Tidal modulation of ice streams and their adjacent shelves is a real-world experiment to understand ice-dynamic processes. We observe the dynamics Priestley Glacier, Antarctica, using Terrestrial Radar Interferometry (TRI) GNSS. Ocean tides are predominantly diurnal but horizontal GNSS displacements also oscillate semi-diurnally. The oscillations strongest in shelf tidal signatures decay near-l...

Accurate estimation of latent heat flux (LE) is critical in characterizing semiarid ecosystems. Many LE algorithms have been developed during the past few decades. However, the algorithms have not been directly compared, particularly over global semiarid ecosystems. In this paper, we evaluated the performance of five LE models over semiarid ecosystems such as grassland, shrub, and savanna using...

This study evaluates seven evapotranspiration models and their performance in water balance studies by using lysimeter measurement data at the Mönchengladbach hydrological and meteorological station in Germany. Of the seven evapotranspiration models evaluated, three models calculate actual evapotranspiration directly using the complementary relationship approach, i.e. the CRAE model of Morton, ...

Accurate estimation of the satellite-based global terrestrial latent heat flux (LE) at high spatial and temporal scales remains a major challenge. In this study, we introduce a Bayesian model averaging (BMA) method to improve satellite-based global terrestrial LE estimation by merging five process-based algorithms. These are the Moderate Resolution Imaging Spectroradiometer (MODIS) LE product a...

Introduction Learning outcomes have become ubiquitous within worldwide curriculum policy in recent years. This move comes with many potential benefits, as it shifts the focus from providers to users of education, and it introduces a common language, addressing issues of progression, transparency and equity (CEDEFOP, 2009). To a large extent, they continue a long tradition of framing curriculum ...

This article models the relationship between a response time series, fYtgt2Zand an explanatory time series fXtgt2Z. We hope that any model we choose might be interesting in its own right but we shall also be interested in using it to predict future values of Yt from future values of Xt. When both time series fall into the class of ARMA type models then it is appropriate to use \transfer functio...
