Evapotranspiration Derived from Satellite Observed Surface Temperatures

Exploring Machine Learning to Correct Satellite-Derived Sea Surface Temperatures

Machine learning techniques are attractive tools to establish statistical models with a high degree of non linearity. They require a large amount of data to be trained and are therefore particularly suited to analysing remote sensing data. This work is an attempt at using advanced statistical methods of machine learning to predict the bias between Sea Surface Temperature (SST) derived from infr...

A continuous satellite-derived global record of land surface evapotranspiration from 1983 to 2006

Surface Emissivity Derived from Multispectral Satellite Data

Surface emissivity is critical for remote sensing of surface skin temperature and infrared cloud properties when the observed radiance is influenced by the surface radiation. It is also necessary to correctly compute the longwave flux from a surface at a given skin temperature. Surface emissivity is difficult to determine because skin temperature is an ill-defined parameter. The surface-emitted...

Gravity acceleration at the sea surface derived from satellite altimetry data using harmonic splines

Gravity acceleration data have grand pursuit for marine applications. Due to environmental effects, marine gravity observations always hold a high noise level. In this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. On the one hand, harmonic spline functions have great capability for local gravity ...

Satellite-derived Sea Surface Temperatures – a Case Study of Error Variability

In situ measurements of skin and bulk sea surface temperatures have been obtained during a cruise of the RV Southern Surveyor during June 2006. Comparisons with satellite-derived estimates of SST show error variability that may lead to a better understanding of the role of the ocean surface and atmospheric conditions in contributing to the in situ/satellite differences. During the first half of...
