Data: MODIS (MAIAC) EVI and NDVI indices

Scale factor: 10000

Coverage: South America land

Time period: 2000 to 2018 (starting in 2000, Julian day 64) - Note: 2018 might have a bias due to processing - I advise to use 2000-2017

Spatial resolution: 1 km

Temporal resolution: 16 days

Coordinate reference system: geographic projection, datum WGS-84

Processing details:

  • The original MODIS (MAIAC) data were described by Lyasputin et al. 2011 (https://doi.org/10.1029/2010JD014986). The daily MODIS (MAIAC) surface reflectance data from collection 6, acquired from Terra and Aqua satellites, are available from the MCD19A1 product (https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/6/MCD19A1). The Bidirectional Reflectance Distribution Function (BRDF) model parameters are available from MCD19A3 product (https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/6/MCD19A3)
  • The daily MCD19A1 data at 1 km spatial resolution were normalized using the BRDF parameters and Ross-Thick Li-Sparse (RTLS) model considering a fixed nadir view and a 45 deg. solar zenith angle using the parameters from the MCD19A3 product
  • The daily data were aggregated into 16-day composites by the pixel’s median. The 16-day composites always start from Day Of Year (DOY) 016 and end with DOY 352. Therefore, the remaining days from 352 to 365/366 were not used. This procedure was used to facilitate inter-annual comparisons
  • The tiles that cover the South America were mosaicked and re-projected from sinusoidal to geographic projection
  • The Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) were calculated using standard formulas. The EVI parameters were: C1 = 6, C2 = 7.5, L = 1, G = 2.5

File(s) format:

  • Zip files for EVI and NDVI - one per year:
    • Inside them there are raster files with ".tif" format, one per 16-day window. The filename syntax is "maiac_southamerica_DATA_YYYYDOY.tif", where YYYY is the year (from 2000 to 2018), and the DOY is the Julian day of the last day of the composite window, i.e. YYYYDOY for January 2005 for DOY from 001 to 016 is 2005016, from DOY 017 to 032 is 2005032, etc.
  • Csv files with the YYYYDOY and "real" dates for the time period
