SMOS provides first global soil moisture maps but has some issues to address. Calibration and validation activities are helping address biases in soil moisture retrievals. Algorithm improvements have increased accuracy over forested areas and rough surfaces. Continued algorithm development, additional calibration sites, and collaborations will help improve SMOS soil moisture products.
2013 ICEEFP 3D Tracking Error Analyses_Darin EtheringtonChrista Woodley
To 3-D track acoustically tagged fish with measured certainty, error analyses are needed to verify the tracking system‘s performance. The methods detailed below utilize JSATS cabled hydrophone array systems and acoustic micro-transmitters. These processes are conducted after deployment of the array systems, and verify the positional accuracy of tagged fish movements through the tracking baseline of a detection array.

In this study, hydrological modeling is conducted for the Agusan River Basin (ARB) in Mindanao, Philippines using the Hydrological Simulation Program-Fortran (HSPF) model. The first major objective is to build the HSPF model and the second investigated the streamflow responses at nineteen (19) critical river outlets subjected to climate change and land use change scenarios.
