SCAR Expert Group on Operational Meteorology in the Antarctic

& WMO GCOS Antarctic monitoring


The SCAR Expert Group on Operational Meteorology in the Antarctic is a sub group of the SCAR Standing Scientific Group on Physical Sciences (SSG/PS).  The chair of the Expert Group is Steve Colwell (src@bas.ac.uk).  If you would like to join the Group please contact him. 

The Global Climate Observing System (GCOS) monitoring of Antarctica is carried out by BAS for the WMO.

Jon Shanklin (J.Shanklin@bas.ac.uk), currently maintains these pages. 


Latest news:

  1. 2026 May 4 - MV Hondius, which was in Antarctic waters until March, has an outbreak of hantavirus on board
  2. 2026 April 13 - 55 call signs have made reports and 190 may have not, though call sign masking does duplicate some vessels
  3. 2026 March 2 - 55 call signs have made reports and and 179 may have not, though call sign masking will duplicate some vessels
  4. 2026 February 2 - 51 call signs have made reports and 165 may have not, though call sign masking will duplicate some vessels

Operational GSN stations with missing CLIMAT messages in the last 12 months (2025 April to 2026 March, updated 2026 May) are:  89004 (2025 May, July, August, 2026 February, March), 89262 (2025 May, June, July, August, September, October, November, December, 2026 January, February), 89272 (2025 June, July, August),  89377 (2025 May, June, July, August, September, October, November, December, 2026 January, February, March), 89573 (2025 June), 89577 (2025 March, May, June, July, August, September, October, November, December, 2026 January, February), 89592 (2026 January) and 89879 (2025 May, June, July, August).  Non operational GSN stations are: 68992, 89327, 89345. Although 89577 is reporting SYNOP messages it did not report CLIMAT messages in 2025.  Please check our GCOS AntON CLIMAT and SYNOP monitoring if your station is listed here and resend the data for the missing month(s).  See the latest CLIMATs  to check if your report has been received at BAS. See CLIMAT data for Antarctic AWS for all the University of Wisconsin AWS. The first five stations to submit CLIMAT reports for 2026 April were Halley, Neumayer, Arturo Prat, Novolazarevskaya and Russkaya.

WMO no longer require distribution of the CLIMAT TEMP message and monitoring of these has ceased.  See the TEMP monitoring below for performance.

BAS GTS monitoring
BAS GCOS AntON monitoring:  Where we see problems with receipt of SYNOP, TEMP or CLIMAT messages stations or operators will be notified by email.  Several AWS experience problems with low battery voltages restricting real-time transmissions during the winter.   All GUAN stations are now carrying out at least some radiosonde flights each month.  Several stations experience problems with balloons bursting early during the winter due to low stratospheric temperatures.
