Below are plots of radiosonde/SYNOP BUFR coverage for 1-5 August 2014 - reports as decoded at ECMWF, some reports not in standard BUFR are not decoded.
Radiosonde coverage, about 45% of stations report in BUFR, but most (apart from the dark blue stations in the plot) report reformatted TEMP (see "structure" page). Reports may be incomplete (eg data above 100 hPa missing).
(Grey: TAC reports but no BUFR, Purple: BUFR reports but no TAC, Red *: position error. Light/dark blue indicates low/high vertical resolution BUFR data).
(BUFR-only reports from 76903 in Mexico, 04405 - should be 76405, 04692 - should be 76692 and 17516 - duplicate of 17607?)
Surface coverage, over 60% of stations report in BUFR:
(Grey: TAC reports but no BUFR, Purple: BUFR reports but no TAC, Red *: position error. Light/dark blue indicates that there are less/more than 60% of the reports available in BUFR.)
