Urban climate is the most modified by humans among local climates. Industry, traffic and
heating emit artificial heat, water vapor and pollution to the atmosphere. Air pollution and air temperature
are becoming ones of the major factors for the quality of life of urban dwellers. The aim of
present paper is to analyze the temperature conditions in Sofia, Bozhurishte and Bankya. For this
purpose long term (1961-2011) meteorological data of their stations were used. The amendment
of certain atmospheric pollutants, observed in southwestern areas of Sofia city - Hipodruma and
Pavlovo, where there is high urbanization, intensive traffic and industrial activity is studied too.
The relationship between pollutants and the temperature has been examined.

In the current study, Psilopezia nummularia, which known as psilopezioid fungi, is a new
record at genus level in Turkey. In addition, this is the first report that relict endemic Liquidambar
orientalis is a host of this species. Macro- and microphotographs of the taxon are given together
with a description.

Very High Resolution local component products provide information on specific land cover
characteristics, which are necessary for land cover/land use mapping. The main objectives of
this study are the Natura 2000 areas on the territories of the Natural Park Rusenski Lom and
the protected area Lomovete. A Dataset and a Sample collection are created and a Validation
exercise is provided, using the open access online portal LACO-Wiki. A specific land cover/land
use nomenclature is used which is fully compatible with the MAES (Mapping and Assessment of
Ecosystems and their Services) nomenclature.

The thematic accuracy is an important data quality element of land cover databases. For this
reason it has been paid a considerable attention by researchers over years. The main aim of this
article is the presentation of the results from verification of the Natura 2000 (N2K) local component
dataset for Bulgaria, which is a part of a project, managed by the European Environmental
Agency (EEA). Following the methodology proposed by EE, we apply a quantitative approach
based on probability sampling at polygon level. Thus, we obtain scientifically rigorous estimate
of the thematic accuracy of N2K layer and of some geometric characteristics as well. Based on
local expertise and in situ data, an evaluation of the quality of this product is made and statistical
results are obtained, comparable to the results in other countries. The results of the verification
show that the overall thematic accuracy is higher than the 85 % level expected at Pan-European
scale.
