Platform for Measurement of Atmospheric Quantities
Hanák, Jiří ; Vlk, Jan (referee) ; Chudý, Peter (advisor)
This work is dealing with the design and implementation of an embedded system for aerology measuring. The aim of the system is to monitor atmospheric states during an ascent in the suspension under an meteorological balloon. First of all, attention is given to the Earth's atmosphere and its quantities, then an overview of existing systems for performing aerological measurements. The core of the work is focused on the choice of measurement techniques and the selection of suitable measuring elements for a given scenario. The aerological probe is using atmospheric sensors HIH-8131-021-001, MS5611-01BA03 and PT1000-550 for temperature sensing, while GNSS data is received using the MAX-M8Q-0 module and the measured data is stored on a microSD card and transmitted in parallel using the MTX2-434.650-10 radio module. The system is controlled by STM32L1 from STMicroelectronics programmed in C using HAL abstraction layer.

Wind shear as a dangerous fenomenon in aviation
Novozámský, Adam ; Jebáček, Ivo (referee) ; Krška, Karel (advisor)
This thesis is about wind shear and its influence on aviation. There is wide theoretical description of wind shear and it’s implemented into aviation practice. There are also methods of observation, forecasting and reporting, for both pilots and meteorologist described. In this thesis, pilots can find useful recommendations for dealing with wind shear during the flight. Every reader can also read about famous aviation accidents and look at models of weather that caused those accidents. At the end of thesis there are analyses of a rawiosonde measurements related to wind shear reports. This whole thesis is focused on increasing awareness of wind shear in aviation from angle of view of both pilots and aviation meteorologist.

Methods of Weather Forecasting and Their Use in Biology at the Lower Secondary School
Vladyková, Martina ; Říhová, Dagmar (advisor) ; Andreska, Jan (referee)
This thesis is dedicated to meteorology and its inclusion in the teaching of biology in primary school. It also focuses on various examples of weather forecasting methods and their subsequent use in teaching. The theoretical part of the thesis introduces basic meteorological concepts, instruments and methods of weather forecasting. It also deals with the history of meteorology and weather forecasting. A large part of the chapter on weather forecasting methods consists mainly of the possibilities of forecasting on the basis of own observations and by means of observations of nature. This section also includes an analysis of textbooks for primary school grades 1 and 2 to provide an overview of the inclusion of meteorology or weather forecasting in science and science education. The practical part of the thesis is aimed at verifying the real use of three methods of weather forecasting (changes): the storm glass, the leech barometer and a simple physical barometer made from a jar and a glass bottle. The final thesis is also devoted to a practical observation in the context of laboratory activities for 6th grade primary school students. The observation was designed to enrich the teaching of the topic of ringworms, which is included in the curriculum of the sixth grade.

Climate change or precursor emissions - which of these will be the major player in future ground-level ozone concentrations?
Tremaskina, Anastasiia ; Hůnová, Iva (advisor) ; Matoušková, Leona (referee)
This thesis examines the reasons for potential future outcomes as well as the evolution of future ground-level O3 concentrations. Ground-level O3 is primarily formed by the reaction of precursor emissions, such as nitrogen oxides (NOx) and volatile organic compounds (VOCs), in the presence of solar radiation and warm temperatures. Transport, industrial operations, and energy production are the primary human activities that produce these emissions. Climate change, on the other hand, also has an impact on ground-level O3 concentrations by modifying the atmospheric conditions that promote O3 generation. The frequency and length of high O3 occurrences, for instance, may increase with increasing temperatures and changes in atmospheric circulation patterns, but drought conditions may decrease plant ability to absorb O3 and other pollutants. Additionally, precursor emissions can potentially be impacted by climate change. For instance, rising temperatures may cause plants to produce more biogenic VOCs, and shifting rainfall patterns may have an impact on soil NOx emission rates. Therefore, both precursor emissions and climate change must be considered and addressed in order to correctly anticipate future ground-level O3 concentrations. The work covers the results of previous studies on precursor emissions...

Planetary Boundari Layer Effect on Vertical Transport of Black Carbon Concentration under Different Meteorological Conditions
Julaha, Kajal ; Zíková, Naděžda ; Mbengue, Saliou ; Ždímal, Vladimír
In the present study, we analyzed the impact of equivalent black carbon (eBC) aerosols at two different heights (4 m and 230 m) on the PBL height under different \nmetrological conditions such as clear sky, foggy (visibility ≤ 1km), and hazy days (visibility ≤ 8km during the non-fog day), high relative humidity, temperature, and \nobservational data, also, diurnal and seasonal variability was evaluated.
