Trial Website "Global SIGMET Monitoring" for Aviation Sector

12 April 2011

The Hong Kong Observatory has developed a trial "Global SIGMET Monitoring" website ( for the International Civil Aviation Organization (ICAO). The website, launched in late March 2011, is to facilitate ICAO and other related organizations to monitor the dissemination and exchange of real-time global en-route significant weather (SIGMET) information. The Observatory developed a SIGMET monitoring webpage for Asia-Pacific region in 2007. As the webpage was well received, the Observatory expanded the webpage to global coverage. Apart from SIGMET, users can also get information from Tropical Cyclone Advisory Centres, Volcanic Ash Advisory Centres and SIGMET Advisory Centres at a glance.
