IGARSS 2015 - 2015 IEEE International Geoscience and Remote Sensing Symposium
The Geoscience and Remote Sensing Society (GRSS) seeks to advance science and technology in geoscience, remote sensing and related fields using conferences, education and other resources. Its fields of interest are the theory, concepts and techniques of science and engineering as they apply to the remote sensing of the earth, oceans, atmosphere, and space, as well as the processing, interpretation and dissemination of this information.

2012 European Microwave Conference (EuMC)
Microwave and millimeter wave: active/passive devices, antennas, electromagnetics, bio-interaction, circuits, manufacturing and measurement, MEMS, meta-materials, sensor networks, cognitive radio, 4G communications, space technology and applications.
The goal of MicroRad 2010 is to offer the microwave radiometry community an opportunity to share new research results, instrument designs, innovative techniques and technologies in the field of passive microwave remote sensing. Special attention will be devoted to applications to remote sensing of the environment, particularly land, ocean, atmosphere and cryosphere. The meeting attracts about 125 persons and typically consists of a serial sequence of oral and poster sessions.

Arid and semi-arid rangelands cover a large proportion of the State of Queensland. The remote sensing team of the Queensland Centre for Climate Applications is currently developing operational methods for monitoring two very important indicators of rangeland condition: ground-cover and fire. The monitoring needs for these two indicators are very different. The high frequency, regional scale spatial resolution provided by ...

MMW radiometer is the core equipment of passive MMW remote sensing. As a new type of radiometer, full digital compensatory MMW radiometer can compensate system gain and receiver noise fluctuation by using digital compensatory algorithm. According to the designed full digital compensatory 8mm radiometer, the accuracy analytical method of the designed MMW radiometer system is put forward in this paper.

A Ka band polarimetric radiometer operating at 37 GHz was deployed from the seaward end of a small pier colocated with an X band Doppler scatterometer used to measure the instantaneous wave field. Brightness temperature time series from a small spot on the surface for four linear polarizations were measured: TV, TH, TP, and TM, corresponding to vertical, horizontal, +45°, ...

In this paper, we introduce the combined active/passive (CAP) data product for the Soil Moisture Active Passive mission. We develop the algorithms for a radiometer-only salinity product, a radar-only vector wind product, and a CAP vector wind and salinity product. We show that the performance of the radiometer-only salinity product nears but is still inferior to the Aquarius salinity accuracy ...

The Special Sensor Microwave/Imager (SSM/I) radiometer is practical in monitoring snow conditions for its sensitive response to the changes in snow properties. A single-hidden-layer artificial neural network (ANN) was employed to accomplish this remote sensing task, with radiometric observations of brightness temperatures (Tbs) as input data, to derive information about snow. Error backpropagation learning was applied to train the ANN. ...

This paper presents a new neural network (NN) algorithm for real-time retrievals of low amounts of precipitable water vapor (PWV) and integrated liquid water from millimeter-wave ground-based observations. Measurements are collected by the 183.3-GHz G-band vapor radiometer (GVR) operating at the Atmospheric Radiation Measurement (ARM) Program Climate Research Facility, Barrow, AK. The NN provides the means to explore the nonlinear ...
Geoscience and Remote Sensing Symposium (IGARSS), 2014 IEEE International, 2014
The geophysical model function is generally employed to invert the surface wind speed using scatterometer or synthetic aperture radar (SAR) measurements over the ocean. The GMF relates the normalized radar cross-section (NRCS) to the incidence angle and wind vector. The rain effect on NRCS is not considered in the GMF. In raining areas, the NRCS of the ocean surface is ...

This paper describes a new land use and land cover (LULC) classification method for classifying multi-temporal high-resolution satellite data in large areas. The classification method uses combined value of both reflectance of a pixel and its observation date as an input data, and calculates its probability distribution among all LULC classes via Bayesian inference based on a generative model estimated ...
Geoscience and Remote Sensing Symposium, 2003. IGARSS '03. Proceedings. 2003 IEEE International, 2003
The paper discusses time and space variations of ice cover in the Caspian and Aral seas. We use the synergy of data from active (radar altimeter) and passive (radiometer) microwave instruments onboard the TOPEX/Poseidon satellite, as well as passive microwave data from SSMR and SSM/I sensors. The results indicate significant spatial and temporal variability of ice conditions, with a marked ...
A Crookes Radiometer is billed as an educational toy or a novelty ornament and sold by science???oriented outlets as well as, in less expensive versions, by online retailers such as Amazon. It consists of an airtight glass bulb mounted on a pedestal. It was noted that if radiation pressure were responsible for making the vanes turn, the vanes would turn in the direction opposite to what is actually observed. The brighter in 1879, Osborne Reynolds offered the correct qualitative explanation for the radiometer's rotation based on his theory of ???thermal transpiration??? in a manuscript submitted to the Royal Society. In the mid???nineteenth century, Abraham Lincoln, the only US president to hold a patent felt that ???the patent system added the fuel of interest to the fire of genius". A radiometer based on the principle of radiation pressure was developed by Nichols and Hull in 1901. The original apparatus is at the Smithsonian.
