| Zusammenfassung |
| The observational systems utilised during the
TRACT experimental campaign (September 1992) can roughly be divided into:
existing climate stations and towers: background chemical monitoring stations;
aerological measurements; instrumented aircraft; and special micrometeorological
stations operated only during the experimental period. Database 4, which
contains the latter surface measurements, includes station descriptions and data
from 21 sites operated by nine different groups during the campaign period.
These data will be described briefly. There are a number of advantages in using
a relational database for analysis of this data. Without creating an
unnecessarily large database which is awkward to view and slow to process,
specific measurements can be selected easily since data from each site have been
standardized using a common time index. This allows comparison of the same or
different variables from one or more sites for investigating data quality or the
effects of site location. Data can readily be combined into hourly or daily
averages or time series for comparison with other data sets (e.g. model or
aircraft data). Spatial analysis is also straightforward, although the
clustering of the sites in the centre of the investigation area means that care
must be taken. Some preliminary comparisons are made here in order to
demonstrate the availability and reliability of the data. |
