I want to quantify the impacts of LAI changes (or “greening”) and stomatal closure on ET changes in FLUXNET sites. Are there any recommended statistical methods？
Evapotranspiration (ET) is a key component of the water cycle, and its measurement and analysis are important for understanding hydrological processes. Statistical methods can be used to analyze evapotranspiration at the site scale, such as fluxnet data. Fluxnet data is a network of micrometeorological towers that measure energy and water exchange between the land surface and atmosphere. This data can be used to calculate ET rates at different timescales, from hourly to seasonal. Other statistical methods such as regression analysis can also be used to examine relationships between ET and other environmental variables such as temperature, humidity, wind speed, and precipitation. Additionally, remote sensing techniques such as satellite imagery can be used to estimate ET over large areas.
