“…Some of the orographic effects such as seeder-feeder scavenging are well understood and can be simulated using airflow and precipitation scavenging models (Inglis et al, 1995). However even here, the simple ridge or isolated mountain is much easier to simulate than a mountainous region, and in the latter the inputs are difficult to simulate with models and even harder to validate with field measurements.…”

Abstract. The accumulation of 210 Pb in organic material within the surface (0 to 20 em depth) horizons of soil is used to quantify local variability in the atmospheric inputs through wet deposition, cloud droplet deposition and dry deposition of aerosols. The method has been applied to quantify the long-term (-50 yr) average enhancement in deposition as a consequence of orographic effects on a 800 m mountain in southwest Scotland. The 210 Pb inventory increases by a factor of2.5 up the hillslope and is comparable to the modeled increase in wet deposition of major ions, and larger than the increase in rainfall with altitude by a factor of two. A second study site examined the increase in deposition beneath a Norway spruce canopy relative to open grassland at an elevation of 450 min the Scottish Borders. The inventory of 210 Pb under the forest canopy exceeded that in the grassland by approximately 35 %, in good agreement with deposition estimates obtained from a continuous record of cloud frequency and meteorological variables.
