List of required software functionalities

For a software package to receive a 'Y' as opposed to a 'N' in the 'Available and Compliant' column on the table, all of the functions detailed need to be satisfied for each functionality item.

For every workstation provider that is happy for their software to be tested under these criteria, it is our intention to make the information available to all existing and prospective SADIS users via the SADIS web page.

List of required software functionalities — as agreed by SADISOPSG/6, refined by SADISOPSG/8, and updated by SADISOPSG/10 and SADISOPSG/13.

1. Display of OPMET data

  • The ability to receive and display OPMET data and other data types in text format (including TAFs, METARs, SPECIs, SIGMETs, EUR region AIRMETs and GAMETs, and ASHTAMs and NOTAMs related to volcanic ash).
  • The ability for a user to display OPMET for aerodromes specified by the user.
  • Prompt users of the arrival of a SIGMET, SPECI, ASHTAM and NOTAM related to volcanic ash.

2. GRIB decoder and display package

  • The ability to receive and display GRIB data, sourced from WAFC London and WAFC Washington.
  • The functionality to enable a user to produce a wind-temperature chart from the GRIB data over a configurable user-specified area. Global coverage is required. The ability to produce charts spanning the International Date Line and including all of the standard ICAO areas is required.
  • A 'zooming facility' for GRIB chart areas.
  • The ability to produce a wind-temperature chart from GRIB encoded data that is identical as far as the meteorological content is concerned and largely identical as far as other features (e.g. the position of text boxes) are concerned to the wind and temperature example chart contained in Appendix 1 of Amendment 74 to ICAO Annex 3. The product must clearly display whether the chart is derived from the WAFC London or WAFC Washington GRIB encoded data.
  • Automatic chart production is required, i.e. human intervention is not required to modify a chart to ensure compliancy.

3. BUFR decoder and display package

  • The ability to receive and display WAFS SIGWX BUFR data, sourced from WAFC London and WAFC Washington.
  • The functionality to enable a user to produce a SWH and a SWM SIGWX chart from BUFR data over a configurable user-specified area. Global coverage for the SWH data is required. The ability to produce charts spanning the international date line and covering all of the standard ICAO areas is required for the SWH data.
  • A 'zooming facility' for BUFR chart areas.
  • A de-clutter facility for tropopause heights, whereby the quantity of tropopause data plotted over an area is appropriate to the size of the area, and hence maximises the clarity of the end product.
  • The ability to produce a SIGWX chart from BUFR encoded data that is identical as far as the meteorological content is concerned (including depiction of non-CB cloud areas and jetstream depth notation), identical as far as the chart legend box text, and largely identical as far as other features (e.g. the position of text boxes) are concerned to a standard portable network graphics (PNG) SIGWX chart for the same area, and meets the latest ICAO Annex 3 requirements. The product must clearly display whether the chart is derived from WAFC London or WAFC Washington BUFR encoded data. If the software allows the user to modify any of the plotted meteorological parameters, reference to either WAFC must be automatically removed if such modification is carried out by the end user.
  • The ability to handle BUFR bulletins that contain no data, i.e. bulletins that are empty apart from message header information. In particular, this applies to the BUFR bulletins associated with surface fronts, namely: JUFE00 EGRR, JUFE00 KKCI, JUJE00 EGRR; and JUJE00 KKCI.
  • Automatic chart production is required, i.e. human intervention is not required to modify a chart to ensure compliancy.

4. Display and ability to prompt users of the arrival of chart corrections
