Mapping Extent Dynamics of Small Lakes Using Downscaling MODIS Surface Reflectance
Remote Sensing, 2017 Lake extent is an indicator of water capacity as well as the aquatic ecological and environmental conditions. Due to the small sizes and rapid water dynamics, monitoring the extent of small lakes fluctuating between 2.5 and 30 km2 require observations ...

Interpolation and Gap Filling of Landsat Reflectance Time Series [PDF]
IGARSS 2018 - 2018 IEEE International Geoscience and Remote
Sensing Symposium, 2020 Products derived from a single multispectral sensor are hampered by a limited spatial, spectral or temporal resolutions. Image fusion in general and downscaling/blending in particular allow to combine different multiresolution datasets. We present here an optimal interpolation approach to generate smoothed and gap-free time series of Landsat ...

On-Orbit Lunar Modulation Transfer Function Measurements for the Moderate Resolution Imaging Spectroradiometer [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2014 Spatial quality of an imaging sensor can be estimated by evaluating its modulation transfer function (MTF) from many different sources such as a sharp edge, a pulse target, or bar patterns with different spatial frequencies. These well-defined targets are frequently used for prelaunch laboratory tests, providing very reliable and accurate MTF ...

Spatiotemporal Assessment of So2, SO4 and AOD from over MENA Domain from 2006 to 2016 Using multiple satellite Data and Reanalysis MERRA2 Data [PDF]
Journal of Geoscience and Environment Protection, 2019, 7, 156-174
http://www.scirp.org/journal/gepISSN Online: 2327-4344ISSN Print: 2327-4336, 2018 The sulfur pollutants are the source of a sizeable portion of the air pollution. In this work, the spatial distribution and temporal trend of the mass concentration of two of the critical sulfur pollutants, SO2 and SO4, in addition to the aerosol optical properties (AOD) were analyzed over the region of the Middle East and North Africa (MENA) from ...

Waveguide-Type Multiplexer for Multiline Observation of Atmospheric Molecules using Millimeter-Wave Spectroradiometer [PDF]
, 2020 In order to better understand the variation mechanism of ozone abundance in the middle atmosphere, the simultaneous monitoring of ozone and other minor molecular species, which are related to ozone depletion, is the most fundamental and critical method. A waveguide-type multiplexer was developed for the expansion of the observation frequency range of a

A Decade of the Moderate Resolution Imaging Spectroradiometer: Is a Solar–Cloud Link Detectable?
Journal of Climate, 2012 Abstract Based on the results of decadal correlation studies between the International Satellite Cloud Climatology Project–detected cloud anomalies and the galactic cosmic ray (GCR) flux, it has been suggested that a relationship exists between solar activity and cloud cover.
