1 - How to subscribe to the H-SAF website and what are the advantages to sign up?
The registration, as well as all data accessible by H-SAF website, are completely free of charge. Registered users are able to receive news and periodic updates on H-SAF (news on products characteristics, on program events, on training courses), and will be able to have access to restricted sections of the website as "H-SAF Download Data Centre" in order to have access to all H-SAF downloadable products.

2 - How to download H-SAF products?
Once completed the registration process, you will get an account through which you can access to the "H-SAF Download Centre". This will allow you to directly access to the H-SAF FTP server (ftphsaf.meteoam.it) from which you can download H-SAF products and PNG images generated in the last 60 days. Furthermore, the "H-SAF Download Centre" allows you to access to the archived products (older than 60 days) by means of an order-based facility. In addition H-SAF products are distributed directly by EUMETSAT trough EUMETCast (NRT distribution) and UMARF (archived products) services. The H-SAF data are freely distributed. However, when using these data in a publication, we request that the following acknowledgement be given : « These data were obtained from the H-SAF operated by EUMETSAT (Darmstadt, Germany) ».
3 - How to download H-SAF archived products (all archived products not more available on the H-SAF FTP Server)?
All products daily generated are collected and are downloadable through the H-SAF FTP server. All products older than 60 days (generated 60 days before today) are deleted from the FTP server and stored in a permanent archive not accessible by FTP connection. The access to stored data is possible by submitting an order accessing to the proper page (http://hsaf.meteoam.it/download-products/download-products-order.php). It is possible to submit a maximum of 10 orders per day for a total maximum size of 20GB.
4 - How to download the PNG-Files of archived products?
The PNG-Files are not stored into permanent archive. PNG-Files are available only for the last 60 days, after this period of time the images will be permanently deleted. It is noted that it in case of need it is possible to generate the relevant image starting from original binary files.
5 - What is the meaning of the state of a product (Operational, Pre-Operational, Development, etc)?
Each product is associated to an operational state following the EUMETSAT guidelines. Here below the list of product’s state and their definition:
- Operational: products with documented non-relevant limitations that largely satisfy the requirements applicable and/or have been considered by the relevant Steering Group mature enough for distribution to users
- Pre-Operational:Products with documented limitations that are able to satisfy the majority of applicable requirements and/or have been considered by the relevant Steering Group suitable for distribution to users
- Development: Products that are in development and not yet available to users
- Demonstrational: products that are provided to users without any commitment on the quality or availability of the service and have been considered by the relevant Steering Group to be useful to be disseminated in order to enabling users to test the product and to provide feedback
- Auxiliary Product: not operational products; for internal/auxiliary/research/development use
6 - How to access the products' documentation and which documents are available on the website?

More in detail, The "utilities" directory contains two sub-directories:
- "bufr_decode": with all you need to decode BUFR file format for products H01nr and H02Anr (instructions in "Bufr_use.doc") ;
- "Grib_decode": with all you need to decode GRIB file format for products H03A, H04A, H05A, H06, H15A (instructions in "README.doc")
8 - How to read/decode soil moisture product H14 (SM-DAS2) coded in GRIB format?
