Secure Aviation Data Information System (SADIS), which supplies World Area Forecast System (WAFS) and OPerational METeorology (OPMET) data to aviation users in Europe, Africa, and parts of Asia. SADIS is delivered and maintained exclusively by the Met Office.
SADIS is a data library. It does not process/visualise data. It makes data available for extraction, processing and/or visualisation by end user systems.
Two versions of SADIS are currently available, the SADIS FTP (which will be retired in 2028) and the new SADIS API.
