Sub-basin scale dust source geomorphology detected using MODIS

Dust source identification using MODIS: A comparison of techniques applied to the Lake Eyre Basin, Australia

Mapping erodibility in dust source regions based on geomorphology, meteorology, and remote sensing

Mineral dust in the atmosphere has implications for Earth’s radiation budget, biogeochemical cycles, hydrological cycles, human health, and visibility. Currently, the simulated vertical mass flux of dust differs greatly among the existing dust models. While most of the models utilize an erodibility factor to characterize dust sources, this factor is assumed to be static, without sufficient char...

Dust source mapping using satellite imagery and machine learning models

Predicting dust sources area and determining the affecting factors is necessary in order to prioritize management and practice deal with desertification due to wind erosion in arid areas. Therefore, this study aimed to evaluate the application of three machine learning models (including generalized linear model, artificial neural network, random forest) to predict the vulnerability of dust cent...

Amazon Basin Water Quality Monitoring Using Meris and Modis Data

The use of satellite data to monitor inland water quality in the Amazon basin is investigated. Both floodplain and river main channels are considered using the medium resolution sensors MODIS and MERIS A large database from the HYBAM project gives the water main properties for a large floodplain, 700 km upstream the Amazon river mouth. Parameters measured include the total suspended sediment (T...

dust detection using improved tiidi and applying modis sensor data

introduction thermal infrared integrated dust index (tiidi) is one of indices that is presented in this direction. the index operates based on four brightness temperature difference including wavelengths 3.7, 8.6, 11 and 12 micrometer. according to the studies, btd (bt12-bt11) is used for cloud detection. btd (bt8.6-bt11) is the index for separation for dust from sandy surface and btd (bt3.7-bt...
