All basic weather observations in AWS310‑SITE can be selected with options that follow
International Civil Aviation Organization (ICAO) and World Meteorological Organization
(WMO) guidelines. To ensure data quality, built-in algorithms test each measurement. For
each parameter, tests are carried out on the minimum, maximum and step limits, and the
dierent parameters are cross-checked. A built-in testing system also continuously checks
the hardware, and reports immediately if a fault occurs.
All observation data from the sensors is collected in the QML data logger. The QML data
logger calculates basic meteorological variables and transmits all data forward to the AviMet
system, where the data is further processed and displayed to the user.
The system stores data locally to a removable CompactFlash (CF) card, and the data can be
made available to the customer through an RS‑485 serial line connection with a high data
rate. An expansion memory is available for data storage, if the data is not sent to an ancillary
system for further use or is to be stored on the computer hard drive.
