The chapter presents a comparison of results of modelling concentrations of fine dust (suspended dust PM10) in the air with the use of two diffusion models: the Gaussian plume model (used commonly in Poland), and the Gaussian puff model CALPUFF (used significantly less frequently). It indicates discrepancies in obtained results of calculations for point emitters taking into consideration three dimensional options (with the following heights: 20, 40 and 60 m and diameters of respectively: 1.0, 1.5 and 2.0 m). For particular variants, errors were visualised, resulting from use of the simple Gaussian plume model in place of the advanced CALPUFF …

Early Rayleigh-Scatter Lidar Temperature Measurements From The Lower Thermosphere, Leda Sox, Vincent B. Wickwar May 2015

Early Rayleigh-Scatter Lidar Temperature Measurements From The Lower Thermosphere, Leda Sox, Vincent B. Wickwar

Leda Sox

Rayleigh-scatter lidar observations were made on many clear nights at the Atmospheric Lidar Observatory (ALO) at Utah State University (USU) from 1993 to 2004 in the altitude range 45–90 km. An upgraded facility, 66 times more sensitive, has been brought on line. It has resulted in temperature measurements with maximum altitudes that extend into new territory—the lower thermosphere. All-night temperature averages have been recorded up to an altitude of 114 km. Temperatures from each month, starting in June 2014, are presented and discussed. They are compared to each other, to the ALO-USU climatology from the original lidar, and to temperatures …

Global Meteorological Drought – Part 1: Probabilistic Monitoring, Will Pozzi Jan 2014

Global Meteorological Drought – Part 1: Probabilistic Monitoring, Will Pozzi

Will Pozzi

Near-real-time drought monitoring can provide decision-makers with valuable information for use in se- veral areas, such as water resources management, or inter- national aid. One of the main constrains of assessing the current drought situation is associated with the lack of re- liable sources of observed precipitation on a global scale available in near-real time. Furthermore, monitoring sys- tems also need a long record of past observations to pro- vide mean climatological conditions. To address these prob- lems, a novel probabilistic drought monitoring methodology based on ECMWF probabilistic forecasts is presented, where probabilistic monthly means of precipitation were derived from …

Improving The Retrieval Of Water Inherent Optical Properties In Noisy Hyperspectral Data Through Statistical Modeling, David B. Gillis, Jeffrey H. Bowles, Wesley J. Moses Jan 2013

Improving The Retrieval Of Water Inherent Optical Properties In Noisy Hyperspectral Data Through Statistical Modeling, David B. Gillis, Jeffrey H. Bowles, Wesley J. Moses

Wesley Moses

The use of the Mahalanobis distance in a lookup table approach to retrieval of in-water Inherent Optical Properties (IOPs) led to significant improvements in the accuracy of the retrieved IOPs, as high as 50% in some cases, with an average improvement of 20% over a wide range of case II waters. Previous studies have shown that inherent noise in hyperspectral data can cause significant errors in the retrieved IOPs. For LUT-based retrievals that rely on spectrum matching, the particular metric used for spectral comparisons has a significant effect on the accuracy of the results, especially in the presence of noise …

Strategic Incentives For Climate Geoengineering Coalitions To Exclude Broad Participation, Juan B. Moreno-Cruz, Kate L. Ricke, Ken Caldeira Jan 2013

Strategic Incentives For Climate Geoengineering Coalitions To Exclude Broad Participation, Juan B. Moreno-Cruz, Kate L. Ricke, Ken Caldeira

Juan B. Moreno-Cruz

Solar geoengineering is the deliberate reduction in the absorption of incoming solar radiation by the Earth's climate system with the aim of reducing impacts of anthropogenic climate change. Climate model simulations project a diversity of regional outcomes that vary with the amount of solar geoengineering deployed. It is unlikely that a single small actor could implement and sustain global-scale geoengineering that harms much of the world without intervention from harmed world powers. However, a sufficiently powerful international coalition might be able to deploy solar geoengineering. Here, we show that regional differences in climate outcomes create strategic incentives to form coalitions …

Upgraded Alo Rayleigh Lidar System And Its Improved Gravity Wave Measurements, Leda Sox, Vincent B. Wickwar, Joshua P. Herron, Marcus J. Bingham

Leda Sox

The Rayleigh-Scatter lidar system at the Atmospheric Lidar Observatory (ALO) on the Utah State campus is currently going through a series of upgrades to significantly improve its observational abilities. A specific objective of these upgrades is to expand the altitude range over which backscattered photons can be collected. A second objective is to increase the sensitivity of the instrument to be able to analyze the raw data at finer temporal and/or spatial resolutions. By measuring relative densities, the system will be able to produce absolute temperatures and relative density perturbations, which illustrate gravity wave structures. Gravity wave studies will significantly …

Results From An Extremely Sensitive Rayleigh-Scatter Lidar, Leda Sox, Vincent B. Wickwar

Leda Sox

Rayleigh-Scatter lidar systems effectively use remote sensing techniques to continuously measure atmospheric regions, such as the mesosphere (45-100km) where in situ measurements are rarely possible. The Rayleigh lidar located at the Atmospheric Lidar Observatory (ALO) on the Utah State campus is currently undergoing upgrades to make it the most sensitive of its kind. Here, the important components of these upgrades and how they will effect the study of a particular atmospheric phenomena, atmospheric gravity waves, will be discussed. We will also summarize what has been done to the system during this year to bring us to the threshold of initial …

Observations With The Most Sensitive Rayleigh-Scatter Lidar, Leda Sox, Vincent B. Wickwar, Joshua P. Herron, Marcus J. Bingham

Leda Sox

The mesosphere is the most unexplored region of the atmosphere. Its altitude range of 50-85 km lies in between the reaches of data collecting instruments like weather balloons and satellites. For this reason, remote sensing systems, such as lidar, which are able to employ ground-based instruments to make extensive measurements in this difficult to detect region. The Rayleigh-scatter lidar at USU is currently being redeveloped to be the most powerful and sensitive of its kind. This type of lidar exploits light and particle interactions, like those that account for the blue color of the sky, to make relative density and …

Small Scale Changes In Zooplankton Community In Relation To Stratification And Phytoplankton Thin Layers, Adam T. Greer Feb 2012

Small Scale Changes In Zooplankton Community In Relation To Stratification And Phytoplankton Thin Layers, Adam T. Greer

Adam T. Greer

Gelatinous zooplankton represent a poorly understood component of marine food webs in part because of difficulties estimating abundance using traditional net sampling techniques. The degree of vertical patchiness can influence the trophic impact of jellies, and the biophysical drivers of their distributions remain unknown. Using a towed In Situ Ichthyoplankton Imaging System (ISIIS), we examined the changes in jelly distributions during upwelling and relaxation events in Monterey Bay, CA. Sampling began at the end of a 12 d stretch of upwelling favorable winds. The first day of sampling was marked by a thin layer of high chlorophyll fluorescence and intense …

Impact Of Signal-To-Noise Ratio In A Hyperspectral Sensor On The Accuracy Of Biophysical Parameter Estimation In Case Ii Waters, Wesley J. Moses, Jeffrey H. Bowles, Robert L. Lucke, Michael R. Corson Jan 2012

Impact Of Signal-To-Noise Ratio In A Hyperspectral Sensor On The Accuracy Of Biophysical Parameter Estimation In Case Ii Waters, Wesley J. Moses, Jeffrey H. Bowles, Robert L. Lucke, Michael R. Corson

Wesley Moses

Errors in the estimated constituent concentrations in optically complex waters due solely to sensor noise in a spaceborne hyperspectral sensor can be as high as 80% or more. The goal of this work is to elucidate the effect of signal-to-noise ratio (SNR) on the accuracy of retrieved constituent concentrations. The large variation in the magnitude and spectral shape of the measured signal due to the wide range of constituent concentrations in coastal waters complicate the impact of SNR on the accuracy of estimation. Due to the low reflectance of water, especially in the near infrared region, the actual SNR encountered …

Satellite- And Ground-Based Co Total Column Observations Over 2010 Russian Fires: Accuracy Of Top-Down Estimates Based On Thermal Ir Satellite Data, Leonid Yurganov Jan 2011

Satellite- And Ground-Based Co Total Column Observations Over 2010 Russian Fires: Accuracy Of Top-Down Estimates Based On Thermal Ir Satellite Data, Leonid Yurganov

Leonid Yurganov

CO total column data are presented from three space sounders and two ground-based spectrometers in Moscow and its suburbs during the forest and peat fires that occurred in Central Russia in July–August 2010. Also presented are ground-based in situ CO measurements. The Moscow area was strongly impacted by the CO plume from these fires. Concurrent satellite- and ground-based observa- tions were used to quantify the errors of CO top-down emis- sion estimates. On certain days, CO total columns retrieved from the data of the space-based sounders were 2–3 times less than those obtained from the ground-based sun-tracking spectrometers. The depth …

Niche Of Harmful Alga Aureococcus Anophagefferens Revealed Through Ecogenomics, Christopher Gobler, Dianna Berry, Sonya Dyhrman, Steven Wilhelm Jan 2011

Niche Of Harmful Alga Aureococcus Anophagefferens Revealed Through Ecogenomics, Christopher Gobler, Dianna Berry, Sonya Dyhrman, Steven Wilhelm

Steven Wilhelm

Harmful algal blooms (HABs) cause significant economic and ecological damage worldwide. Despite considerable efforts, a comprehensive understanding of the factors that promote these blooms has been lacking, because the biochemical pathways that facilitate their dominance relative to other phytoplankton within specific environments have not been identified. Here, biogeochemical measurements showed that the harmful alga Aureococcus anophagefferens outcompeted co-occurring phytoplankton in estuaries with elevated levels of dissolved organic matter and turbidity and low levels of dissolved inorganic nitrogen. We subsequently sequenced the genome of A. anophagefferens and compared its gene complement with those of six competing phytoplankton species identified through metaproteomics. …

Determining Rates Of Virus Production In Aquatic Systems By The Virus Reduction Approach,, M.G. Weinbauer, J.M. Rowe, Steven Wilhelm Jan 2010

Determining Rates Of Virus Production In Aquatic Systems By The Virus Reduction Approach,, M.G. Weinbauer, J.M. Rowe, Steven Wilhelm

Steven Wilhelm

The reduction approach to assess virus production and the prokaryotic mortality by viral lysis stops new infection by reducing total virus abundance (and thus virus–host contacts). This allows for easy enumeration of viruses that originate from lysis of already infected cells due to the decreased abundance of free virus particles. This reoccurrence can be quantified and used to assess production and cell lysis rates. Several modifications of the method are presented and compared. The approaches have great potential for elucidating trends in virus production rates as well as for making generalized estimates of the quantitative effects of viruses on marine …

The Southeastern Coastal Plain: An Overview, Lee J. Florea, H L. Vacher Jul 2009

The Southeastern Coastal Plain: An Overview, Lee J. Florea, H L. Vacher

Lee J Florea, PhD, P.G.

Florida enjoys the highest density of large springs in North America (Scott et al., 2004); Silver Springs is just one of the 33 first-magnitude springs (mean flow greater than 100 cfs (2.8 m3/s), and there are hundreds of smaller springs (Fig. 6.2; see Meinzer, 1927, and Scott et al., 2004). They are supplied by spectacular underwater caves that are internationally recognized in the cave-diving community. Less well known are the many air-filled caves of the region (see Florea, 2006; Moore, 2006; Lane 1986). Though generally smaller than their aquatic counterparts, their beauty can rival the world’s best show caves. This …

The Cumberland Plateau Of Eastern Kentucky, Larry C. Simpson, Lee J. Florea Jul 2009

The Cumberland Plateau Of Eastern Kentucky, Larry C. Simpson, Lee J. Florea

Lee J Florea, PhD, P.G.

Eastern Kentucky contains almost the same Mississippian limestones that appear at Mammoth Cave in south-central Kentucky (Chapter 3). To the east these strata dip below the Appalachian Basin and reappear as the Greenbrier Group in the Virginias. The limestone outcrop in eastern Kentucky follows the western margin of the Cumberland Plateau and forms a ragged ribbon of karst that is continuous from southeastern Ohio through Kentucky and Tennessee and into northern Alabama. There are more than 2,000 documented caves comprising over 470 km of surveyed passage in the Kentucky segment of the Cumberland Plateau (Fig. 2.115). At least 14 are …

Caves And Karst Of West-Central Florida, Lee J. Florea, David Budd, Robert Brinkmann

Lee J Florea, PhD, P.G.

The real west-central Florida is far from the “Sunshine State” image of white sand beaches and palm trees. Gently rolling hills, dense jungle-like forests, pine and palmetto scrublands, impenetrable cypress swamps, and alligator-laden rivers are more common. Numerous crystal-clear springs offer a glimpse of the hidden world below – a world that could challenge the most imaginative Disney artists (Fig. 6.17).
