We demonstrate a synchronously pumped fiber optical parametric oscillator tunable from 795 nm to 860 nm. The FOPO operates in the normal dispersion regime and generates highly chirped pulses at the output allowing for significant pulse energy scaling

To address the need for a high quality data set based upon field observations suitable for parameterization, calibration, and validation of terrestrial biosphere models, we have developed a comprehensive global database on net primary productivity (N

Consistent data on terrestrial net primary productivity (NPP) are urgently needed to constrain model estimates of carbon fluxes and hence to refine our understanding of ecosystem responses to climate change. The NPP data have been collected in a coor

The three objectives of this paper were: to summarize net primary production (NPP) and carbon allocation patterns for boreal forests, to examine relationships between climatic and biological variables and NPP, and to examine carbon allocation coeffic

The Earth Observing System (EOS) instrument teams must validate the operational products they produce from the Terra spacecraft data. As a pilot for future validation activities, four EOS teams (MODIS, MISR, ASTER, and Landsat-7) and community expert

Reducing uncertainty in predictions of regional-scale models depends on meaningful contrasts with field measurements. This paper introduces a two-stage process that works from the premise that an appropriate goal for regional models is to produce rea

The synthesis and modeling of ecological processes at multiple spatial and temporal scales involves bringing together and sharing data from numerous sources. This article describes a data and information system model that facilitates assembling, mana

Progress in modeling the global carbon cycle is inhibited by the lack of a high-quality data set based upon field observations of net primary productivity (NPP) with which to calibrate, parameterize, and evaluate terrestrial biosphere models. Under t

An electron cyclotron resonance (ECR) reactor was used to develop a low damage CF{sub 4}/O{sub 2}/Ar etch process for patterning submicron features in SiN{sub x} films on GaAs substrates. Statistically designed experiments were performed to optimize

A microdialysis method is described which allows for the quantitative determination of extracellular analyte concentration under transient conditions. The method provides the extracellular concentration and the in vivo probe recovery as a function of
