NEON terrestrial field observations: designing continental-scale, standardized sampling

Integrative Taxonomy for Continental-Scale Terrestrial Insect Observations

Although 21(st) century ecology uses unprecedented technology at the largest spatio-temporal scales in history, the data remain reliant on sound taxonomic practices that derive from 18(th) century science. The importance of accurate species identifications has been assessed repeatedly and in instances where inappropriate assignments have been made there have been costly consequences. The Nation...

Oceanic and Terrestrial Sources of Continental Precipitation

[1] The most important sources of atmospheric moisture at the global scale are herein identified, both oceanic and terrestrial, and a characterization is made of how continental regions are influenced by water from different moisture source regions. The methods used to establish source-sink relationships of atmospheric water vapor are reviewed, and the advantages and caveats associated with eac...

Continental-scale comparisons of terrestrial carbon sinks estimated from satellite data and ecosystem modeling 1982–1998

A simulation model based on satellite observations of monthly vegetation cover was used to estimate monthly carbon fluxes in terrestrial ecosystems from 1982 to 1998. The NASA–CASA model was driven by vegetation properties derived from the Advanced Very High Resolution Radiometer (AVHRR) and radiative transfer algorithms that were developed for Moderate Resolution Imaging Spectroradiometer (MOD...

Designing algorithms by sampling

The paper describes a method for empirical algorithm design, called database learning, using which an algorithm is constructed based on the solutions produced by an oracle on samples from the input space. We present experimental results of applying the strategy to designing heuristics for the problem of constructing a maximum independent set of a given graph. The heuristic designed by database ...
