The VIIRS Vegetation Health and Drought Products (VHDP) from NDE algorithm provides weekly estimates of the Vegetation Condition Index (VCI), Temperature Condition Index (TCI) and Vegetation Health Index (VHI). These indices are designed to characterize moisture (VCI), thermal (TCI) and total vegetation health (VHI) conditions in response to weather impacts. The VHP algorithm requires a smoothed Normalized Difference Vegetation Index (NDVI) and Brightness Temperature (BT) from VIIRS. A 15-week time series smoothing technique is used. Data in the middle of the time series present the best result, and so the data of the 7th week (prior) is the final product. The VIIRS NDVI and BT are adjusted to AVHRR in order to use a climatology from AVHRR. These VIIRS-based products provide mission continuity from the AVHRR on NOAA and MetOp series satellites. These products are distributed in the netCDF-4 file format with metadata attributes included.
