The Triana satellite mission from L-1 for global vegetation monitoring

Triana is expected to deliver continuous full-disk multispectral images of the Earth by July 2001 through the Internet. The primary instrument on Triana is a calibrated multispectral imager, the Earth Polychromatic Imaging Camera (EPIC) with 10 spectral channels in the ultraviolet, visible and near infrared wavelength regions. Additional broadband radiometers will also measure the Earth´s reflected solar radiation from the entire globe continuously. These radiometers will be useful for monitoring global change on time scales from minutes up to the mission lifetime of 5 years. They will contribute unique new data to help solve the outstanding solar radiation/climate problem of our time: how much solar energy is absorbed in the atmosphere?
