Improved Estimation Of Pm2.5 Using Lagrangian Satellite-Measured Aerosol Optical Depth, Rolando Olivas Saunders
Improved Estimation Of Pm2.5 Using Lagrangian Satellite-Measured Aerosol Optical Depth, Rolando Olivas Saunders
Theses and Dissertations
Suspended particulate matter (aerosols) with aerodynamic diameters less than 2.5 μm (PM2.5) has negative effects on human health, plays an important role in climate change and also causes the corrosion of structures by acid deposition. Accurate estimates of PM2.5 concentrations are thus relevant in air quality, epidemiology, cloud microphysics and climate forcing studies. Aerosol optical depth (AOD) retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite instrument has been used as an empirical predictor to estimate ground-level concentrations of PM2.5. These estimates usually have large uncertainties and errors. The main objective of this work is to assess the value of …
Reforestation Of Red Spruce (Picea Rubens) On The Cheat Mountain Range, West Virginia, Justin Madron
Reforestation Of Red Spruce (Picea Rubens) On The Cheat Mountain Range, West Virginia, Justin Madron
Theses and Dissertations
The (Plethodon nettingi) Cheat Mountain Salamander is a rare and endangered species that relies heavily on (Picea rubens) Red Spruce for habitat. P. rubens communities on the Cheat Mountain range in West Virginia have been disturbed by fires and logging, and regeneration of P. rubens stands are central to the survival of the P. netting. A supervised and unsupervised landscape classification of three Landsat images over the past 26 years was conducted to analyze change in P. rubens communities on Cheat Mountain Range. Change detection results revealed that from 1986-2012 a 52% growth increase of P. rubens stands, 18% loss, …
