Annual seasonality trends of Normalized Difference Vegetation Index (NDVI), Maricopa County, Arizona, 2001-2018

Description: A dataset with 18 years (2001-2018) of consistent,
spatial and temporal patterns of Normalized Difference Vegetation
Index (NDVI) values in Maricopa County AZ Abstract: This dataset consists of 18 years (2001-2018) of consistent,
spatial, and temporal patterns of vegetation indices, as expressed by
the Normalized Difference Vegetation Index (NDVI), in Maricopa County,
AZ. I download and process images, at 250m resolution, from the
Moderate Resolution Imaging Spectroradiometer (MODIS). MODIS uses the
atmospherically-corrected reflectance in the red, near-infrared, and
blue wavebands to calculate vegetation indices. In the last decades,
vegetation indices have been widely used for monitoring the seasonal
variation of vegetation, document vegetation structure, productivity,
overall health, and land cover changes and measure vegetation
productivity in desert landscapes. NDVI is also of high interest to
investigate the potential distribution of plant and animal species and
to investigate the effect of climate change on vegetation
productivity. MODIS data were obtained from https://lpdaac.usgs.gov,
maintained by the NASA EOSDIS Land Processes Distributed Active
Archive Center (LP DAAC) at the USGS Earth Resources Observation and
Science (EROS) Center, Sioux Falls, South Dakota. Spatial Extent: Maricopa County, AZ, USA.
