  Land Long Term Data Record:    Time Series

A time series of summary statistics derived from all the LTDR products at a number of fixed globally distributed locations is maintained and monitored by the LTDR QA personnel in order to enable synoptic quality assessment via the internet. Time series statistics are extracted at all aeronet sites and also nine MODIS Land Golden Tiles. Product time series are important because they capture algorithm sensitivity to surface (e.g. vegetation phenology), atmosphere (e.g. aerosol loading) and remote sensing (e.g. sun-surface-sensor geometry) conditions that change temporally, and because they allow changes in the instrument characteristics and calibration to be examined. Please select the year and an aeronet site (listed in aphabetical order) or tile and biome combination).
