The SDS-WAS Regional Center for Northern Africa, Middle East and Europe (hereafter RC) supports a model inter-comparison and forecast evaluation, which is based on data files daily exchanged by SDS-WAS partners. From now on we refer to these files as numerical predictions. The RC has implemented two types of services:

• Public, providing access to numerical predictions aged more more than 2 days. Access requires previous registration, which can be requested by email (sdswas@aemet.es) or performed automatically when the option is available.

• Restricted, providing access to all the numerical predictions available for re-distribution, including those aged less than 2 days. Access is normally limited to National Meteorological and Hydrological Services and other institutions contributing actively to the SDS-WAS. Public administrations, research and educational institutions are eligible to access these services in support of specific activities. Applications must be submitted by email (sdswas@aemet.es). They will be evaluated and answered within 30 days of the date of receipt.

Data policy

Commercial users will not have access to the restricted services. Their requests for the latest predictions shall be addressed to the following contacts:

HOW TO DOWNLOAD FILES?

Before downloading files, please register either by clicking on the "Register" link on top-right of the web page or going here. Automatic registration is temporally suspended. Please, email to sdswas@aemet.es to request your user id.

After registering, you can log into the portal and enter all repositories following the links above. In each repository you can find daily files, sorted by year and month. You may download a file by clicking on it, or files of a entire month or year (zipped) by clicking on the "(download all)" link on the right of the month or year.

Downloads can also be scheduled using routines or scripts. For example, you can use the "wget" command (by default in most of Linux/Unix distributions and also available for Windows), as follows:

• For a single file
• wget --user="YOUR_REGISTRATION_EMAIL" --password="YOUR_REGISTRATION_PASSWORD" --auth-no-challenge https://sds-was.aemet.es/forecast-products/dust-forecasts/files-download/MODEL_REPOSITORY/YYYY/MM/YYYYMMDDMODEL_NAME.nc
• For an entire month
• wget --user="YOUR_REGISTRATION_EMAIL" --password="YOUR_REGISTRATION_PASSWORD" --auth-no-challenge https://sds-was.aemet.es/forecast-products/dust-forecasts/files-download/MODEL_REPOSITORY/YYYY/MM/@@download -O FILENAME.zip
• Tip to download the latest file:
• wget --user="YOUR_REGISTRATION_EMAIL" --password="YOUR_REGISTRATION_PASSWORD" --auth-no-challenge https://sds-was.aemet.es/forecast-products/dust-forecasts/files-download/MODEL_REPOSITORY/latest/@@download -O FILENAME.zip

Note that, due to the HTTPS protocol, there is the possibility for download programs to not to be able to recognize the secure certificate. In that case please disable it. In the case of wget you can do it with the --no-check-certificate option. Please feel free to contact us in case of doubts or problems.

TECHNICAL SPECIFICATIONS

Numerical dust forecasts are distributed in NetCDF format. This format was developed and is mantained at Unidata, part of the UCAR (U. S. University Corporation for Atmospheric Research). You can find all technical documentation here.

A list of all main software tools to manipulate and visualize NetCDF files can be found here.

DISCLAIMER
