Course/Module description:
This course will include lectures, lab sessions and projects for individual and/or group student work.
Advanced topics in agricultural micro-meteorology: atmospheric flow, boundary layers, laminar and turbulent flow, diffusion of momentum, heat and humidity, and the eddy covariance method. Momentum transfer and the mixing layer. Distribution of radiation in plant canopies, and measurement of canopy structure. Concepts in evapo-transpiration like equilibrium and decoupling. Isohydric and anisohydric control.
The labs will give hands-on experience with data collection equipment for measuring temperature, humidity, wind, radiation and crop water use. Advanced measurement systems, and building sensors.
Projects include measurement and data collection, analysis of data series from the field and lab. Two large projects, one on evapo-transpiration models, and the second on trunk sap flow measurement.
The grade will be derived from lab reports, project reports and an exam.
Course/Module aims:
This course supplements the basic course in agricultural meteorology. It gives a basic understanding of the measurements methods and equipment in that field. Electronic concepts necessary for carrying out measurements along appropriate measurements and projects.
Learning outcomes - On successful completion of this module, students should be able to:
1. To plan and assemble a meteorological station for agrometeorological research.
2. To understand and use agrometeorological equipment. To build some sensors.
3. To analyze data of eddy covariance and sap flow measurements.
4. To program a datalogger and collect data.
5. To understand and use the Penman-Monteith Equation.
6. To use CROPWAT software to predict crop water use and build an irrigation table.
