The global distribution and seasonality of dust emissions are reasonably well constrained, but certain data sources cause dust emissions to be under-estimated and this under-estimation may be particularly biased towards particular types of dust events. For example, field measurements of dust emissions are valuable for quantifying at-a-point characteristics of dust, including dust mass, vertical uplift and dust attributes such as size and nutrient content. Scaling up field measurements of dust emissions to determine their regional or global impact is challenging and in some cases the solution to that is satellite remote sensing. However due to their size, timing or dispersal characteristics, some regionally and/or cumulatively significant dust events can go undetected by satellite imagery. This is a particular challenge that needs exploring for high latitude dust source regions (≥50°N and ≥40°S), most notably the Arctic.
This project will integrate ground-based and satellite datasets to determine how different data sources represent Arctic dust events, with the goal to understand the data limitations and hence how under- or over-estimation of dust may be accounted for. Understanding the biases and errors associated with these different data sources will enable the establishment of criteria for fine-tuning estimates of total regional dust loading in high latitude areas.
