The occurrence and extent of intense harmful algal blooms (HABs) have increased in inland waters during recent decades. Standard monitor networks, based on infrequent sampling from a few fixed observation stations, are not providing enough information on the extent and intensity of the blooms. Remote sensing has great potential to provide the spatial and temporal coverage needed. Several sensor...

Coastal water regions represent some of the most fragile ecosystems, exposed to both climate change and human activities. While remote sensing provides unprecedented amounts of data for water quality monitoring on regional to global scales, the performance of satellite observations is frequently impeded by revisiting intervals and unfavorable conditions, such as cloud coverage and sun glint. Th...

The Moderate Resolution Imaging Spectroradiometer (MODIS) is one of the key sensors among the suite of remote sensing instruments on board the Earth Observing System Terra and Aqua spacecrafts. For each MODIS spectral band, the sensor degradation has been measured using a set of on-board calibrators. MODIS also uses lunar observations from nearly monthly spacecraft maneuvers, which bring the Mo...

Lake Constance is the third largest lake in Central Europe. The river Rhine, which passes the lake, imports a significant amount of mineralic particles. Their transport and sedimentation within the lake is of importance for a number of applications, for example ship traffic, pumping stations for extraction of drinking water, hydraulic engineering, fishery, and ecology. Only satellites offer a c...

Recent studies have explored the relationship between aerosol optical depth (AOD) measurements by satellite sensors and concentrations of particulate matter with aerodynamic diameters less than 2.5 μm (PM2.5). However, relatively little is known about spatial and temporal patterns in this relationship across the contiguous United States. In this study, we investigated the relationship between U...

Accurate estimation of snow albedo is essential for monitoring the state of the cryosphere. The high albedo of snow-covered surfaces allows little energy to be absorbed by the snowpack. However, as snow ages and/or begins to melt the albedo decreases and more energy is absorbed by the snowpack. This paper examines the retrieval of snow albedo from the MISR and MODIS instruments over the Greenla...

Abstruct-In order to use a wrist-mounted sensor (such as a camera) for a robot task, the position and orientation of the sensor with respect to the robot wrist frame must be known. We can find the sensor mounting position by moving the robot and observing the resulting motion of the sensor. This yields a homogeneous transform equation of the form A X = XB, where A is the change in the robot wri...

Abstract. Sea surface temperature (SST) is an important geophysical parameter that essential for studying global climate change. Although sea can currently be obtained through a variety of sensors (MODIS, AVHRR, AMSR-E, AMSR2, WindSat, in situ sensors), the values by different come from ocean depths and observation times, so products lack consistency. In addition, thermal infrared have many inv...

abstract particular matters which are referred as pm contents in air are one of the main indexes in air pollution studies. pms are consisted of water, solid particles with aerodynamic radius less than 10 micrometer or less than 2.5 micrometer. the main aim of this study is to find possibility of the usage of modis images for estimation of pm10 concentration of dust storms. to achieve this goal ...
