Terra Instrument Data
After a successful launch in December 1999, the instruments on Terra began science operations on February 24, 2000, following completion of final orbital maneuvers to phase with the orbit of Landsat 7. The release dates of specific data products depend on the complexity of the product and successful calibration and validation. The data quality from all of Terra's sensors is exceptional. Current and subsequent processing of the data will yield enhanced scientific utility.
Teams of scientists
worldwide were selected to receive the data to perform research
in areas of international concern. Additionally, EOS data and products
are available to all users, without restriction, at no more than the
cost of dissemination, regardless of the intended use.
