SSEBop evapotranspiration estimates using synthetically derived Landsat data from the continuous change detection and classification algorithm
Mikael Peter Hiestand, Heather J. Tollerud, W. Chris Funk, Gabriel B. Senay, Mackenzie Friedrichs, Kate Fickas
2024, Remote Sensing (16)
The operational Simplified Surface Energy Balance (SSEBop) model has been utilized to generate gridded evapotranspiration data from Landsat images. These estimates are primarily driven by two sources of information: reference evapotranspiration and Landsat land surface temperature (LST) values. Hence, SSEBop is limited by the availability of Landsat data. Here,...

Marcan Graffin, Mohsen Taherkhani, Meredith Leung, Sean Vitousek, George Kaminsky, Peter Ruggiero
2023, Coastal Futures (1)
Coastal morphological changes can be assessed using shoreline position observations from space. However, satellite-derived waterline (SDW) and shoreline (SDS; SDW corrected for hydrodynamic contributions and outliers) detection methods are subject to several sources of uncertainty and inaccuracy. We extracted high-spatiotemporal-resolution (~50 m-monthly) time series of mean high water...
Implementing a dual-spectrometer approach for improved surface reflectance estimation
Mahesh Shrestha, Joshua J. Mann, Emily Maddox, Terry J. Robbins, Jeffrey Irwin, Travis Kropuenske, Dennis Helder
2023, Remote Sensing (15)
Surface reflectance measurement is an integral part of the vicarious calibration of satellite sensors and the validation of satellite-derived top-of-atmosphere (TOA) and surface reflectance products. A well-known practice for estimating surface reflectance is to conduct a field campaign with a spectrometer and a calibration panel, which is labor-intensive and...
