| Zusammenfassung |
| This paper describes the effect of missing sounding reports on temperature
and pressure mean values for mandatory levels using the aerological
information from the Camagüey Meteorological Centre. Also it is
described the effect of missing data on mean temperature and pressure values
at the multiple tropopause levels. The case study belongs to one station for
a time lag of eight years. Up to the present these types of studies have
been conducted using simulated datasets. The present one uses a real
inhomogeneous radiosonde dataset. The main reason for missing reports were
transmission problems and possible encoding-decoding difficulties. It has
been found that profiles of the mean temperature and altitude show little
differences between the complete and incomplete datasets. Moreover, no
statistical significant differences were found for the mean values of the
variables for the complete and incomplete datasets. The most probable reason
for those results is that the cause of the missing reports has a random
behaviour. Finally we have found that the only two effects noticed on the
statistics were slightly higher values of the mean temperatures in the
complete dataset and the decrease in the percent of multiple tropopause
reports for the incomplete dataset. |
