"This notebook provides an introduction to dust forecast data from the MONARCH model. The notebook introduces you to the variable `Dust Optical Depth` and you will learn how the model has predicted the **Saharan Dust event** which occured over Europe in the first half of April 2024.\n",
"\n",
"The WMO Sand and Dust Storm Warning Advisory and Assessment System (SDS-WAS). is an international framework linking institutions involved in Sand and Dust Storm (SDS) research, operations and delivery of services.\n",
"\n",
"The framework is organised in several regional centers, which aim to implement SDS-WAS objectives in a specific region. The Barcelona Supercomputing Center (BSC-CNS) and the Meteorological State Agency of Spain (AEMET) are hosting the SDS-WAS regional center for Northern Africa, Middle East and Europe.\n",
"\n",
"One of the main activities of the SDS-WAS regional center is to provide daily operational dust forecasts for Northern Africa (north of the equator), Middle East and Europe. The BCS-CNS, in collaboration with NOAA's National Centers for Environmental Prediction (NCEP), the NASA's Goddard Institute for Space Studies and the International Research Institute for Climate Society (IRI), has developed MONARCH, an online multi-scale atmospheric dust model intended to provide short and medium-range dust forecasts for both, regional and global domains. \n",
"\n",
"The model provides forecast information up to 72 hours in advance (every 3 hours) of two parameters: `Dust Optical Depth` and `Dust Surface Concentration`.\n",
"\n",
"MONARCH Forecast data are available in `netCDF` format and are available for download via a THREDDS Data Server here."
