Figure 1.

TC-based SM/LH coupling strength estimates acquired from a variety of sources over a set of AmeriFlux sites (see Appendix B). Black symbols (“TOWER”) replicate earlier results in Crow et al. (2015) based on using ground/tower-based SM and LH observations (plus Noah SM, Noah LH, PMW SM, and ALEXI-TIR LH) to complete the triplet. Red symbols (“ALEXI-MW”) capture the impact of using ALEXI-MW LH in place of flux tower observations. Blue symbols (“RS-Only”) capture the impact of further replacing ground-based SM observations with AMW SM retrievals (thus eliminating all dependence on ground-based observations). The consistency demonstrates the applicability of selected RS-based SM and LH in place of ground-based data for TC analysis.
