Pixel-wise MODIS NDVI trends in Iraq and Iran, 2000–2025: Google Earth Engine scripts and results

Google Earth Engine and Python scripts, result tables and map layers supporting the manuscript "Widespread greening in Iraq and Iran, 2000–2025: pixel-wise MODIS NDVI trends that hold across sensors and largely lack a rainfall trend". The workflow uses MODIS MOD13Q1 V061 (SummaryQA = 0, annual medians, ≥ 8 composites per year, ≥ 15 valid years), Sen's slope and Mann–Kendall tests on the native MODIS grid, with robustness checks against the start year, the Aqua sensor (MYD13Q1), CHIRPS rainfall trends and MCD12Q1 land cover.
