NPP Time Series

rainbow line

A time series of summary statistics derived from all the gridded NPP Land products at a number of fixed globally distributed locations is maintained and monitored by LDOPE personnel in order to enable synoptic quality assessment via the internet. Product time series analyses are important because they capture algorithm sensitivity to surface (e.g., vegetation phenology), atmospheric (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. Time series statistics are extracted at nine NPP Land golden tiles selected over areas that are expected to be representative of the variability of the majority of the NPP Land products. Golden tile browse images are also available for the most recent month of production. Follow steps to examine time series plots. Click here for more information.
