For high-resolution radiosonde data in BUFR, about twice as many data points in the vertical are now used. Unfortunately not many high-resolution radiosonde data are available on GTS at the moment. Most of the upper air observations are exchanged on GTS as reformatted TEMP in separate parts A, B, C, D. This practise is not included in the B/C25 Regulations and those observations should be replaced by native BUFR high resolution data as soon as possible to allow the improvement of the observing system which is expected with the introduction of the BUFR format.
The most significant improvement provided at the moment from the NWP point of view is definitely due to the high-resolution radiosonde data and to highlight the importance of this milestone, reached after so many years of work on the TAC to BUFR migration, ECMWF has prepared a the following page summarising the quality of the new high resolution data as compared to the traditional TEMP: Statistics of High resolution BUFR TEMP.
