Minerals in erodible soils and aerosol
SEEVCCC is performing a research in specifying global distribution of key minerals in potentially erodible soils and long-range transport of minerals carried by desert dust (Nickovic, 2010). There are different impacts of minerals to climate, environment and health:
- Direct effects to atmospheric radiation
- Indirect effects by influencing cloud generation
- Nutrient effects in marine ecosystem
- Influence to human health (asthma, cardio-vascular problems, carcinogenic effects, meningitis outbreaks)
GMINER30 is a high-resolution global database on mineral fractions in potentially erodible soils. GMINER30 is developed to support parametrization of mineral emissions in atmospheric dust models. It contains data on illite, kaolinite, smectite, calcite, quartz, feldspar, hematite, gypsum and phosphorus fractions distributed over clay and silt aerosol populations on 30 arc-seconds (~1km) grid (Nickovic et a.l, 2010).
FERRUM30 is a high-resolution global database on Iron fraction in potentially erodible soils. Its development is based on the knowledge gathered from various papers on Iron content in different minerals. More on this subject can be found in the references bellow (latest Nickovic et al. 2013, submitted).
GMINER30 and FERRUM30 are implemented in DREAM-Iron model which simulates atmospheric transport and deposition of iron embedded in dust aerosol (Nickovic et al., 2013; Nickovic et al. 2011).
