 | | The Composite Data Set is similar to the daily data in structure and is derived from the Daily Data Set, however, the process of compositing removes much of the contamination due to cloud cover present in the Daily Data Set (Holben, 1986). |
 | | The Composite Data Set is particularly useful for studies of temporal and interannual behavior of surface vegetation and for developing surface background characteristics for use in climate modeling, however, if a completely cloud free background is required, further compositing may be necessary. |
 | | Certain anomalies may exist in the data set because of conditions inherent in the input data, for example, missing scan lines or orbits, incorrect or incomplete calibration coefficients, and many of these data are flagged with the Quality control indicator. |
