WebThe tool also derives an unsupervised land cover classification for the footprint area and overlays the footprint climatology with the classification, providing you with a … Flux footprint (also known as atmospheric flux footprint or footprint) is an upwind area where the atmospheric flux measured by an instrument is generated. Specifically, the term flux footprint describes an upwind area "seen" by the instruments measuring vertical turbulent fluxes, such that heat, water, gas and momentum transport generated in this area is registered by the instruments. Another frequently used term, fetch, usually refers to the distance from the tower when describi…

WebNov 17, 2015 · Flux footprint models are often used for interpretation of flux tower measurements, to estimate position and size of surface source areas, and the relative contribution of passive scalar sources ... WebJun 1, 2024 · The open-source flux footprint prediction (FFP) model was used to calculate the climatological footprint of the EC tower (Kljun et al., 2015). The FFP model accounts for the position, size and contribution description of the surface footprint area. The input variables of the FFP model are WD, v, u ∗, L, and h c.
