We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.Read about the Web Unification Project
Description
The MCD12Q2 Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the MCD12Q2 Version 6.1 data product.
The Terra and Aqua combined Moderate Resolution Imaging Spectroradiometer (MODIS) Land Cover Dynamics (MCD12Q2) Version 6 data product provides global land surface phenology metrics at yearly intervals from 2001 to 2019. The MCD12Q2 Version 6 data product is derived from time series of the 2-band Enhanced Vegetation Index (EVI2) calculated from MODIS Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectance (NBAR). Vegetation phenology metrics at 500 meter spatial resolution are identified for up to two detected growing cycles per year. For pixels with more than two valid vegetation cycles, the data represent the two cycles with the largest NBAR-EVI2 amplitudes.
Provided in each MCD12Q2 Version 6 Hierarchical Data Format 4 (HDF4) file are layers for the total number of vegetation cycles detected for the product year, the onset of greenness, greenup midpoint, maturity, peak greenness, senescence, greendown midpoint, dormancy, EVI2 minimum, EVI2 amplitude, integrated EVI2 over a vegetation cycle, as well as overall and phenology metric-specific quality information. A low-resolution browse image showing greenup is also available when viewing each MCD12Q2 granule. SDS layers may be multi-dimensional with up to two valid vegetation cycles.
For areas where the NBAR-EVI2 values are missing due to cloud cover or other reasons, the data gaps are filled with good quality NBAR-EVI2 values from the year directly preceding or following the product year.
Known Issues
Known issues are described on pages 5 and 6 of the User Guide.
The following changes and improvements were implemented for inputs to MODIS Version 6 land cover dynamics data products: (1) Additional Science Dataset (SDS) layers were included in Version 6, (2) Changes were implemented to better capture phenometrics in systems with multiple vegetation cycles per year, (3) Version 6 methodological approach increased the reliability of retrieved phenometrics in tropical, arid, and semi-arid ecosystems, (4) Modifications were designed to more accurately represent phenometrics in systems where NBAR-EVI2 time series do not closely resemble logistic growth patterns, (5) Version 6 delivers phenometrics in a more usable and intuitive way when vegetation cycles cross calendar boundaries, particularly in the Southern Hemisphere, (6) Vegetation cycles in a product year are determined by the date of peak NBAR-EVI2 within the product's calendar year, (7) Date representation changed to days since January 1, 1970, and (8) Overall quality improvements with phenometric-specific quality layers provided.

The table below lists the variables contained within a single granule for this
dataset. Variables often contain observed or derived geophysical measurements
collected from a variety of sources, including remote sensing instruments on
satellite and airborne platforms, field campaigns, in situ measurements, and
model outputs. The terms variable, parameter, scientific data set, layer, and band
have been used across NASA’s Earth science disciplines; however, variable is the
designated nomenclature in NASA’s Common Metadata Repository (CMR).
Variable metadata attributes such as Name, Description, Units, Data Type, Fill
Value, Valid Range, and Scale Factor allow users to efficiently process and analyze
the data. The full range of attributes may not be applicable to all variables.
Additional information on variable attributes is typically available in the data,
user guide, and/or other product documentation.
For questions on a specific variable, please use the Earthdata Forum.
