Measuring evapotranspiration (ET) to understand water loss from a native or a managed ecosystem is easier than it looks, but you have to know what you’re doing. If you can’t spend the time or money on a full eddy-covariance system, you’ll have to be satisfied with making some assumptions using equations such as Penman-Monteith.
Like any model, the accuracy of the output depends on the quality of the inputs, but do you know what measurements are critical for success? Plus, as your instrumentation gets more inaccurate, the errors get larger. If you’re not careful, you can end up with no idea what’s happening to the water in your system.
In this recorded webinar, Campbell Scientific scientist, Dr. Dirk V. Baker, and METER Group scientist, Dr. Colin Campbell, team up to discuss fundamentals, assumptions, required measurements, common pitfalls, accuracy, uncertainty, and much more.
