The Canadian Meteorological Centre (CMC) has participated in a limited way to the TAMDAR Great Lakes Fleet Experiment which started on December 2004. The data has been obtained from the AIRDAT ftp server and processed by the CMC quality control system. The monitoring of TAMDAR meteorological observations includes the possibility of evaluating the quality of the observations of all data combined as well as of individual aircrafts.

A number of programs have been prepared for the monitoring of TAMDAR reports and the results can be seen on a CMC internal web site. The statistics are presented only for data not flagged as "suspect" or "bad" in the BUFR bulletins provided by AIRDAT, however all TAMDAR data are available in our database and are monitored.

Various results of the monitoring with the CMC NWP system will be shown. It was found that the data generally is of good quality, but some really "bad" observations, affecting a few aircrafts, are transmitted without being flagged as "bad" or "suspect". These are identified by our quality control system and seem to be related to some specific problem.
