Records of 1 April snow water equivalent (SWE) are examined here using multiple linear regression against reference time series of temperature and precipitation. This method permits 1) an examination of the separate roles of temperature and precipitation in determining the trends in SWE; 2) an estimation of the sensitivity of...
A previous comparison of data from the Halogen Occultation Experiment (HALOE) and of output from the NCAR Community Climate Model (CCM2) in austral spring overstated the effect of dehydration in the southern polar vortex on lower strato spheric water vapor in part due to shortcomings in the HALOE retrieval algorithm...
The application of general circulation models (GCMs) to stratospheric chemistry and transport both permits and requires a thorough investigation of stratospheric water vapor. The National Center for Atmospheric Research has redesigned its GCM, the Community Climate Model (CCM2), to enable studies of the chemistry and transport of tracers including water...
This paper shows a small sampling of the atmospheric fields provided by the
Moderate Resolution Imaging Spectroradiometer (MODIS), which is installed on both the
Terra and Aqua satellites of the Earth Observing System. These fields include macroscale
fields like cloud fraction, cloud top pressure, cloud optical depth, and column water...
Preservative treatment of whole, wood-based composite products (mainly panels) has disadvantages; problems largely stem from swelling, strength loss, and incomplete or inappropriate penetration during treatment, and distortion during redrying. Pretreatment of comminuted wood prior to mat lay-up is one alternative, though the addition of chemicals may affect bonding during subsequent...
This study examines productivity change in the Mid-Atlantic surfclam and ocean quahog fishery, which has been managed since 1990 using Individual Transferable Ouotas (ITQ). Productivity change is estimated through a Malmquist index from 1981-2008, capturing change before and after implementation of the quota system. We then decompose the index to...
A mesoscale model is used to examine the dynamics of northwest flow over the Santa Barbara Channel region.
Three cases are considered, each characterized by typical summertime synoptic conditions, but with differences
in pressure gradient strength and marine boundary layer depth (MBL). The first case examines a relatively deep
MBL...
Oxygen and strontium isotopic composition of sedimentary pore fluids obtained by drilling at the Chile Triple Junction have been used to obtain information on the diagenesis and transport mechanisms of fluids. Samples were collected from three sites located on an east-west transect of the pre-collision zone (Sites 859, 860, and...
