Bhutan to Begin SYNOP Reporting on 6 November 2024

Notification from the National Center for Hydrology and Meteorology (NCHM), Bhutan

The National Center for Hydrology and Meteorology (NCHM) of Bhutan will commence the global distribution of SYNOP data via the WIS/GTS at 06:00 UTC on 6 November 2024. This milestone marks the culmination of two years of system development and observer training, achieved through close collaboration between NCHM, the Japan International Cooperation Agency (JICA), and with support from the World Meteorological Organization (WMO). This is a significant achievement in enhancing Bhutan’s meteorological capabilities.

Updates to the DBNet network

Notification from the WMO Secretariat

Starting from 24/09/2024, ATOVS, ATMS, IASI data from the Edmonton and Gander stations will no longer be relayed by EUMETSAT but instead will be transmitted through NOAA Direct Broadcast Real-Time Network (DBRTN) on the GTS via NOAA NCEP. Additionally, Environment and Climate Change Canada (ECCC) will also begin to disseminate data from its Resolute station, which provides L-band reception only. Resolute data will also be transmitted through DBRTN:

Hong Kong, China to Exchange Higher Resolution TEMP DROP BUFR Data

Notification from Hong Kong Observatory

From 27 June 2024, the dropsonde data collected and disseminated by the Hong Kong Observatory via WIS/GTS during tropical cyclone reconnaissance missions will contain more vertical levels. Comparing with old BUFR which provides weather elements on 16 preset pressure levels, the new files contain data from the entire profile. The same BUFR template 309053 (Sequence for representation of TEMP DROP observation type data) is used for data reporting. A sample can be obtained at https://acnf.weather.gov.hk/tempdrop-bufr-sample/sample.bufr.php for testing.

If you have any questions, please contact Mr. Ping CHEUNG, Senior Scientific Officer of the Hong Kong Observatory at pcheung@hko.gov.hk.
