Description

Schwaebische Alb half-monthly 1-km MODIS NDVI (V006; 2012 to 2015).

Format

raster::RasterBrick

Details

This dataset contains half-monthly 1-km MODIS NDVI observations for parts of the Schwaebische Alb, south-western Germany (Jan 2012 to Dec 2015). For both the 16-day Terra (MOD13A1.006) and Aqua-MODIS composite layers (MYD13A1.006), preprocessing included

• the conduction of a comprehensive quality control based on the 'pixel_reliability' and 'VI_quality' SDS and

• the subsequent creation of half-monthly composites based on the 'composite_day_of_the_year' SDS that line up exactly with the release interval of GIMMS NDVI3g.

This was followed by the combination of the sensor-specific layers into half-monthly maximum value composites and, finally, the application of a modified Whittaker smoother to account for non-captured clouds and fill newly introduced data gaps.
