SIGMET Data Help

US AIRMET/SIGMET Data

This will request CONUS based AIRMET and SIGMET text. The data can be filtered on hazard type and region.

URL Options

Here is a list of the URL options:

  • type={all|conv|turb|icing|ifr} - This specifies the type of SIGMET to display.
    • all - All hazards on plot (Default)
    • conv - Only convective SIGMETs and outlooks
    • turb - Only turbulence AIRMETs/SIGMETs
    • icing - Only icing AIRMETs/SIGMETs
    • ifr - Only IFR and mountain obscuration AIRMETs
  • region={all|bos|mia|chi|dfw|slc|sfo} - This specifies the region the SIGMET is valid for.
    • all - All regions (Default)
    • bos - NE - Boston
    • mia - SE - Miami
    • chi - NC - Chicago
    • dfw - SC - Dallas Fort Worth
    • slc - MT - Salt Lake City
    • sfo - WC - San Francisco

International SIGMET Data

This will request international SIGMET text. The data can also be filtered on hazard type and region. International SIGMETs are encoded differentl and thus are not decoded by the ADDS AIRMET/SIGMET decoder which only handles CONUS based reports.

URL Options

Here is a list of the URL options:

  • type={all|conv|turb|ice|mtw|sand|trop|ash} - This specifies the type of SIGMET to display. The default is all.
    • all - All hazards on plot (Default)
    • conv - Only convective SIGMETs and outlooks
    • turb - Only turbulence SIGMETs
    • ice - Only icing SIGMETs
    • ifr - Only IFR and mountain obscuration SIGMETs
    • sand - Only dust and sand storm SIGMETS
    • trop - Only tropical SIGMETS
    • ash - Only volcanic ash SIGMETs
  • region={all|asia|aust|afr|eur|namer|samer|pac} - This specifies the region the SIGMET is valid for. The default is all.
    • all - All regions (Default)
    • asia - Asian region. FIR ICAO identifier starts with O,R,U,V,Z
    • aust - Australian region. FIR ICAO identifier starts with A,W,Y
    • afr - African region. FIR ICAO identifier starts with D,F,G,H
    • eur - European region. FIR ICAO identifier starts with B,E,L
    • namer - North American region. FIR ICAO identifier starts with C,K,M,T
    • samer - South American region. FIR ICAO identifier starts with S
