This document introduces the algorithm, data sets, and usage methods of the MODIS Land Cover Dynamics (MCD12Q2) product.
This user guide explains the Collection 6.1 (C6.1) MODIS Land Cover Dynamics Product (MCD12Q2), which maps global land surface phenology metrics at 500m resolution. It details algorithmic changes from the C5 product, data access, and QA/QC metrics. The guide also explains how phenometrics are derived from NBAR-EVI2 time series and how vegetation cycles are identified and validated using spline fitting and amplitude thresholds.
The product includes 25 SDSs recording phenophase dates, vegetation cycle counts, and QA scores. It supports multiple vegetation cycles per year and handles calendar year boundaries. Data is delivered in UNIX-epoch time and includes metrics like greenup onset, peak greenness, senescence, and dormancy dates.
| Spatial Resolution | 500 meter |
|---|---|
| Temporal Resolution | Annual |
| Data Product | MCD12Q2 |
| Phenometrics | Greenup, peak greenness, senescence, dormancy |
| Data Format | UNIX-epoch time |
The product maps global land surface phenometrics at a 500 meter spatial resolution.
The processing pipeline allows product generation 6 months after the end of the calendar year.
A valid greenup period requires an NBAR-EVI2 amplitude greater than or equal to 0.1.
