The numerical dust forecasts of both the BSC-DREAM8b and NMMB/BSC-Dust models are accessible from this page.

The available modelled data consists in diagnostic simulations of the BSC-DREAM8b (v1.0 and v2.0), and NMMB/BSC-Dust over Northern Africa, the Mediterranean and the Middle East. The simulated dust distributions consist of daily runs in 24-hour daily forecasts. The meteorological fields are initialized every 24h (at 0UTC) and boundary conditions are updated every 6h with the NCEP/FNL Final Operational Global Analysis data (1° x 1°). Since there are not yet satisfactory three-dimensional dust concentration observations, the initial state of dust concentration in the model is defined by the 24-hour forecast from the previous-day model run. The model at the starting day is run using “cold start” conditions, i.e., the zero-concentration initial state.

These long-term series do not correspond with the daily dust forecast shown in the BSC website. They have been rerun in order to provide to the users long-term homogeneous simulations for their purposes.

NetCDF Software Tools

There are many resources for accessing netCDF files. The following is a list of software tools and programs for working with netCDF files divided into two groups: command line interfaces and GUI interfaces. The list is not exhaustive but is a good first start in finding the tools you need. The first tool listed is from Unidata, the creators of the netCDF format; after that, all other tools are listed in no particular order.

Command Line Interfaces

Ncdump
Ncdump is the netCDF file reader that is bundled with Unidata's netCDF product. To obtain it, visit the UCAR Unidata Web site.
NetCDF Operators (NCO)
The NCO is a suite of programs known as operators in which each operator is a standalone, command line program which is executed at the UNIX command prompt. To learn more and to download the operators, visit the NCO Homepage.

GUI Interfaces

Ncview
Ncview is a netCDF visual browser that allows the user to visually inspect NetCDF data files. To download ncview, visit David Pierce's Ncview Web page.
Panoply
Panoply is a JAVA application developed by NASA for viewing netCDF files. For more information and to download a copy, visit NASA's Panoply netCDF Viewer Web page.

Instructions

You can filter your request and significantly reduce the download time using the inputs and selectors that you will see on the sliding menus at the right. Here is some help about how to use them and adjust your query to get the information that better fits your needs.

Variables
It is possible to choose any number of variables, selecting them from the combo box.
Time subset
You may select a time range to obtain exactly the time steps that you want.
Spatial subset
There exist two ways of specifying the spatial subset:
Bounding Box
You can type both the latitude and longitude range, or resize/drag the blue rectangle over the map, to get only the information within this area.
Point
You can select one only point, typing its coordinates or dragging the marker where you want. In this case, the grid cell containing the requested point will be used. You can also specify the vertical coordinate, for obtaining the closest vertical slice to the one you write.
Output
Finally, if you have chosen one only point for the spatial subset, you will have the option of getting the data in CSV or XML format, besides the NetCDF option that you always have. If this is your case, you will have the data displayed on your browser. If you want to save it on your computer you will have to use the browser's "Save as..." function and name the file with the correct extension.

If you have any problem, please, feel free to contact us.
