-resolved chemical information is needed before the physicochemical characteristics and sources of airborne particles can be understood; however, this information remains unavailable in most regions of China due to lacking measurement data. In this study, we report observations of various chemical species in size-segregated particle samples that were collected over 1 year in the ...
