The changing urban system of resorts is characterized by a tendency towards a decrease in the volume of arborous phyto-resources of urban gardening involved in the environmental protection function of the environment, the appearance of pathogenic effects, the nature of which has not been sufficiently studied.There have been considered some results of route landscape-climate monitoring in the southern region of the Caucasian Mineral Waters (the Russian Federation) by the methods adopted in balneology [1]. The subject of the study was the modules of the resort and recreational potential (RRP) in the experimental urbanized (open) and natural park areas (in the shade) at heights of 600, 800 and 1000 m above the sea level.The obtained results indicate significant territorial differences in the values ​​of integral RRP in urbanized and natural areas. Differences between the extreme values ​​ranged from 0 to 2,55 points (out of 3 possible), that is from extremely unfavorable to comfortable conditions. Material analysis showed that in the “weight” ratio, the “pathogenicity” of microclimate of the urban systems had been formed due to differences in landscaping conditions at the experimental sites: by solar illumination (up to 100 lx), by total solar radiation (up to 600 W/m2), by the temperature of geological substate (up to 23-25​​°C), by relative air humidity on the Earth's surface (20%), by natural aeroanions (up to 420 ion/cm3), by the percentage of the minimum permissible level of anions (> 400 ion / cm3, up to 60%), by breathing ground-level aerosol pollution with a particle diameter of less than 1000 nm, penetrating to the alveoli (by 10-50%) when breathing, by terms of hypoxia (up to 10-20 g/m3 - 5-10%).Conclusion: the obtained results indicate the dominant role of greening in the correction of microclimate modules and resort-recreational potential in urban mountain resorts. When developing urban planning standards for mountain resorts, it is necessary to provide a special type of urban landscaping aimed at reducing the area of stone coverings of buildings due to their vertical landscaping, increase in the “green shade” over urban pedestrians through the installation of "tent gardening" as well as bringing urban tree planting to 40-60% of the resort area.References: 1.Resort study of Caucasian Mineralnye Vody region / Under the general edition of the prof.

Extracting globally representative trend information from lower tropospheric ozone observations is extremely difficult due to the highly variable distribution and interannual variability of ozone, and the ongoing shift of ozone precursor emissions from high latitudes to low latitudes. Here we report surface ozone trends at 27 globally distributed remote locations (20 in the Northern Hemisphere, 7 in the Southern Hemisphere), focusing on continuous time series that extend from the present back to at least 1995. While these sites are only representative of less than 25% of the global surface area, this analysis provides a range of regional long-term ozone trends for the evaluation of global chemistry-climate models. Trends are based on monthly mean ozone anomalies, and all sites have at least 20 years of data, which improves the likelihood that a robust trend value is due to changes in ozone precursor emissions and/or forced climate change rather than naturally occurring climate variability. Since 1995, the Northern Hemisphere sites are nearly evenly split between positive and negative ozone trends, while 5 of 7 Southern Hemisphere sites have positive trends. Positive trends are in the range of 0.5–2 ppbv decade–1, with ozone increasing at Mauna Loa by roughly 50% since the late 1950s. Two high elevation Alpine sites, discussed by previous assessments, exhibit decreasing ozone trends in contrast to the positive trend observed by IAGOS commercial aircraft in the European lower free-troposphere. The Alpine sites frequently sample polluted European boundary layer air, especially in summer, and can only be representative of lower free tropospheric ozone if the data are carefully filtered to avoid boundary layer air. The highly variable ozone trends at these 27 surface sites are not necessarily indicative of free tropospheric trends, which have been overwhelmingly positive since the mid-1990s, as shown by recent studies of ozonesonde and aircraft observations.
