Ambiguity in wind direction has long been an impediment to applications of wind observations from the Seasat scatterometer (SASS). Three months of unambiguous global SASS vector winds (7 July-10 October 1978) have recently become available from the Goddard Space Flight Center(GSFC) Laboratory for Atmospheric Sciences. The directional ambiguities were removed...
Vector winds measured by the Seasat-A Satellite Scatterometer (SASS) are analyzed to determine the spatial structure of oceanic surface winds over wavelengths from 200 to 2200 km. The analysis is performed in four latitudinal bands in the Pacific Ocean. Sampling characteristics of SASS preclude the possibility of determining full two-dimensional...
Nucleic acid extracted from dormant cane phloem of
grapevines affected by grapevine stem-pitting disease (SP)
formed a high molecular weight (MW) band on 1.0% and 0.8%
agarose gels. The band was unique to diseased vines. Other
bands appeared from samples of both diseased and virus-free
vines, but did not associate...
Denitrification, the biological or chemical reduction of ionic nitrogen oxide or dinitrogen, has not been widely studied in forest ecosystems despite widespread interest in other facets of the forest nitrogen economy. This study had three main objectives: to determine whether potential for denitrification exists in forest riparian and hill slope...
When a shade ring is used to shield a pyranometer from direct solar radiation, a correction to the
measured diffuse radiation is necessary to account for diffuse radiation intercepted by the ring. A general
analysis is developed to relate shade-ring corrections to the radiance distribution of diffuse radiation. The
corrections...
The angular distribution of diffuse radiation was measured from May 1976 to May 1977 with a set of
purpose-built actinometers. Radiance distributions for 98 overcast hours were fitted well by an expression
similar to the conventional function for a 'standard overcast sky' (SOC). However, values of the coefficient
b averaged...
