In the last years different DAQUAMAP2-reports about data within the Global Telecommunication System (GTS) were sent to the respective national weather services. During this stage we were able to refine and improve the new mathematical method of quality control, which is a variational approach close to a local thin plate spline.
But the essential aim of DAQUAMAP is to assess the performance of not only the GTS-data but of all meteorological stations of the participating institutions in order to get a more homogeneous data set for the whole Alpine region irrespective of state borders. So, now a new stage starts as soon as there will be enough data available at the MDC.
Mean sea level pressure, potential temperature, humidity and horizontal wind components (after ending the testing phase) will be checked, flagged and a correction proposal given for each station below 750 msl at each analysis step.
Instead of sending the results only to the data-providers, they will be presented online at:
http://www.univie.ac.at/IMG-Wien/daquamap/frameresults.html
for the MAP data users as soon as the results have been approved by the data providers.
These results contain a statistical summary with characteristics of each station for the different observation times in the diurnal cycle, and a time series plot to visualize the result. This provides an indication of the percentage of gross errors, possible systematic errors (e.g. bias), and of the representativity of each station with respect to the scale which can be resolved by the regional station density.
Additional information by the different data-providers about reasons of unusual behaviour of a station will also be available, which is very important for the users of data from the MDC.
