The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.

This collection contains web crawls performed as the pre-inauguration crawl for part of the End of Term Web Archive, a collaborative project that aims to preserve the U.S. federal government web presence at each change of administration. Content includes publicly-accessible government websites hosted on .gov, .mil, and relevant non-.gov domains, as well as government social media materials. The web archiving was performed in the Fall and Winter of 2016 to capture websites prior to the January 20, 2017 inauguration. For more information, see http://eotarchive.cdlib.org/.
Climate Data Analysis Tools
UV-CDAT is a powerful and complete front-end to a rich set of visual-data exploration and analysis capabilities well suited for climate-data analysis problems.

The UV-CDAT Project
UV-CDAT builds on the following key technologies:
The Climate Data Analysis Tools (CDAT) framework developed at LLNL for the analysis, visualization, and management of large-scale distributed climate data;
ParaView: an open-source, multi-platform, parallel-capable visualization tool with recently added capabilities to better support specific needs of the climate-science community;
VisTrails, an open-source scientific workflow and provenance management system that supports data exploration and visualization;
VisIt: an open-source, parallel-capable, visual-data exploration and analysis tool that is capable of running on a diverse set of platforms, ranging from laptops to the Department of Energy's largest supercomputers.
These combined tools, along with others such as the R open-source statistical
analysis and plotting software and custom packages (e.g. vtDV3D), form UV-CDAT
and provide a synergistic approach to climate modeling, allowing researchers to
advance scientific visualization of large-scale climate data sets. The UV-CDAT
framework couples powerful software infrastructures through two primary means:
Tightly coupled integration of the CDAT Core with the VTK/ParaView infrastructure to provide high-performance, parallel-streaming data analysis and visualization of massive climate-data sets (other tighly coupled tools include
VCS, VisTrails, DV3D, and ESMF/ESMP);
Loosely coupled integration to provide the flexibility of using tools quickly
in the infrastructure such as ViSUS, VisIt, R, and MatLab for data analysis and
visualization as well as to apply customized data analysis applications within
an integrated environment.
Within both paradigms, UV-CDAT will provide data-provenance capture and
mechanisms to support data analysis via the VisTrails infrastructure.
