Martha conducts research on mapping water, energy, and carbon land-surface fluxes at the field to continental scales using thermal remote sensing, with applications in drought monitoring, agricultural water management, and yield estimation. She and her team have developed the ALEXI/DisALEXI multi-scale ET modeling system. She is currently a member of the Landsat and ECOSTRESS Science Teams. Her participation on the team represents an in-kind contribution to the project, with additional support from NASA for field research.
