Jp1.28 Examination of Viewing Zenith Angle Dependence on Cloud Heights Derived from Thermal Infrared Satellite Observations

Narrow spectral bands in the thermal infrared (IR) atmospheric window (10-12 μm) are commonly used to derive cloud top heights from passive satellite imagers (Minnis et al., 1998). When the field-of-view (FOV) of a satellite imager, such as the Moderate Resolution Imaging Spectroradiometer (MODIS), is completely cloud-filled, the observed brightness temperature at a particular band Tλ can be ma...

Multi-Observations Initial Orbit Determination based on Angle-Only Measurements

A new approach with the ability to use the multiple observations based on the least square approach has been proposed for initial orbit determination. This approach considers the Earth’s Oblateness by using the developed Lagrange coefficients. The efficiency of the proposed method has been tested in two scenarios. The first scenario is to use the simulated and the second one is to utilize the r...

A Modified Multi-Source Parallel Model for Estimating Urban Surface Evapotranspiration Based on ASTER Thermal Infrared Data

To date, little attention has been given to remote sensing-based algorithms for inferring urban surface evapotranspiration. A multi-source parallel model based on ASTER data was one of the first examples, but its accuracy can be improved. We therefore present a modified multi-source parallel model in this study, which has made improvements in parameterization and model accuracy. The new feature...

Water balance-based actual evapotranspiration reconstruction from ground and satellite observations over the conterminous United States

The objective of this study is to produce an observationally based monthly evapotranspiration (ET) product using the simple water balance equation across the conterminous United States (CONUS). We adopted the best quality ground and satellite-based observations of the water budget components, i.e., precipitation, runoff, and water storage change, while ET is computed as the residual. Precipitat...

Development a split window algorithm to estimate land surface temperature from Sentinel -3 satellite data

Land Surface Temperature (LST) is an important indicator of the study of energy balance models at the earthchr('39')s surface and the interactions between the Earth and the atmosphere on a regional and global scale. To date, different algorithms have been developed in the last few decades to determine the land surface temperature using various satellite images. In this study, a new split window...
