We present the CR-precis structure, that is a general-purpose, deterministic and sub-linear data structure for summarizing update data streams. The CR-precis structure yields the first deterministic sub-linear space/time algorithms for update streams for answering a variety of fundamental stream queries, such as, (a) point queries, (b) range queries, (c) finding approximate frequent items, (d) ...

The sparsity of data in the southwest Pacific Ocean has limited our understanding of the effect of oceanography in regional ocean climate, and on the role that the ocean plays in ocean-atmosphere interaction. Consequently, comprehensive climate studies of the southwest Pacific region have been constrained due in part to this relatively poor spatial (on regional to large scales) and temporal (on...

Global climate models do not have sufficient spatial resolution to represent the atmospheric and land surface processes that determine the unique regional heterogeneity of the climate of the State of Washington. If future large-scale weather patterns interact differently with the local terrain and coastlines than current weather patterns, local changes in temperature and precipitation could be ...

325 Land hydrologic responses to meteorological forcing involve complicated exchanges of moisture and energy between soil, vegetation, snowpack, groundwater, and the overlying atmospheric boundary layer. These exchanges occur in the form of many interactive natural hydrologic processes, including precipitation, snow and soil water melting and freezing, infi ltration, storage and movement of soi...

During the late Miocene, a dramatic global expansion of C4 plant distribution occurred with broad spatial and temporal variations. Although the event is well documented, whether subsequent expansions were caused by a decreased atmospheric CO2 concentration or climate change is a contentious issue. In this study, we used an improved inverse vegetation modeling approach that accounts for the phys...
