Development of an Quadcopter Unmanned Aerial Vehicle for Atmospheric Remote Sensing
… unmanned aerial vehicle (UAV, a.k.a. drone) for atmospheric remote sensing of temperature, pressure, humidity, and PM2.5 particulate matter quantities. A 3-D printed drone body is designed and flight tuning is performed. An optimal length for an upward extending mast for the drone body is …

High Resolution Spectra of Carbon Monoxide, Propane and Ammonia for Atmospheric Remote Sensing
<p>Spectroscopy is a critical tool for analyzing atmospheric data. Identification of atmospheric parameters such as temperature, pressure and the existence and concentrations of constituent gases via remote sensing techniques are only possible with spectroscopic data. These form the basis of model …

Accelerating Bayesian Computation in Earth Remote Sensing Problems
Earth atmospheric remote sensing is an inverse problem that fits surface and atmospheric models to imaging spectrometer data and is critical to the analysis of the composition and biodiversity of the Earth surface. Current methods for remote sensing generally involve retrieving a point estimate of …

Advanced Prototypes of the Aerosol Limb Imager
… The Aerosol Limb Imager, or ALI, is a candidate remote sensing instrument that will provide this monitoring. ALI is a Canadian developed atmospheric remote sensing instrument specifically designed to be sensitive to aerosol and clouds from the mid-troposphere through the stratosphere. An …

A satellite view of the space-time variability of phytoplankton biomass in the Mediterranean Sea
… context of the reliability of both oceanic and atmospheric remote sensing data, and using the most comprehensive in situ bio-optical dataset over the MED basin. This exercise led to the development of an ad hoc regional ocean colour algorithm, which has then been implemented as standard …

Optical remote sensing of thermospheric emission with the Sky-Calibrated Imaging Photometer
Optical remote sensing of emission lines is a well-established approach to estimating atmospheric parameters. The neutral oxygen 844.6 nm emission line has long been considered a good candidate for estimating the oxygen density in the upper thermosphere due to its brightness and relatively simple …

A multi-sensor approach to the retrieval and model validation of global cloudiness
… have represented a daunting challenge to the atmospheric modeling community from the very beginning. Namely, their far-reaching importance to the energy balance and hydrological cycle of our planet is eclipsed only by the level of complexity at which they are nested within the non-linear …

Primary and secondary emissions from upland fires in Ireland
… was conducted as part of FLARES (Fire, Land and Atmospheric Remote Sensing of EmissionS), a project funded by the Irish Environmental Protection Agency (EPA) to improve the understanding of Irish upland fire emissions. Emission factors (EF) of typical Irish wildfire fuels (heather, gorse, purple …

Calibration of Jicamarca radar using F-region incoherent scatter for measurements of D-region backscatter RCS
This thesis presents calibrated radar measurements of absolute backscatter cross sections of mesospheric radar echoes observed at the Jicamarca Radio Observatory in Perú. Radar system calibration is accomplished by simulating the propagation of transmitted and backscattered radio waves through the …

A nonlinear least squares inversion to the single-scattering three-dimensional radiative transfer equation for satellite-based tomography
… radiation measurements. The algorithms used for remote sensing from passive satellite instruments are outdated. For example, all state-of-the-art retrieval algorithms that are in operational use for retrieving cloud and aerosol properties assume the radiative transfer to be one-dimensional (1-D). …
