Aerosol Observing System (AOS) Handbook
The Aerosol Observing System (AOS) is a suite of in situ surface measurements of aerosol optical and cloud-forming properties. The instruments measure aerosol properties that influence the earth’s radiative balance. The primary optical measurements are those of the aerosol scattering and absorption coefficients as a function of particle size and radiation wavelength and cloud condensation nuclei (CCN) measurements as a function of percent supersaturation. Additional measurements include those of the particle number concentration and scattering hygroscopic growth. Aerosol optical measurements are useful for calculating parameters used in radiative forcing calculations such as the aerosol single-scattering albedo, asymmetry parameter, mass scattering efficiency, and hygroscopic growth. CCN measurements are important in cloud microphysical models to predict droplet formation.

Cimel Sunphotometer (CSPHOT) Handbook
The Cimel sunphotometer (CSPHOT) is a multi-channel, automatic sun-and-sky scanning radiometer that measures the direct solar irradiance and sky radiance at the Earth’s surface. Measurements are taken at pre-determined discrete wavelengths in the visible and near-IR parts of the spectrum to determine atmospheric transmission and scattering properties. This instrument is weather-proof and requires little maintenance during periods of adverse weather conditions. It takes measurements only during daylight hours (sun above horizon).

Development & Optimization of Materials and Processes for a Cost Effective Photoelectrochemical Hydrogen Production System
The overall project objective was to apply high throughput experimentation and combinatorial methods together with novel syntheses to discover and optimize efficient, practical, and economically sustainable materials for photoelectrochemical production of bulk hydrogen from water. Automated electrochemical synthesis and photoelectrochemical screening systems were designed and constructed and used to study a variety of new photoelectrocatalytic materials. We evaluated photocatalytic performance in the dark and under illumination with or without applied bias in a high-throughput manner and did detailed evaluation on many materials. Significant attention was given to -Fe2O3 based semiconductor materials and thin films with different dopants were synthesized by co-electrodeposition techniques. Approximately 30 dopants including Al, Zn, Cu, Ni, Co, Cr, Mo, Ti, Pt, etc. were investigated. Hematite thin films doped with Al, Ti, Pt, Cr, and Mo exhibited significant improvements in efficiency for photoelectrochemical water splitting compared with undoped hematite. In several cases we collaborated with theorists who used density functional theory to help explain performance trends and suggest new materials. The best materials were investigated in detail by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visual spectroscopy (UV-Vis), X-ray photoelectron spectroscopy (XPS). The photoelectrocatalytic performance of the thin films was evaluated and their incident photon

LED Surgical Task Lighting Scoping Study: A Hospital Energy Alliance Project
Tungsten-halogen (halogen) lamps have traditionally been used to light surgical tasks in hospitals, even though they are in many respects ill-suited to the application due to the large percentage of radiant energy outside the visible spectrum and issues with color rendering/quality. Light-emitting diode (LED) technology offers potential for adjustable color and improved color rendition/quality, while simultaneously reducing side-effects from non-visible radiant energy. It also has the potential for significant energy savings, although this is a fairly narrow application in the larger commercial building energy use sector. Based on analysis of available products and Hospital Energy Alliance member interest, it is recommended that a product specification and field measurement procedure be developed for implementation in demonstration projects.

Temperature, Humidity, Wind and Pressure Sensors (THWAPS) Handbook
The temperature, humidity, wind, and pressure system (THWAPS) provide surface reference values of these measurements for balloon-borne sounding system (SONDE) launches. The THWAPS is located adjacent to the SONDE launch site at the Southern Great Plains (SGP) Central Facility. The THWAPS system is a combination of calibration-quality instruments intended to provide accurate measurements of meteorological conditions near the surface. Although the primary use of the system is to provide accurate surface reference values of temperature, pressure, relative humidity (RH), and wind velocity for comparison with radiosonde readings, the system includes a data logger to record time series of the measured variables.

Tri-Cities Index of Innovation and Technology
In 2001 and 2004, the Economic Development Office of Pacific Northwest National Laboratory published companion reports to the Washington Technology Center Index studies that provided additional information on the Tri-Cities (Kennewick-Richland-Pasco) area of the state, its technology businesses, and important advantages that the Tri-Cities have as places to live and do business. These reports also compared the Tri-Cities area to other technology-based metropolitan areas in the Pacific Northwest and nation along critical dimensions known to be important to technology firms. This report updates the material in these earlier reports, and highlights a growing Tri-Cities metropolitan area.

Department of State's Report to Congress and U.S. Oversight of Civilian Assistance to Pakistan Can Be Further Enhanced
Correspondence issued by the Government Accountability Office with an abstract that begins "Pakistan is a key U.S. ally in the effort to combat terrorism and violent extremism. Taliban, al Qaeda, and other terrorists have used parts of Pakistan to plan and launch attacks on Afghan, U.S., and NATO security forces in Afghanistan, as well as on Pakistani citizens and security forces in Pakistan. Enhancing the effectiveness of civilian assistance to Pakistan is one of the U.S. government's top foreign policy and national security priorities. Foreign assistance is vital to help the government of Pakistan overcome the political, economic, and security challenges that threaten Pakistan's long-term stability. Since 2002, the United States has provided over $18 billion in foreign assistance and reimbursements to Pakistan, about two-thirds of which has been security-related. In October 2009, Congress passed the Enhanced Partnership with Pakistan Act of 2009, which authorizes up to $1.5 billion a year for development, economic, and democratic assistance (henceforth referred to as "civilian assistance") to Pakistan for fiscal years 2010 through 2014. In the act, Congress declares that the United States requires a balanced, integrated, countrywide strategy to support Pakistan's efforts that does not disproportionately focus on security-related assistance. The act …
