Dust-model-dichotomous-performance-analysis

Using a collated dataset of >90,000 dust point source observations from 9 drylands studies from around the world to assess the performance of dust emission models. Here we use the albedo-based dust emission model developed by Chappell and Webb (2016) in Google Earth Engine. The outputs from each DPS location are standardised and analysed in Python to describe the dichotomous coincidence of observed dust emission with model simulation. Discussion topics are developed from the empirical cumulative distribution function (ECDF) of wind shear velocity conditions during observed dust emission days and all days. These ECDF are also produced in Python.
