Description

The Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Vegetation Indices (MYD13A3) Version 6.1 data are provided monthly at 1 kilometer (km) spatial resolution as a gridded Level 3 product in the sinusoidal projection. In generating this monthly product, the algorithm ingests all the MYD13A2 products that overlap the month and employs a weighted temporal average.

`SummaryQA`						Quality reliability of VI pixel

SummaryQA Class Table

Value	Color	Description
0		Good Data: use with confidence
1		Marginal Data: useful, but look at other QA information
2		Snow/Ice: target covered with snow/ice
3		Cloudy: target not visible, covered with cloud
