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?.
