Image segmentation for dust detection using unsupervised ...

Recent dust detection methods also integrated 15-day rolling mean cloud screened BTD for each pixel (Ashpole and Washington, 2012). Moreover, these methods have employed more shortwave (UV, VIS, and NIR) bands to eliminate cloud effects (Miller et al., 2017), aiming to impose multiple fixed thresholds on calculated dust indices (Taylor et al., 2015; Marchese et al., 2017; She et al., 2018 ...

Dust detection, mobilization and transport.

· Electrostatic detection of dust settling on surfaces. ¥ A 30- 50v bias is applied across a grid of interlocking traces on a circuit board. ¥ Impinging conductive dust creates a short circuit and current pulse. ¥ Current pulse is input to nuclear counting electronics and converted to counts. ¥ Number of counts is proportional to mass of dust. ¥ Current also vaporizes or ejects dust from ...

Review of dust storm detection algorithms for ...

· Present dust detection literature mainly uses polar orbiting satellite (such as MODIS) for dust storm detection, since these are sun-synchronous, thereby, detecting dust storms mainly during daytime. With the launch of the new generation geostationary satellites, more attention will be paid on GEOs as it can offer continuous earth observation as well as higher resolution (compared with old ...

Building Better Dust Detection. Throughout the world, dust ...

· The dust detection tool is built using a UNET architecture for the segmentation task in order to utilize the model’s lightweight nature, fast training times, and faster inference relative to other DL image segmentation models. The model leverages convolution in order to learn the features of the image and associate lower level features like gradients with larger features like dust storms.

· The data-denial dust detection methodology described in section 3 is validated by comparing it with a refined version of the Allen et al. dust detection results. The refinement is to allow classification of separate advection and emission periods within individual dust events, rather than classing each event once based on whether it is mostly advecting or emitting dust. This refinement is ...
