Developing an Aerosol Layer Height Retrieval Algorithm for Passive Space-Based Sensors

Aerosols are the source of the largest uncertainties in our climate models, blurring our outlook of the future. This has been attributed to the complexity of measuring their properties, which vary over time and space. Atmospheric circulation spreads aerosols across the globe from a point source, which makes satellite-based observations lucrative...

Indexing and Retrieving Voice Recordings by Instantly Tagging Mentioned Objects with Dots

This paper presents a novel framework and its prototype tool for indexing and retrieving specific fragments of voice recordings obtained during discussions about physical objects such as text documents, pictures, or 3D models. When a specific part of an object is mentioned, it is tagged with an ink dot that is immediately registered in a...

The impact of aerosol vertical distribution on aerosol optical depth retrieval using CALIPSO and MODIS data: Case study over dust and smoke regions

Global quantitative aerosol information has been derived from MODerate Resolution Imaging SpectroRadiometer (MODIS) observations for decades since early 2000 and widely used for air quality and climate change research. However, the operational MODIS Aerosol Optical Depth (AOD) products Collection 6 (C6) can still be biased, because of...

The Sensitivity of AOD Retrieval to Aerosol Type and Vertical Distribution over Land with MODIS Data

This study is to evaluate the sensitivity of Aerosol Optical Depth (AOD <i style="box-sizing: inherit; line-height: inherit; max-height: 100000px; color: rgb(34, 34, 34); font-family: Arial; font-size: 13px; text-align: justify;">τ</i>) to aerosol vertical profile and type, using the Moderate Resolution Imaging Spectroradiometer (MODIS)...

The Extended Nijboer-Zernike Diffraction Theory and its Applications

In present-day society, we encounter optical systems on a daily basis. Most people have a DVD player capable of playing content stored on an optical disc, Big Brother is watching us nearly everywhere using surveillance cameras and we consider it to be normal to take photographs with our mobile phone. Also, in less visible areas, such as...

Seismic and electromagnetic interferometry: Retrieval of the earth's reflection response using crosscorrelation

One of the goals of exploration geophysics is to obtain an image of the subsurface. In petroleum exploration and near-surface geophysics, this is best achieved using reflected waves. For this, a controlled seismic or electromagnetic source is placed at the surface, activated, and the wavefields that it creates are recorded at the surface after...
