A biologically-inspired approach to designing wireless sensor networks [PDF]

open access: yes, 2005
In this paper, we contend that there are significant advantages in treating some classes of sensor networks as biological-like systems-- both in structural design characteristics and in operational processes.

Impact of Using a New High-Resolution Solar Reference Spectrum on OMI Ozone Profile Retrievals

open access: yesRemote Sensing, 2021
We evaluated a new high-resolution solar reference spectrum for characterizing space-borne Ozone Monitoring Instrument (OMI) measurements as well as for retrieving ozone profile retrievals over the ultraviolet (UV) wavelength range from 270 to 330 nm ...

TROPOMI aerosol products: evaluation and observations of synoptic-scale carbonaceous aerosol plumes during 2018–2020 [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
TROPOspheric Monitoring Instrument (TROPOMI) near-ultraviolet (near-UV) radiances are used as input to an inversion algorithm that simultaneously retrieves aerosol optical depth (AOD), single-scattering albedo (SSA), and the qualitative UV aerosol index (

COMPORTAMENTO DA COLUNA TOTAL DE DIÓXIDO DE ENXOFRE NA CAMADA LIMITE DA REGIÃO DA CIDADE DE SANTIAGO NO CHILE UTILIZANDO O SENSOR OMI [PDF]

open access: yesCiência e Natura, 2016
Air pollution is a major environmental problem of today's world. The sulfur dioxide gas (SO2), a pollutant studied both in remote areas as in urban areas, and can be emitted into the atmosphere through natural sources and also by human activities, and its study of great relevance for monitoring problems caused to health of the population, agriculture ...

Characterising low-cost sensors in highly portable platforms to quantify personal exposure in diverse environments [PDF]

open access: yesAtmospheric Measurement Techniques, 2019
Abstract. The inaccurate quantification of personal exposure to air pollution introduces error and bias in health estimations, severely limiting causal inference in epidemiological research worldwide. Rapid advancements in affordable, miniaturised air pollution sensor technologies offer the potential to address this limitation by capturing the high ...
