This dataset contains 5 sensitivity experiments performed using the WRF-CHEM model simulating a dust outbreak that occurred in June 2019. The dust outbreak occurred over North-Africa and reached over the Atlantic to Middle America. The data was used to investigate how explicitly resolving smaller-scale structures of dust storms impacts the PV power estimate.
WRF was used in a regional setup: The first domain (d01) has a horizontal resolution of 10km and the second (inner) domain (d02) has a resolution of 2km. D01 spans from 48°N to 39°N and from 88°W to 38°E - so North Africa over the Atlantic to Central-America. D02 covers Northwest-Africa from 15°N to 36°N and from 20°W to 25°E (see Fig. 1). D01 is initialised and forced by ERA5, where the forcing data is updated every six hours.
The 5 different simulations share the same setting besides the dust parameterization. Namely GOCART, AFWA, UoC1, UoC2 and no dust scheme. Only UoC2 was run with the d02 domain.
These simulations are still being analyzed in preparation for a publication. For the current status please contact Stephanie Fiedler (sfiedler at geomar dot de)
A pdf describing the current status (as of 12/2023) of the analysis is included in the archive (WRF_doc.pdf).
