INDOEX aerosol optical depths and radiative forcing derived from AVHRR

Creator:: Tahnk, William Richard
Abstract:: The Indian Ocean Experiment (INDOEX) had as a primary objective determining the radiative forcing due to anthropogenic aerosols over climatologically significant space and time scales: the Indian Ocean during the winter monsoon, January-March. During the winter monsoon, polluted, low-level air from the Asian subcontinent blows over the Arabian Sea and...

Aerosol optical depth and direct radiative forcing for INDOEX derived from AVHRR: Observations, January–March 1996–2000

Creator:: Tahnk, William R. and Coakley, James A., Jr.
Abstract:: Visible and near infrared reflectances from NOAA-14 Advanced Very High Resolution Radiometer (AVHRR) daytime passes are used to derive optical depths at 0.55 μm, an index of aerosol type, continental or marine, and the direct effect of the aerosol on the top of the atmosphere and surface solar radiative fluxes...

Improved Calibration Coefficients for NOAA-12 and NOAA-15 AVHRR Visible and Near-IR Channels

Creator:: Tahnk, William R. and Coakley, James A. Jr.
Abstract:: A time history of the calibration coefficients for channels 1 and 2 of the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-12 and NOAA-15 spacecraft is presented. The history is based on reflectances observed for the interior zones of the Antarctic and Greenland ice sheets previously obtained with the...

Effect of Protease Inhibitors on Steady-State Pharmacokinetics of Oral Norethindrone Contraception in HIV-Infected Women

Creator:: Atrio, Jessica, Stanczyk, Frank Z., Neely, Michael, Cherala, Ganesh, Kovacs, Andrea, and Mishell, Daniel R., Jr.
Abstract:: OBJECTIVE: Pharmacokinetic interactions exist between combined oral contraceptives and protease inhibitors (PI). However, such information is lacking for progestin-only oral contraception. We sought to define the steady-state pharmacokinetic interaction between norethindrone (NET) and PI in HIV-infected women. METHODS AND DESIGN: We conducted an open-label, prospective, nonrandomized trial to characterize the...

PRex: an experiment to investigate detection of near-field particulate deposition from a simulated underground nuclear weapons test vent

Creator:: Keillor, Martin E., Arrigo, Leah M., Baciak, James E., Chipman, Veraun, Detwiler, Rebecca S., Emer, Dudley F., Kernan, Warnick J., Kirkham, Randy R., MacDougall, Matthew R., Milbrath, Brian D., Rishel, Jeremy P., Seifert, Allen, Seifert, Carolyn E., and Smart, John E.
Abstract:: A radioactive particulate release experiment to produce a near-field ground deposition representative of small-scale venting from an underground nuclear test was conducted to gather data in support of treaty capability development activities. For this experiment, aCO₂‐driven “air cannon” was used to inject ¹⁴⁰La, a radioisotope of lanthanum with 1.7‐d half-life...

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...

Morning-to-Afternoon Evolution of Marine Stratus Polluted by Underlying Ships: Implications for the Relative Lifetimes of Polluted and Unpolluted Clouds

Creator:: Christensen, Matthew W., Coakley, James A., Jr., and Tahnk, William R.
Abstract:: Ship tracks appearing in both the morning and afternoon Moderate Resolution Imaging Spectroradiometer (MODIS) imagery for the Pacific Ocean off the west coast of the United States were used to study the morning-to-afternoon evolution of marine stratus polluted by underlying ships and nearby uncontaminated stratus. Analyzed 925-hPa winds were used...

Effect of changes in relative humidity on aerosol scattering near clouds

Creator:: Twohy, Cynthia, Coakley, James A. Jr., and Tahnk, William R.
Abstract:: Many investigations using satellite data have determined that aerosol optical depth and cloud cover are correlated and some have interpreted the correlation as evidence of an aerosol indirect effect on clouds. This study uses in situ aircraft observations taken during the Indian Ocean Experiment (INDOEX), February–March 1999, and mostly over...
