Measurement of Temperature and Energy Flow in Earth – Atmosphere Interface

This paper presents first results which were obtained from mobile device developed for measurement of flow of energy in nature which was developed and built within the project NVP II MŽP,  ev. num.: 2B06023. The device measures absolute and comparative values of temperature, humidity, direction and velocity of wind 30 m above the ground. Aim of these measurements is to assess the influence of sun radiation on different types of growth. Methods and instrumentation for measurement of radiation temperatures, air temperature above the growth, and surface temperatures in Domanin vrt area were compared. Measurement was performed on 2.-3.10.2011. Presented results and long-term pilot monitoring enable better understanding of physical nature of events which occur at the interface soil-atmosphere at a meadow with growth of different heights.
