This paper is the edited translation of the paper "A. Berson's Bericht über die aerologische Expedition des königlichen aeronautischen Observatoriums nach Ostafrika im Jahre 1908" (Report by A. BERSON about the aerological expedition of the Royal Aeronautic Observatory to East Africa in 1908) that was published 1910 in the Meteorologische Zeitschrift 27, 536-542. The paper, provided by R. SURING, co-editor of the journal, is a summary of a more extensive report published in the same year. © by Gebrüder Borntraeger 2013. Source

The article focuses on a device for the ventilation of the wet-bulb thermometer. It is absolutely necessary to ensure a constant ventilation of the psychrometer and to determine factor A for the selected set-up of the psychrometer by comparison with dew point instruments. For small velocities, the constant has to be determined for every psychrometer and if possible under the same conditions as the later observations. The method described becomes more complicated if barometric pressure deviates more strongly from 755 mm. Apart from that, it seems more recommendable to use a generally applicable psychrometric table instead of perpetuating an, albeit simple, calculation. Assuming that, as repeatedly proven by now, thermometers in such well-exposed metal casings exhibit negligibly small radiation errors, it can be concluded that the principle of the aspiration psychrometer can also be used in the case of smaller air velocities.
