Geoscience and Remote Sensing

Remote sensing of environment research has explored the benefits of using synthetic aperture radar imagery systems for a wide range of land and marine applications since these systems are not affected by weather conditions and therefore are operable both daytime and nighttime. The design of image processing techniques for  synthetic aperture radar applications requires tests and validation on real and synthetic images. The GRSS benchmark database supports the desing and analysis of algorithms to deal with SAR and PolSAR data.

This dataset includes 30 hyperspectral cloud images captured during the Summer and Fall of 2022 at Auburn University at Montgomery, Alabama, USA (Latitude N, Longitude W) using aResonon Pika XC2 Hyperspectral Imaging Camera. Utilizing the Spectronon software, the images were recorded with integration times between 9.0-12.0 ms, a frame rate of approximately 45 Hz, and a scan rate of 0.93 degrees per second. The images are calibrated to give spectral radiance in microflicks at 462 spectral bands in the 400 – 1000 nm wavelength region with a spectral resolution of 1.9 nm.

This dataset contains results of the 60 GHz indoor sensing measurement campaign using a bistatic OFDM radar based on 5G-specified positioning reference signals (PRSs). The data can be used for testing end-to-end indoor millimeter-wave radio positioning as well as simultaneous localization and mapping (SLAM) algorithms, including channel parameter estimation. Beamformed PRS with dense angular sampling in transmission and reception allows efficient capture of line-of-sight (LoS) as well as multipath components.

A method is proposed to reduce the electron density irregularity by injecting chemicals into the scintillation region and attaching electrons by chemical reaction with the background ionosphere. A physical model of ionospheric scintillation mitigation based on the release of electron density depletion chemicals is established. The evolution process of electron density irregularities reduction, plasma instability growth rate and beacon amplitude phase fluctuation before and after scintillation mitigation were simulated.

In our ever-expanding world of advanced satellite and communications systems, there's a growing challenge for passive radiometer sensors used in the Earth observation like 5G. These passive sensors are challenged by risks from radio frequency interference (RFI) caused by anthropogenic signals. To address this, we urgently need effective methods to quantify the impacts of 5G on Earth observing radiometers. Unfortunately, the lack of substantial datasets in the radio frequency (RF) domain, especially for active/passive coexistence, hinders progress.

This dataset comprises multimission altimeter products, specifically multimission altimetry-derived cyclonic eddy trajectories in the South China Sea region (109°E-121°E, 3°N-23°N). These products are released by the Archiving, Validation and Interpretation of Satellite Oceanographic data (AVISO) with the support of the Copernicus Marine Environment Monitoring Service (CMEMS). The eddy trajectories are derived from the "all satellites" constellation maps distributed by CMEMS. The dataset is intended for the study of ocean mesoscale eddies.
