The Atmospheric Infrared Sounder (AIRS) flying on NASA’s EOS-AQUA platform has channels sensitive to both sulfur dioxide (SO2) and nitric acid (HNO3). We have developed a simple regression retrieval for both of these gases that illustrates the potential for AIRS, and other hyperspectral sounders, to retrieve these two gases. We have cross-validated the SO2 retrievals to those from the OMI instr...

AIRS was launched on EOS Aqua on May 4, 2002, together with AMSU-A and HSB, to form a next generation polar orbiting infrared and microwave atmospheric sounding system. AIRS is a grating spectrometer with a number of linear arrays of detectors with each detector sensitive to outgoing radiation in a characteristic frequency vi with a spectral band pass Ovi of roughly vi /1200. AIRS contains 2378...

The intelligent reflecting surface (IRS) is considered a core technology of next-generation mobile communication. It has significant advantages in enhancing network coverage, spectrum efficiency, energy and deployment cost. Compared with the conventional massive multiple-input-multiple-output (MIMO) system, cell-free MIMO overcomes limitation imposed by inter-cell interference traditional cellu...

Coverage analysis is essential for many coverage tasks (e.g., robotic grit-blasting, painting, and surface cleaning) performed by Autonomous Industrial Robots (AIRs). enables (1) the performance evaluation rate operation efficiency) of AIRs a task, (2) configuration design multi-AIR system decision on number to be used). Multi-AIR large complex structures involves addressing various problems. T...

[1] We compare matched retrievals of upper tropospheric water vapor (UTWV) mixing ratios from the Microwave Limb Sounder (MLS) instrument on the Aura satellite, and the Atmospheric Infrared Sounder (AIRS) instrument on the Aqua satellite. Because each instrument’s sampling is affected by tropical conditions, about half of mutually observed scenes in the tropics yield simultaneous successful ret...

Within the debate about heterogeneity of unaccusative structures, aim this paper is to distinguish two types Spanish marked anticausative inherent reciprocals (AIRs) from other syntactic (SRs) with se. Several diagnostics show that AIRs such as mezclarse ‘get mixed’ are symmetric, unaccusative, telic, and causative alternations, while SRs transitive vary in their aspectual properties do not alt...

Intelligent reflecting surfaces (IRSs), active and/or passive, can be densely deployed in complex environments to significantly enhance wireless network coverage for both information transfer (WIT) and power (WPT). In this letter, we study the downlink WIT/WPT from a multi-antenna base station single-antenna user over multi-active/passive IRS (AIRS/PIRS)-enabled link. particular, derive locatio...
