Dataset
Summary
The positions of the meteorological towers (IMKMT1 to IMKMT4) are identical with the positions of the launching sites of the drop-up-sondes (IMKRS1 to IMKRS5). There have been no more than 4 teams operating on each IOP. For detailed information about the sites (including a map) and operating days see supplement pdf-file (cops_rsdu_imk_info_1).

The parameters are:
air_pressure: measured at about 1.8 m GND by a barometric pressure sensor that has a gill pressure port, 60s mean.
air_temperature_at_1.8m: measured at about 1.8 m GND by a HYGROMER meteorology probe MP 400a, 60s mean.
relative_humidity_at_1.8m: measured at about 1.8 m GND by a HYGROMER meteorology probe MP 400a, 60s mean.
precipitation_amount: measured by a tipping bucket rain gauge (catchment area: 200 cm**2), 60s accumulated.
wind_speed_at_4.5m, wind_from_direction_at_4.5m, virtual_temperature_at_4.5m: measured at about 4.5 m by a Young 3-D Sonic Anemometer, 60s mean.

Description
(according to the manufacturer's instructions)
air_pressure: the sensor's accuracy is 0.3 hPa at 20 deg C, 1 hPa at -50 to +60 deg C. The Gill Pressure Port reduces the effects of wind at the barometer inlet to 0.5 hPa max. at 20 m/s.
air_temperature_at_1.8m: accuracy 0.3 %
relative_humidity_at_1.8m: at 23 deg C: accuracy 1% rel. humidity at 5 to 95 %, 2 % rel. humidity for lt 5 % and gt 95 %.
precipitation_amount: 1 % accuracy up to 25 mm/h, 3 % accuracy above 25 mm/h
wind_speed_at_4.5m: accuracy is 1% rms 0.05 m/s at 0 to 30 m/s, 3 % rms at 30 to 40 m/s.
wind_from_direction_at_4.5m: accuracy is 2 deg at 1 to 30 m/s, 5 deg at 30 to 40 m/s.
virtual_temperature_at_4.5m: accuracy is 2 deg C at 0 to 30 m/s wind speed.
