Work pants worn by loggers in Western Oregon, 1920-1970

Creator:: Gullickson, Mark A.
Abstract:: With the arrival of European settlers to Western Oregon nearly 150 years ago came new methods of forest management. Early settlers' forest practices consisted of little more than harvesting what seemed an endless supply of timber. Forestry in the 20th century eventually incorporated such management concerns as re-forestation, biodiversity, wildlife...

A direct-conversion offset-cancellation mixer in 2.4 GHz CMOS

Creator:: Lehne, Mark A.
Abstract:: We present a new circuit design for adaptive offset cancellation in a fully differential 2.4 GHz CMOS direct conversion mixer. Our circuit structure is a modification of a Gilbert cell mixer in which offsets are cancelled by injecting cancellation currents into the legs of the mixer by dynamically varying the...

Soil surface CO2 efflux across the climatic gradient of the Oregon Transect for Terrestrial Ecological Research (OTTER)

Creator:: Martin, Mark A.
Abstract:: Soil CO2 efflux is a major contributor of CO2 to the atmosphere. The rate that CO2 is respired out of the soil is called the soil flux (Fs). Many variables alter Fs. These variables differ drastically in the variety of ecosystems found on the earth. It is important to understand...

Determining relative benefits to communities from urban and agricultural land use change in Napa County, California

Creator:: Bernard, Mark A.
Abstract:: Urban sprawl and the establishment of greenbelts to separate growing cities and towns has become a popular topic of conversation among land use professionals. Economists focus on urban growth in terms of land rents and have sought market solutions such as transfers and purchases of development rights to slow this...

Multiyear Advanced Very High Resolution Radiometer observations of summertime stratocumulus collocated with aerosols in the northeastern Atlantic

Creator:: Matheson, Mark A., Coakley, James A., and Tahnk, William R.
Abstract:: Advanced Very High Resolution Radiometer (AVHRR) 4-km data were collected over the northeast Atlantic for May–August 1995–1999. Aerosol optical depth at 0.55 μm was retrieved in pixels identified as being cloud-free ocean. In pixels identified as containing clouds from single-layered, low-level cloud systems over oceans, the following cloud properties were...

Effects of threshold retrievals on estimates of the aerosol indirect radiative forcing

Creator:: Matheson, Mark A., Coakley, James A., and Tahnk, William R.
Abstract:: Empirical estimates of the aerosol indirect radiative forcing often rely on threshold cloud retrievals applied to multispectral satellite imagery data. In such retrievals, pixels having radiances that surpass prescribed thresholds are assumed to be overcast even if they are only partially cloud covered. This assumption leads to cloud visible optical...

Aerosol and cloud property relationships for summertime stratiform clouds in the northeastern Atlantic from Advanced Very High Resolution Radiometer observations

Creator:: Matheson, Mark A., Coakley, James A., and Tahnk, William R.
Abstract:: Advanced Very High Resolution Radiometer (AVHRR) 4-km data collected over the northeastern Atlantic off the coast of the Iberian Peninsula for May to August 1995 were used to investigate the feasibility of empirically deriving estimates of the aerosol indirect radiative forcing. A retrieval scheme was used to derive cloud visible...

Why pest plant control and native plant establishment failed : a restoration autopsy

Creator:: Wilson, Mark V., Ingersoll, Cheryl A., Clark, Deborah Louise, 1950-, and Wilson, Mark G.
Abstract:: Explaining restoration failure can be as important as touting success. We used a series of studies to understand the failure of techniques commonly used to restore wetland prairies in the Willamette Valley of western Oregon. Burning, fallowing, and solarization (covering tilled plots with plastic sheeting to heat the soil) had...

Retrieval of cloud droplet size from visible and microwave radiometric measurements during INDOEX: Implication to aerosols’ indirect radiative effect

Creator:: Liu, Guosheng, Shao, Hongfei, Coakley, James A., Curry, Judith A., Haggerty, Julie A., and Tschudi, Mark A.
Abstract:: The effective radius of water cloud droplets is retrieved using remotely sensed passive microwave and visible data collected by aircraft during the Indian Ocean Experiment. The purpose of this study is to assess the aerosols’ effect on cloud microphysical and radiative properties. To study this effect, we investigate the relationships...
