Název v původním jazyce

Measurement of atmospheric temperature close to the terrain

Popis výsledku v původním jazyce

This article opens a broad topic of temperature measurement to suppress the influence of atmospheric refraction on geodetic measurements. The article's content is limited to the basic view of atmospheric behaviour, specifically, on the measurement of the temperature changes in the atmosphere close to the terrain (height 0-2 m), in which engineering geodesy measurements are commonly performed. For this basic experiment we have chosen a grassy spot on the campus of the Faculty of CTU in Prague. The measurement itself was conceived as a whole-day temperature measurement and registration at a height of 0.5 m, 1.0 m, 1.5 m, and 1.9 m above terrain. The measurement was repeated several times, always with a two-week interval. The first part of the article is focused to the proposed data acquisition equipment in the field. It consists of temperature sensors, a data logger for the registration of measured values and a structure that shields sensors from direct sunlight. The second part summarizes and presents the measured data in graphs and overview tables with a description of the initial measurement conditions and other circumstances. In the last section of the article the data analysis and comparison with assumptions such as temperature stratification of the atmosphere or changes of temperature during the day are made.
