Observation of Cosmic Microwave Background Polarization with BICEP [PDF]

open access: yes, 2009
Background Imaging of Cosmic Extragalactic Polarization (BICEP) is a bolometric polarimeter that has been optimized to target the B-mode of the cosmic microwave background (CMB) polarization at degree angular scales, which is a sensitive probe of the ...

A Physical-Based Algorithm for Retrieving Land Surface Temperature From Moon-Based Earth Observation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Land surface temperature (LST) is a key parameter and plays an important role in hydrology, ecology, environment, and biogeochemistry. It is difficult for the existing satellites to acquire global LST with spatial and temporal consistency. The Moon-based

The Role of the Antenna Radiation Pattern in the Performance of a Microwave Tomographic Approach for GPR Imaging

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
Microwave tomography has been exploited as a successful imaging technique for ground penetrating radar (GPR) surveys. However, an "ideal" antenna model (i.e., a filamentary current element) has usually been adopted so far to describe the involved scattering phenomena.

Interannual Variation of the Surface Temperature of Tropical Forests from Satellite Observations

open access: yesAdvances in Meteorology, 2016
Land surface temperatures (LSTs) within tropical forests contribute to climate variations. However, observational data are very limited in such regions. This study used passive microwave remote sensing data from the Special Sensor Microwave/Imager (SSM/I)

A Simplified Coastline Inflection Method for Correcting Geolocation Errors in FengYun-3D Microwave Radiation Imager Images

open access: yesRemote Sensing, 2023
Passive microwave (PMW) sensors are popularly applied to Earth observations. However, the satellite PMW radiometer data sometimes have non-negligible errors in geolocation. Coastline inflection methods (CIMs) are widely used to improve geolocation errors
