Na + concentration ranged from <0.01 to 12.9 mg·L −1 and Cl − from 0.7 mg·L −1 to 18.6 mg·L −1 , higher than the values measured by VIfEP in Wrocław and the whole voivodeship (Na + from 0.01 to 2.6 mg·L −1 and Cl − from 0.05 to 6.5 mg·L −1 ) and from previous studies: Na + from 1.5 to 1.9 mg·L −1 , Cl − from 3.8 to 5.0 mg·L −1 (Kmieć et al 1994) and Na + from 0.9 to 3.2 mg·L…”

“…Absence of substantial differences between liquid and solid deposits of fog is characteristic for Szrenica Mt. (SOBIK, 1999;BłAŚ et al, 2010). The question is why seasonal variations in pollutant emission seem to not influence the chemistry of liquid and solid fog deposits (typical for warm and cold half of the year, respectively).…”

“…Because of altitude, differences in boundary layer depth and much more vigorous circulation, especially during cyclonic weather, the chemistry of fog water collected at Szrenica Mt. may show major contribution from emission sources located at much larger upwind distances (BłAŚ et al, 2010;MÖ LLER et al, 1996). Concentration of ammonia, emitted in main part by agriculture and livestock operations are much lower than the sum of nitrite and sulphate concentration, resulting in only partial neutralization of the existing fog water acidity.…”

“…Concentration of ammonia, emitted in main part by agriculture and livestock operations are much lower than the sum of nitrite and sulphate concentration, resulting in only partial neutralization of the existing fog water acidity. Sulphates, which were the most important constituents of cloud water chemistry in the early 1990s (30%), became the third most important ion, with their actual contribution being two times lower (BłAŚ et al, 2010). Relatively high concentration of nitrates can be clarified by increasing emissions from traffic (ACKER et al, 1998;MITOSEK et al, 2004).…”

Atmospheric pollutants are transferred to the ground by the contribution of various types of hydrometeors. Because of the different techniques of measurement, comparative analyses between them are often neglected. Hence, the main goal is to compare water volume and chemistry of different types of hydrometeors and their role in both: water balance and pollutants deposition. The results of water input and atmospheric deposits chemistry at Szrenica Mt. during the period between 01 December 2008 and 28 February 2010 are presented. The volume-weighted total inorganic ionic content (TIC) of dew, hoarfrost and fog water (both solid and liquid) was 345, 134, 425 leq l -1 respectively, while typical TIC value for precipitation was 233 leq l -1 . The chemical composition of dew, hoarfrost and fog water differ significantly from each other and from precipitation, depending on background emission and atmospheric processes. Taking into account both concentration and volume of deposited water, comparison between pollutant load of hydrometeors was possible.

“…Low stratiform clouds (LSC) are of great importance for a wide range of disciplines including meteorology [1], transportation [2,3], economy [4] and air quality [5,6]. In terms of financial losses, the impact of reduced horizontal visibility associated with the LSC is comparable to tornado damages [7], thus there is a strong need for development of low-cloud monitoring systems.…”

Daytime Low Stratiform Cloud Detection on AVHRR Imagery

The near-real time retrieval of low stratiform cloud (LSC) coverage is of vital interest for such disciplines as meteorology, transport safety, economy and air quality. Within this scope, a novel methodology is proposed which provides the LSC occurrence probability estimates for a satellite scene. The algorithm is suited for the 1 × 1 km Advanced Very High Resolution Radiometer (AVHRR) data and was trained and validated against collocated SYNOP observations. Utilisation of these two combined data sources requires a formulation of constraints in order to discriminate cases where the LSC is overlaid by higher clouds. The LSC classification process is based on six features which are first converted to the integer form by step functions and combined by means of bitwise operations. Consequently, a set of values reflecting a unique combination of those features is derived which is further employed to extract the LSC occurrence probability estimates from the precomputed look-up vectors (LUV). Although the validation analyses confirmed good performance of the algorithm, some inevitable misclassification with other optically thick clouds were reported. Moreover, the comparison against Polar Platform System (PPS) cloud-type product revealed superior classification accuracy. From the temporal perspective, the acquired results reported a presence of diurnal and annual LSC probability cycles over Europe.
