COSMOS: the COsmic-ray Soil Moisture Observing System

TL;DR: The COsmic-ray Soil Mois- ture Observing System (or the COSMOS) as mentioned in this paper was developed to measure the neutrons generated by cosmic rays within air and soil and other materials, moderated by mainly hydrogen atoms located in soil water, and emitted to the atmosphere where they mix instantaneously at a scale of hundreds of meters and whose density is inversely correlated with soil moisture.
Journal ArticleDOI

Parameter estimation of a land surface scheme using multicriteria methods

TL;DR: In this paper, the potential for using the various observational data sets that are now available to extract plot-scale estimates for the parameters of a complex LSS via advanced parameter estimation methods developed for hydrological models is explored.
Journal ArticleDOI

Sensitivity analysis of a land surface scheme using multicriteria methods

TL;DR: A complementary procedure is presented that provides an objective determination of the multicriteria sensitivity of the modeled variables to the parameters, thereby allowing the number of calibration parameters and hence the computational effort to be reduced.
Journal ArticleDOI

Surface flux measurement and modeling at a semi-arid Sonoran Desert site

TL;DR: In this paper, the authors used a set of site-specific parameters, including on-site observations to specify more realistic soil and vegetation characteristics, and optimized minimum surface resistance and plant wilting parameters, resulted in a substantial improvement in model performance.
