We estimate the strength of the bandpass-integrated thermal emission from the extrasolar planet HD 209458b at 3.6, 4.5, 5.8, and 8.0 μm using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. We observe a single secondary eclipse simultaneously in all four bandpasses and find relative eclipse depths of 0.00094 ± 0.00009, 0.00213 ± 0.00015, 0.00301 ± 0.00043, and 0.00240 ± 0.00026...

Thls paper explores the potential for airborne remote sensing for atmospheric sciences research. Passive and active techalques from the microwave to visible bands are discussed. It is concluded that technology has progressed sufficiently in several areas that the time Is right to develop and operate new remote sensing instruments for use by the community of atmospheric scientlste as general pur...

We present a possibility of tailoring the near-surface composition profiles of pressure sensitive adhesive (PSA) films by an exposure to atmospheres of different relative humidities (RHs). The statistical copolymer P(EHA-stat-20MMA) with a majority of ethylhexylacrylate (EHA) and a minority of methylmethacrylate (MMA), being cast from a toluene based solution, is chosen as a model system. The n...

The horizontal spectra of atmospheric wind and temperature at the tropopause have a steep -3 slope at synoptic scales, but transition to -5/3 at wavelengths of the order of 500-1,000 km [Nastrom, G. D. & Gage, K. S. (1985) J. Atmos. Sci. 42, 950-960]. Here we demonstrate that a model that assumes zero potential vorticity and constant stratification N over a finite-depth H in the troposphere exh...

[1] Methyl chloride (CH3Cl) is a naturally occurring, ozone-depleting trace gas and one of the most abundant chlorinated compounds in the atmosphere. CH3Cl was measured in air from the Taylor Dome ice core in East Antarctica to reconstruct an atmospheric record for the Holocene (11–0 kyr B.P.) and part of the last glacial period (50–30 kyr B.P.). CH3Cl variability throughout the Holocene is str...

The relationship between wind and pressure in the equatorial zone of a barotropic, nondivergent atmosphere is The results indicate that it is extremely difficult The impact of this conclusion upon examined. Cyclostrophic effects prove to be of major importance. to devise pictorial models of the wind-pressure relationship near the equator. operational low-latitude analysis by both subjective and...

This paper presents an analytical review of data on the interaction of volatile corrosion inhibitors with the atmosphere, vaporization processes, methods of experimental and computational estimation of the vapor pressure of organic compounds, and effects of vaporization conditions and compound structure on vapor pressure.

Moisture is one essential condition for seed germination, and poor germination is very costly to growers. There is, nevertheless, little experimental evidence concerning the effects of different percentages of available moisture (5) on germination; more study of the subject is essential. Since most vegetable seeds are planted at shallow depths, there may be rapid fluctuations of soil moisture a...

This study examines the sensitivity in predicted levels of atmospheric organic particulate matter (M(o), microg m(-3)) as those levels may potentially be affected by changes in relative humidity and temperature. In a given system, for each partitioning compound, f(g) and f(p) represent the gaseous and particulate fractions (f(g) + f(p) = 1). Sensitivity in the M(o) levels becomes dampened as th...
