Year 1999 southeastern Louisiana marsh Normalized Difference Vegetation Index (NDVI) phenology record from Landsat 5 TM and Landsat 7 ETM+ of Path 22 and Rows 39 and 40

The data file consists of Normalized Difference Vegetation Index (NDVI) datasets of the southeastern Louisiana marshes generated from Landsat Surface Reflectance Climate Data Record (Landsat CDR) (Path 22 and Rows 39 and 40) in 1999. The projection is the Universal Transverse Mercator (UTM Zone 15 North). The datum is WGS-1984. Spatial resolution is 28.5 meters by 28.5 meters resampled to 30 meters by 30 meters. The dataset consists of 20 stacked files. They are NDVI datasets from sampling dates throughout 1999 (in turns of Julian Day of Year):10, 26, 42, 122, 138, 170, 210, 218, 26, 250, 258, 266, 274, 290, 298, 306, 314, 322, 330, 362.
