Access

Gotchas

  • MYD13Q1 is the Aqua-platform counterpart; combine for 8-day effective cadence
  • Cloud + snow masking is conservative; expect data gaps in winter at high latitudes
  • 16-day composites use BRDF-adjusted reflectances; raw daily NDVI is in MOD09GA
  • Other datasets: d004, d005
  • Questions: q01
