Radiation values of the solar spectral range are studied in the mountains (Bavarian Alps) at three neighboring, vertically graduated stations at 740, 1780, and 2964 m a.sJ. Additional to the global radiation, the diffuse radiation from sky and UV-radiation in the range from 310 to 340 nm are recorded. Radiation on a spherical body is measured with Bellani-type pyranometers. Besides the presentation of frequency distributions and daily and annual variations under mean conditions and on clear days, special emphasis was laid on the coherence between the different kinds of radiation and on their dependence from the height above sea level. Finally, the influence of atmospheric parameters is investigated.

Radiation values of the solar spectral range are represented over a period of 5 years at three neighboring, vertically graduated stations at 740, 1780, and 1964 m a.s.1, in the mountains (Bavarian Alps). Additional to global radiation the UV-radiation in the range from 310 to 340 nm and the daily sunshine duration are recorded.

Since 1964, values of the RaB (z14 Pb) as part of the natural radioactivity of the air and as indicator of its radon content, are measured and analyzed in the mountains (Bavarian Alps) at three neighboring, vertically graduated stations at 0.7, 1.8, and 3.0 km a.s.1. Apart from the influence of the daily and annual variation, the differences concerning air mass and wind direction are remarkable. The vertical profile, obtained by the values from the three stations, reveals the exchange processes and permits to deduce an average exchange coefficient, determinant for the intermediate layer, and the integrated total RaB content of the air column. In the period under study, covering the years from 1964-I979, air has been sampled on filters simultaneously three times a day at all stations. Zusammenfassung Ergebnisse synchroner und durchlaufender Messungen der natiirlichen Luftradioaktivit~it 1964-1979 an 3 Stationen in 0,7 bis 3,0 km NN und Riickblick auf die Vorarbeiten ab 1956Werte des RaB (214 Pb) als Teil der nattirlichen Radioaktivit~it der Luft und als Mal~zahl ftir ihren Radongehalt werden seit 1964 im Gebirge (Bayerische Alpen) an drei benachbarren, h6hengestaffelten Stationen in 0,7, 1,8 und 3,0 km NN gemessen und untersucht. Neben dem Einflut~ des Tages-und Jahresganges sind die Unterschiede beztiglich Luftmasse und Windrichtung bemerkenswert. An dem durch die Werte der 3 Stationen gewonnenen Vertikalprofil lassen sich die Austauschprozesse erkennen und ein fiir die Zwischenschicht mal~geblicher durchschnittlicher Austauschkoeffizient und der integrierte Gesamtgehalt der Lufts~iule an RaB ableiten. Im Untersuchungszeitraum von 1964 bis 1979 wurden gleichzeitig an jeder Station t/iglich 3 Ffltermessungen durchgefiihrt.
