One year of daily averaged scanner outgoing longwave radiation (OLR) 2.5 degree region measurements from the Clouds and the Earth's Radiant Energy System (CERES) instrument is made available on the Internet/Web for use by the scientific and educational community. This year of daily averaged data is from scanner measurements taken by the CERES instrument on the Terra satellite which is in a sun-synchronous orbit with an equator crossing of about 10:40. The data set spans the period from March 2000 through February 2001 and can be viewed and accessed using a web browser located on a server at NASA, Langley Research Center. The brower uses a live access server (LAS) developed by the Thermal Modeling and Analysis Project at NOAA's Pacific Marine Environmental Laboratory. LAS allows researchers to interact directly with the data to view, select, and subset the data in terms of month, year, latitude, and longitude. In addition to OLR measurements, statistics that result from calculating regional averages will be discussed, in particular standard deviations and number of measurements that go into the averages.
