Empirical Study of Subauroral Polarization Streams (SAPS) through Decades of Satellite Observations
… ionosphere made by the Defense Meteorological Satellite Program (DMSP) and Dynamics Explorer 2 (DE 2) satellites. We have used these measurements to develop an empirical model of subauroral electric fields which is oriented relative to particle precipitation boundaries instead of by geomagnetic …

Tropical forest structure: Ground measurements of coarse necromass and satellite observations of crown geometry
… was developed that uses high resolution satellite image data. This algorithm was applied to two forests with field based data on forest structure and then applied at seven locations across the Amazon basin. The algorithm provided forest structure based on crown geometry across vast areas …

Shipboard and satellite observations of upper ocean velocity and transport variability in the Gulf Stream
Acoustic doppler velocities are combined with velocity profiles generated from XBT measurements to produce estimates of the flow field between Bermuda and the eastern coast of the United States. Repeated shipboard measurements along an ascending GEOSAT subtrack between Bermuda and Cape Cod allow …

The Study of the Indian Ocean Response to Climatic Events Using Satellite Observations and Model Simulations
<p>The interactions of intraseasonal and interannual climate variability with surface ocean properties is an active area of research in the Indian Ocean region. Understanding how climate variations impact basin-wide salinity patterns is an important step in understanding how this variable impacts …

Oceanic Light Absorption Properties: Assessment and Characterization in the Southeastern Bering Sea Using Field and Satellite Observations
… models and parameterizations currently used in satellite algorithms for the southeastern Bering Sea, which were found to be inapplicable in these waters due to the dominant contribution by CDOM absorption. The CDOM absorption accounted for greater than 50% of the diffuse light attenuation …

A study of Mesoscale Eddies, the Agulhas current and the evolution of its meanders using satellite observations and numerical modelling experiments
… data set with in-situ surface drifter observations and altimetry-derived geostrophic currents, it is shown that source region eddies dissipate upon approaching the Agulhas Current. Their entrainment into the Agulhas Current affects its mean velocity and offshore position through a …

Tropospheric Ozone over the Middle East and Its Interannual Variability: An Integrated Analysis with Satellite Observations and a Global Chemical Transport Model
… understood, mainly due to the lack of adequate observations. One such region is the Middle East, where ozone measurements are scant. In this study, the GEOS-Chem chemical transport model is used to interpret newly available tropospheric ozone data from the Tropospheric Emission Spectrometer …
