The first results were published by Professor Ebermayer in 1873 in his celebrated work, "Die Physikalischen Einwirkungen des Waldes auf Luft und Boden."

As regards Atmospheric Temperature. - From observations recorded between 47½° and 49½° latitude, averaging 540 métres (1,800 ft.) above sea-level, and with a mean distance of 900 métres (3,000 ft.) between the edge of the forest and the stations in the open, Ebermayer found the mean annual atmospheric temperature to be cooler in the forest than in the open by -
He also recorded the temperature of the trees themselves, and found that they were invariably cooler than the atmosphere surrounding them during the active period of vegetation, whilst they were occasionally a little warmer during the winter period of inactivity.
