Description: We provide a set of functions to retrieve information about GIMMS NDVI3g files currently available online; download and re-arrange the bi-monthly datasets according to creation time; import downloaded files from native binary (ENVI) format directly into R based on the widely applied 'raster' package; extract accompanying quality flags and perform quality control; calculate monthly value composites (e.g. maximum value composites, MVC) from the bi-monthly input data; and derive long-term monotonous trends from the Mann-Kendall trend test, optionally featuring pre-whitening to account for lag-1 autocorrelation.
