Harvard Time Series Center (TSC)
http://timemachine.iic.harvard.edu/search/

Harvard Time Series Center (TSC) is an interdisciplinary effort dedicated to creating the world's largest data center for time series and to developing algorithms to understand and analyze various aspects of these time series. The partnership of the data center and the analysis effort makes both discoveries of new and rare phenomena, and large scale studies of known phenomena possible. The TSC hosts closed to 1 billion time series, mainly from the field of astronomy but expanding to economics, health data, real estate data, etc. Each time series typically consists of 100-100,000 measurements, making the total number of measurements greater than a trillion! They have both time series that go back 100 years with measurements every few days and time series that were taken at 200Hz for short period of time. Their collection represents one of the largest and most interesting datasets in the world for time series and gives a unique opportunity for to analysts to test their algorithms at large scales. This is an unprecedented opportunity to be part of the development of computational algorithms and the making scientific discoveries across multiple fields and answer some of the most fundamental questions. For each time series in the database, the TSC maintains a list of links to relevant resources, including: a) Links to the original images via URLs; b) A list of metadata about the object (position on the sky, time of observation, wavelength of observation etc), and c) A list of provenance information regarding the process between the original images and time series. The TSC also maintains a full set of web services that can be accessed using any programming language such as Python, Perl etc. Using those web services one can query the database and retrieve a subset of the dataset. These capabilities have been used to create a web interface. This will be added to Data Mining Resources Subject Tracerâ„¢. This has been added to Research Resources Subject Tracerâ„¢ Information Blog.
