The dataset consists of composited seasonal surface reflectance images (4 seasons per year) created from the full time series of Landsat TM/ETM+/OLI imagery. The imagery has been composited over a season to produce imagery which is representative of that period, using techniques which will reduce contamination by cloud and other problems. This creates a regular time series of reﬂectance values which captures the variability at seasonal time scales. The beneﬁts are a regular time series with minimal missing data or contamination from various sources of noise as well as data reduction. Each season has exactly one value (per band) for each pixel (or is null, i.e., missing), and the value for that season is assumed to be the representative of the whole season. The algorithm is based on the medoid (in reﬂectance space) over the time period (the medoid is a multi-dimensional analogue of the median), which is robust against extreme values.
This dataset was produced by the Joint Remote Sensing Research Program using data sourced from US Geological Survey.
This product captures surface reflectance at seasonal (ie three-monthly) time scales, forming a consistent time series from 1987 - present. For applications that focus on vegetation changes, the fractional cover and ground cover products may be more suitable.
Summary of processing: Landsat imagery less than 80% cloud cover downloaded > corrections and masking > medoid calculated for seasonal surface reflectance.
