As the primary scientific computing facility for the DOE's Office of Science, National Energy Research Scientific Computing Center – a division of the Lawrence Berkeley National Laboratory –Electric heated Ironing Machine for sale
is one of the largest facilities in the world dedicated to basic science research. A sizable portion of the supercomputing resources at NERSC is allocated to global climate change research. That's nearly 150 million processor-hours of highly-tuned computational might focused on an issue that is critical to humanity's future.
With each generation of supercomputers exponentially more powerful, climate models grow increasingly detailed. Science Writer Jon Bashor notes that the best global models of the late 1990s treated the western United States from the Pacific Ocean to the Rocky Mountains as a uniform landmass, even though there are topological features, like mountains, deserts and bodies of water, that affect climate. With the advances in hardware and software over the last two decades Steam heated ironing machine for sale
, today's models have improved resolution down to 10-kilometer square blocks, while the next generation will drill down to the 2-kilometer level.
The more fine-grained the models become, the more accurate the predictions will be.Climate change is one of the most pressing issues facing our planet today, so accuracy is extremely important. People want to know if the models can be trusted and to what degree. Confidence is especially critical in estimates of anthropogenic climate change. Models are often vetted by checking certain scenarios against real-world results. A common evaluation technique is to "predict" climate sequences that have already occurred.
